Is Your Roof Weatherproof?

Is Your Roof Weatherproof?

Getting ready for the rainy season.

The roof is the first line of defence of any residential or commercial building against the weather elements. The blazing sun, heavy rainfall, and strong winds don’t easily impact a well-maintained roof. This is why it is essential to check the roof’s condition with every change in season and the rainy months are coming. Is your roof ready for heavy rain?

The Importance of Regular Roof Maintenance

Keeping the roof well-maintained is the best way to protect the home or building from harsh climate conditions. Neglecting the roof results in water leaks and structural damages and could cost thousands of dollars to fix and a roof in a state of disrepair is also a risk to the health and safety of the occupants.

Giving the roof at least twice a year inspection, by yourself or professionally, will help keep it in tiptop shape. Taking care of the basic roof repair and maintenance yourself is relatively easy, but there are cases when roof repair is better left to professionals. The roof experts will know exactly where to look and what to do with different roof issues.

Getting the Roof Ready for Heavy Rain

Give the roof a careful look and inspect for damages and signs of a leak and do not ignore even just one seemingly small issue. A minor gap can easily give way to bigger roof trouble. Here are some tips on what homeowners can do to secure their roof for the upcoming rainy season:

  • Clean the roof’s dirt and debris hotspots.
  • Check for damaged, loose, or missing roof tiles.
  • Look for water and rust damage.
  • Inspect the flashing for any damage.
  • Take a look around the chimney and vents.
  • Clear away tree branches.
  • Consider replacing the old, broken-down roof.

Clean the Roof’s Dirt and Debris Hotspots

The gutters, downpipes, and drains are debris hotspots and prone to blockages. When these areas get blocked, rainwater will overflow and get under the eaves and into the roof cavity. Another thing about uncleared dirt and debris is that mould and algae can form and cause the gutter and roof to rot.

Cleaning the roof of dirt, leaves, twigs, and other debris will help clear away surface water. Don’t forget to clean the roof valleys as well to prevent leaves from making their way into the gutters and cause blockage during a heavy downpour.

Rainwater can easily flow and move away from the roof with a clean gutter, downpipes, and drains. Homeowners should therefore make roof cleaning a priority during roof maintenance.

Check for Damaged, Loose, Or Missing Roof Tiles

Inspect the roof space for any cracks, loose, displaced, or missing roof tiles and get them fixed right away. Don’t forget to also check inside the roof space for signs of roof or sarking damage. A light passing through whatever tiny cavity there indicates the presence of cracks or tiles shifting out of place.

Look for Water and Rust Damage

The roof is also prone to water and rust damage, and the most obvious sign of these would be discolouration. Another tell-tale sign would be the presence of mould, lichen or algae. Moisture build-up causes these signs and should not be ignored.

Roofing material made from concrete or terracotta will show discolouration as a sign of water damage. Metal and tin roof, meanwhile, will have rust on it. Any of these signs means only one thing: The roof is leaking or is about to.

Inspect the Flashing for Damage

Roof flashing may look small, thin, and insignificant, but these roof installations do a crucial job of directing the water flow away from delicate roof areas as this is typically installed in places where water might seep in, such as valleys and joints, protrusions, ridges and around vents and chimneys.

Since roof flashing is critical in keeping the water out, it must not be ignored during roof inspections. Repair or replace loose and rusted flashing, and the roof will do a better job of keeping the water out.

Take A Look Around the Chimney and Vents

Heavy rain, coupled with whipping wind, is a recipe for disaster for any roof, driving water up into projections like chimneys, vents and pipes, and even skylights. Unfortunately, these installations are also huge leak hotspots and should not be ignored. Look for cracks, gaps, worn-out sealant or flashing, and signs of water damage around these areas. Problems can be easily repaired with sealant, caulk and flashing and shingle installation.

Clear Away Tree Branches

Leaves, twigs, and dead branches may fall off and accumulate on the roof. These will become a massive contributor to clogged gutters, downpipes and drains. Tree branches may also scratch the roof and wear away the tiles as they move in the wind.

To prevent damages on the roofing and for better defence against leak, clear away any hanging branches by cutting hanging limbs and foliage to make sure nothing will touch or fall on the roof.

Consider Replacing Old or Broken Roofing

In the case of an old roof with recurring damages, it might be best to consider a replacement. If it’s been more than 25 years since its last replacement, it may become saggy, with badly damaged shingles or mould and will have seen better days. It might be time for a new one.

Although this is an expensive option, perhaps the last resort, a fresh roof installation gives the home more robust weather protection. Think of new shingles, neat flashing, and better sealants. Sometimes, replacing the whole roof can be more cost-effective in the long run than having constant spot repairs.

Keep Your Roof Ready for All Seasons with Sydney Roof and Building Supplies

It is a good idea to check the roof after major weather events like hailstorms but giving it a careful assessment before the bad weather approaches would be extremely beneficial. Make it a point to check the roof’s status from time to time.

If your roof shows signs of damage and deterioration, it will not stand a chance against heavy rains. Give your roof a fighting chance and have it ready for all seasons.

A 2021 Guide to Buying Roof Paint

A 2021 Guide to Buying Roof Paint

Is it time to upgrade your roof paint?

Giving the house a facelift can be a great way to spend spare time and where better place to start that with a roof makeover? Painting the roof is one way of making a home stand out. Helping to keep the roof in top shape, reducing the need to spend money replacing part or all of a neglected roof. Here’s a quick guide to buying roof paint in 2021 for homeowners and property investors alike.

 

Different Roof Materials Need Different Paints

Before starting on painting the roof, find out what it is made from, to determine the type of paint that is needed.

Painting Concrete roof tiles

Technically speaking, concrete roof tiles don’t normally require painting. However, most homeowners have them painted for aesthetic improvement. Many roof painters, on the other hand, recommend painting them to help extend their lifespan.

Roof Protect Concrete Tiled Primer is one of the best products to use on concrete tiles. It is made using 100 per cent acrylic emulsion, which intensifies its adhesive property. This creates a solid barrier that disables the absorption of calcium salts. This primer protects the roof membrane that allows it to hold its colour and gloss longer than most other concrete primers. It can cover approximately six metres per litre and can be bought in 15-litre drums.

Painting Colorbond and metal roofs

Metal roofs are the cheaper alternative to tiled roofs, and they are 100 per cent recyclable. Colorbond roofing is even cheaper than other metals and has become popular in Australia. It weighs just 1/10th of other metal roofing and does not absorb any water. It is also safer against bush fires, as it is non-combustible.

Colorbond roof sheets don’t necessarily need painting, but painting Colorbond and metal roofs could make them more durable. When buying roof paint, consider Roof Protect Metal Primer Plus. It is manufactured using premium styrene acrylic, which makes membrane layers highly adhesive for years to come. This paint can be matched to more than 30,000 colours.

Rust Inhibitor Primer deals with rust. It is made using an acrylic emulsion with quite a high adhesion and was also engineered to include several pigments that have rust killing properties. It dries to the touch in 30 minutes or less and dries completely hard in 4 to 5 days.

 

What is The Best Colour for a Roof?

Now that the roof material has been identified, the next step is to choose the colour. This is the fun part, especially now that there are more options to choose from than ever before. However, choosing the right colour roof paint is not only a question of aesthetics.

Light colours can make a home more energy efficient

Roof colour can help energy efficiency - lighter colour roofs reflect the sun’s heat much better than darker ones. Roof painted in white, beige, light bronze, light green, peach or light blue is recommended in sunny regions.

Roofs with a lighter colour will protect homes can also help reduce the load on air-con, which can lower energy bills by at least 25%.

Roof Colour Must Compliment the Building’s Colours

When buying roof paint, consider the home’s overall style, including the siding or wall, windows, doors, and the surrounding landscape.

Take a look at different colour samples at different times of the day. This will help make sure that the colour you like looks good both when the sun is shining brightly and when it is going down, as colours look more subdued during sunset.

Achieve your desired effects

Today’s colour choices are virtually limitless. So, achieving a particular effect with the roof colour is relatively easy. A colour that contrasts with your home’s sidewalls will make your home command attention. On the other hand, choosing a similar colour will create a monochromatic effect that conveys a more classic feel.

Light versus dark colours also has a pleasant effect. A roof with a lighter colour will make the house seem taller. In contrast, a darker colour will make a tall roof appear less daunting.

Take note of neighbourhood trends

It is understandable if to have the home’s overall look reflect the owner’s personal taste, however, it wouldn’t hurt to consider the general trends of roof colours in the neighbourhood. Some neighbourhoods have an unwritten aesthetics trend and it would be a good idea to work with it, instead of making the house stand out for the wrong reasons.

Roofing Specialists Must-Have Equipment and Tools

Roofing Specialists Must-Have Equipment and Tools

Roofing tools and gears for a safe and successful Sydney roofing project.

Most of the time, Australian homeowners maintain their roofs by hiring roofing experts. That is if they have an allocated budget for the said maintenance. If not, they tend to rely on DIY and watching roof-related videos without knowing that there should be proper equipment and tools for this type of household job.

Here's the catch: depending on the gravity of the roof damage, be it a simple roof check-up, shingle removal, or a complete roof restoration, anyone with experience on DIY projects can do this task as long as they have the right equipment and tools. It is also an opportunity for people interested in the roofing business to get started: by knowing what equipment and tools they should have.

What Equipment and Tools Should I Have?

In every roofing-related project, the risk of damage and injury is always present. Checking your roof without being prepared can be hazardous and may result in major injuries.

Bringing the inappropriate materials is ill advised, as it can lead to more roof damage than helping you get your job done. To keep you well-prepared and informed, Sydney Roof and Building Supplies has listed down the essential equipment that you should have to work on your roof:

For Safety and Protection

Before climbing up your roof, have yourself equipped with the tools that prioritise your safety. Better be ready than to be sorry to avoid the inconvenience of going up and down your roofing. Ready your task with this safety equipment:

  • Safety goggles

It is one of the most important items that you should wear to protect you from unwanted shingles or any objects that fly around while working on your roof.

  • Dust masks

Aside from unwanted objects up in the air, it is also expected that dust will be present when you are working on your roof. Don't forget to wear a dust mask so you can breathe comfortably while doing your tasks.

  • Harness

As much as you might think you can prevent accidents such as slipping by just being careful, admit it, they happen. You need to prepare yourself in case it happens to you. Be ready by using a harness that is Australian-safety approved!

  • Roof Shoes

You cannot just go to your roof in your typical daily footwear. It is smart to wear roof-approved footwear such as steel-toed boots to prevent injuries.

  • Ladders or Aerial Work Platform (AWPs)

For roof experts, getting an AWP eases the hassle of going up with a ladder. However, suppose you are just starting a roofing business or DIY-ing. In that case, it is essential to choose a perfect ladder, preferably a fibreglass and lightweight, that can keep you safe if you are using electricity.

Must-Have Tools

Now that you are adequately equipped for your safety before you begin any of your roof-projects, you must prepare yourself to bring the appropriate tools. The tools you'll be using should be suitable for working on your roof. You can refer to the following to know the basics:

  • Tool Belt

Help yourself avoid the inconvenience of going up and down to get a tool you've missed with a tool belt. Getting yourself a tool belt can save you much time and give you the convenience to carry and store tools such as roof nails easily.

  • Retractable Utility Knife

Getting a utility knife can help you with your roof repairs and installations. By having a retractable one, you can avoid any accidents as you can release and hide the blade  with one hand. Make sure to use the one that stores an extra blade so you won't need to worry about keeping them in your tool belt.

  • Measuring Tape

One of the essential tools that you should never forget is a measuring tape. A measuring tape helps you double-check the measurements in your roof project. It avoids the worry of you buying the wrong size of any roof materials.

  • Nail Gun

A nail gun is usually powered by air compressors that help you apply nail to your roof surfaces quickly. Nail guns can help you save time and finish your work faster.

  • Trimming Trays

Trimming trays will serve as your lifesaver to avoid bits of roof tiles, or shingles getting stuck in your gutters. They also help you to clear up your space after your project.

Remember: The Appropriate Tools Prevent Damage

Whether you are starting your own roofing business or planning to work on your residential roofing, getting the correct tools helps you prevent damage. The equipment and tools we recommend are only some of the must-haves that you should invest in to save up on costs for future use. Later on, upgrading your tools will be easier as you learn new knowledge and practices while doing your roof projects.

Be attentive also of the materials these tools are made of and be wary of accidental mishandling. Investing in these materials will help you improve your skills with roof concerns moving forward.

How Powered Ventilation Systems Work

How Powered Ventilation Systems Work

What are powered vents and what are the signs that indicate you need one?

Have you ever felt an unexplained discomfort or uneasiness inside your house? Sometimes, even if you have regularly maintained your ceilings, you might still feel that the air inside your house does not seem to move around as it should. This is not healthy, especially if you have infants and elderly, or members of the family with respiratory challenges.

For this reason, many roof experts recommend installing ventilation systems in your house. One type of ventilation systems to consider is the powered ventilation system. Read on to find out more about powered ventilation systems and the role they play in many residences and even commercial establishments.

Powered Ventilation Systems vs Natural Vents

Powered ventilation systems are a type of roof ventilator. Just like standard roof ventilators, these help you get rid of humid and stale air to bring in fresh and new air from the outside during summer. It enables you to balance the cold weather during the winter season to help you manage the winter’s chilly air.

Unlike natural ventilators, powered vents require electric power to run and make the most out of their function. For natural vents, the best example would be your very own windows. Using windows for ventilation, however, is not always practical, especially if there are weather constraints (e.g., cold weather, strong winds). As such, a powered ventilation system is a practical addition and it can be readily available to use for any season.

How Powered Ventilation Systems Work

A powered ventilation system works by using fans, usually attached to the roofs, to pull the hot and dirty air out with greater force. Powered vents are best used in enclosed spaces or in selected areas that may cause extreme moisture and humid air, like toilets or kitchens. Powered vents filter the air that goes in to your home to. They balance the humid and stale air over the clean and cool air or vice versa.

Enclosed spaces without proper ventilation can lead to roof damage or moisture build-up that may lead to mould growths. This can cause much stress to a homeowner, especially since mould may cause harm, and repairing their damage doesn’t come cheap!

Getting Started with Powered Ventilators

As mentioned, aside from relying on natural ventilation, you should also consider installing powered ventilators in your household to avoid unexpected damage to your roof or any part of your home. As choosing the perfect ventilation system for your space can be challenging, you can start by familiarising yourself with the three types of powered ventilators:

  1. Supply: this type of ventilation system brings air in, but it does not remove it. Getting this type of ventilator is not too ideal, especially in bush fire areas, as supply vents may bring in hot and smoky air inside.
  2. Exhaust: these are commonly used in kitchens and bathrooms to that help you remove the humid air from your home. It can be tricky as some exhaust vents do not entirely drive out the air outside but send it into your ceiling or attic that may cause condensation leading to moisture.
  3. Balanced: is a mix of supply and exhaust ventilation. Balanced vents are mostly installed throughout the whole house to balance bringing in the fresh air and removing the condensed air. The typical installation of balanced ventilation goes like this:
  • Vents supply new and fresh air in the bedrooms, living rooms, or entertaining rooms were most people usually gathers and;
  • Vents exhaust the humid and moist air from areas where it is commonly generated in enclosed spaces such as toilets, kitchens, attic, and basements.

Note that these powered ventilators do not filter and remove the moisture from inside a house. However, they help filter the air to remove dust and pollen from the outside.

Should You Install Powered Ventilation Systems In Your House or Building?

You might not be aware that you need a powered vent installed. Here are some signs that indicate it’s time to consider a powered ventilation system installed by your reliable roofing contractor:

  • You’re experiencing uncomfortable hot weather during summertime.
  • There are rust stains on your plumbing system.
  • Strong or foul odours do not disappear as fast as before.
  • There is visible discolouring of floors, wall paints, and tiles.
  • Mould growth appears on the walls and ceiling.

Should you find some of these signs visible in your home, we recommend seeking an expert to further check what type of ventilation would go well inside your house.

Find the Right Ventilation System at Sydney Roof & Building Supplies

Finding the perfect ventilation is challenging but your trusted roofing contractor will be able to help you decide whether you need a wind driven vent or a powered ventilation system. Once your roofing specialist confirms that you need a vent, head to Sydney Roof & Building Supplies to find the right deal.

From eave vents to solar vents, our catalogue of available ventilation systems is always available. We outsource our products globally to give our customers top-quality products at fairly reasonable prices.

If electricity bills worry you, we got you covered! We have solar-powered roof ventilators such as the SupaVent wind-driven ventilation, which does not require electricity and will work fine for households that plan to install solar panels in the future.

Call us at 02 8090 3483 from 6 AM to 4 PM or visit us at Unit 2, 6 Yatala Rd, Mt Kuring-Gai 2080 from Monday to Friday. You may also send us your enquiry at mark@srbs.com.au or marie@srbs.com.au and we will get back to you as soon as possible.

What Are The Best Roof Insulation Options?

What Are The Best Roof Insulation Options?

Why Use Insulation in A Property?

Apart from being a building legislation requirement, insulating your property by adding insulation to your ceiling, walls, and under-flooring has plenty of benefits for your house or office but, in case you aren’t up to speed with the most important reasons to insulate a property, he team at Sydney Roof & Building Supplies are here to give you a run-down:

1.      Increased thermal efficiency

This is the most obvious benefit of installing insulation - you can maintain your desired temperature indoors. Property insulation must be of good quality and well-fitted, so you can enjoy the kind of climate that you want inside your home regardless of the season.

2.      Lower electricity and gas bills

When you insulate your home, there will be less need to run your air conditioners and heaters. This could mean lower gas and electricity bills – and more savings in your pocket.

3.      Soundproofing

One of the incredible advantages of insulation is its capability of soundproofing your home. That extra layer of insulation material keeps outside noise out and indoor chatter in.

4.      Efficient building process

If you install insulation while building your home, the project would be easier and faster to complete. Construction work can proceed uninterrupted because the insulation covers the interior of the building.

5.      Reduce your carbon footprint

Since you’ll be turning on your heating and cooling appliances less frequently, you will be better able to help the environment, because you will be more energy efficient with insulation, keeping your house warm or cool without spending as much energy. This means less power is required by your property, which in turn means less Carbon is created and therefore you are helping the planet heal.

Where Should You Install Insulation?

The objective of installing insulation is to seal your entire house from draughts. Therefore, it is best to fit the material in key areas where air seeps into your home – mainly through the ceiling, walls, and under the floors. Insulating your ceiling, walls and floors can dramatically reduce the need for expensive cooling and heating systems. You should install insulation in the following places:

  • Ceilings: Hot air rises, so heat tends to escape through your ceiling during winter, but good insulation can stop this from happening. Similarly in the summer, reflective insulation can prevent the sun’s rays from penetrating your house through the ceiling.
  • Walls: Modern homes now have wall insulation to create a more balanced indoor climate all year round. Insulation can be placed in between wooden wall batons, or in brick wall cavities.
  • Underfloors: Air can also escape through gaps your floor boards, floor coverings or just through thin material, so it’s crucial to have proper insulation that improves the thermal efficiency of your house.

 

Types of Roof Installation for Australian Homes

There are three types of insulation in Australian homes today:

  • Reflective insulation
  • Bulk insulation
  • Spray foam

Traditional bulk and reflective insulation are still the most common, but cellulose spray foam is fast catching up. Here is some more detailed information about each type: 

Bulk insulation: Trap heat in tiny bubbles

Readily available in hardware stores, bulk insulation is the most popular form of building insulation. It works by trapping air inside millions of tiny bubbles to prevent heat from entering the building, because air is generally less thermally conductive than solid materials. You can choose from a wide range of materials, available in rolls, boards and batts.

A disadvantage of bulk insulation, however, is that it cannot be compressed, because the air pockets will be compromised.

Reflective insulation: Bounce heat away

If you are looking for cost-efficient home insulation, then reflective insulation is your best option. Reflective insulation is made of a top foil layer backed by a sheet of plastic or paper, with the shiny surface deflecting heat away from your home.

For reflective insulation to work properly, the reflective foil must be installed facing down and should be kept clean at all times. Builders can combine bulk and reflective insulation to create hybrid configurations that ensure maximum insulating performance. 

Cellulose spray foam: The future of insulation

Relatively new to the world of insulation, spray foam can be very effective and offers insulation like no other material can. Its R-value is higher than traditional forms of insulation and it is highly resistant to moisture so it is less likely to sag over time.

Cellulose insulation is a form of bulk insulation that is seamless, durable, and environment-friendly. This insulation is applied by spraying or blowing into the ceiling, walls, or under the floor and the foam expands to form a thick layer of insulation. Cellulose insulation is perfect for hard-to-reach places that are difficult to seal with traditional insulation materials.

Cellulose insulation is fantastic for stopping heat transfer as it fills all gaps around the sprayed area, helping your home maintain its indoor ambient temperature all year round – so you save more money on heating and cooling.

Spray foam insulation is mostly made of pulverised recycled paper treated with boric acid and borax to make it fire and pest resistant and can also be combined with batts and foil to form a hybrid.

What Are The Types of Roof Insulation Material? 

Fibre Glass

Roof insulation is made from several different materials, with glass wool as the most common in homes and commercial buildings. Some glass wool roof insulation options include:

  • Knauf earth wool ceiling batts
  • Pink glass wool ceiling batts
  • Gold Bradford Hi-Performance ceiling batts
  • Black Bradford hypoallergenic ceiling batts

Polyester

Polyester insulation is made from recycled PET plastics, bonded together by heat for a rigid, flexible and hypoallergenic structure. Polyester roof insulation options include:

  • Greenstuf polyester ceiling insulation
  • Bradford Polymax thermal ceiling batts

Foil

Foil insulation creates a reflective barrier against the sun’s rays. The R-value of reflective insulation will ultimately depend on how it is installed and what climate you have in your location. Foil roof insulation options include:

  • Kingspan Air-Cell Insulbreak 70
  • Sisalation Metal Roof Sarking

Hybrid

Hybrid options combining bulk and reflective roof insulation include:

  • Knauf earth wool blanket roll with foil facing
  • Fletcher Permastop blanket insulation

Should You Install Batts or Rolls in Your Roof?

Batts and rolls are both effective at sealing crevices in your home, but the main difference is how they are cut and installed. Insulation rolls can be rolled out in large ceiling spaces that have few obstacles. Meanwhile, batts are easier to install in small ceiling spaces since they are pre-cut to fit any space.

How to Choose the Best Insulation

Choosing the best insulation for your home will depend on factors such as roof type, thermal resistance required, climate and budget. Some insulation types are not suitable for damp places while some materials are designed to work as a moisture barrier. Make sure that the insulation you choose is suitable for your ceiling, walls or underfloor.

Here at Sydney Roof & Building Supplies, we stock many different types of insulation panels to suit your property design and construction. Our roof insulation materials combine an insulating core with a radiant barrier that protects your interiors from excessive heat transfer.

What are Roof Cowls?

What are Roof Cowls?

Find out the benefits of roof cowls.

Firstly, have you ever gone up into the attic and smelled that old, musty smell? That can be a sign of mould and mildew, and severe infestations can be a health hazard.

Similarly, have you ever had soot blown into your home from your chimney? Or had rain washing soot down into your fireplace? Soot can be hard to clean and gets into every nook and cranny.

Roof Cowls exist to prevent these problems. They are fittings that sit on top of a chimney in order to improve efficiency, soiling and air flow.

5 Types of Roof Cowls

Roof cowls come in all shapes and sizes, and all of them have their own uses. If you’re looking for a cowl to install, it will help to know the basic types first. Some of the most common roof cowl types are:

  • Standard Cowls
  • Vertical and Jet Cowls
  • Copula styled Cowls
  • Wind Directional Cowls
  • Spinner Cowls (also known as Whirlybirds or Turbines)

1.      Standard roof cowls

Standard roof cowls have a sheet covering placed on top of the exhaust output area. These are an excellent choice for homes or buildings with no unique ventilation requirements. If, for example, your exhaust only comes from your attic or fireplace, then this may be for you.

2.      Vertical and jet cowls

Even though they look like they’re for industrial use, these cowls are suited to residential purposes as well as industries. Vertical and jet cowls transport air further away from the rooftop to prevent contamination. These are especially useful for exhausts that contain large amounts of soot or other materials. Another excellent design feature is that even though these cowls spew air upwards, they’re still well-protected from precipitation.

3.      Cupola-style cowls

Cupola-styled cowls are often used for their aesthetic value, especially in residential buildings. These can either be used for topping off chimneys or for decorative purposes. Cupola-styled cowl designs are flexible, and there is a variant that’s sure to fit any type of home.

4.      Wind directional cowls

Strong winds can be a problem for chimneys since they can cause a downdraft, blowing soot back in. Roof cowls can somewhat help with this problem, but there’s none more effective than wind directional cowls. These are equipped with hinges that allow them to swing based on wind direction. This effectively blocks off wind from entering your chimney, therefore preventing downdrafts from happening.

5.      Spinner cowls/whirlybirds/turbines

Spinner cowls, also known as whirlybirds or turbine vents, are usually spherical in shape. These are made up of metal blades inside an encasement, with the blades spinning to allow ventilation. The spinning motion of the blades pulls air out from underneath and ejects it outward through the encasement, allowing proper circulation of air inside the building.

The Benefits of Roof Cowls

You may already have an idea of the many functions that roof cowls have based on the types we mentioned but installing roof cowls can benefit your home or building in many other ways that you may not have considered, including:

  • Roof Cowls help your roof last longer.

Roofs are prone to wear and tear, perhaps more so than other parts of your home. As such, you need to take proper care of your roofs to minimise damage. Using roof cowls is an excellent way of doing this as they can somewhat help protect from precipitation. Some types of roof cowls, like jet and vertical cowls, also protect your roof from contaminated air, which allows your roof to require less frequent, thorough cleaning.

  • Roof Cowls help regulate building temperature.

Roof cowls, like ridge vents, are also excellent at keeping the temperature inside buildings at favourable levels. Temperatures fluctuate depending on the season, and some types of roof cowls help prevent temperatures from reaching extremes. This can help the rest of your home regulate temperatures more efficiently.

  • Roof Cowls help you save on electricity costs.

Air conditioning and temperature control can potentially consume a lot of electricity, driving up your electric bill. Since your roof cowl helps in regulating temperature, this eases the burden on electricity consumption. You’ll get to save on energy bills which make the cowls a good investment in the long run.

  • Roof Cowls improve air quality in buildings.

One of the primary functions of roof cowls is to allow better ventilation. Some types of cowls, such as whirlybirds and jet cowls actively pull air from inside the building. This allows air to circulate better, ejecting stale air and allowing fresh air to circulate.

  • Roof Cowls protect chimneys from precipitation.

Some cowls are specially shaped to redirect precipitation away from your chimneys. This means that water and snow can’t get in, keeping the chimney and the inside of your home protected. You wouldn’t want rain getting in your fireplace, after all – this means that roof cowls help to keep your home clean.

  • Roof Cowls prevent downdrafts.

A Guide to Roof Flashing Repair and Installation

A Guide to Roof Flashing Repair and Installation

Whether you're hiring a roof specialist or doing it yourself, here's what you need to know about roof flashing installation.

When it comes to maintaining your roof, one of the most important elements to remember is the flashing. Flashing plays a huge part in keeping your house safe and secure from water leaks, mould contamination, building rot, and even structural collapse. You may think that such a minor part of your roof is insignificant, but ignoring your flashing’s scheduled repair or maintenance can have dire consequences.

If you don’t remember the last time you had your roof flashing looked at, it may be time to look into scheduling a check-up with your trusted roofing contractor. Of course, it would be better if you also have the know-how on how flashing works and how it’s maintained. To help you get started, we’ve prepared a guide to roof flashing repair and installation in NSW.

What is roof flashing?

What is roof flashing?

Roof flashing is a thin material that roofers use to direct the flow of water away from critical areas of your house or building roof. Usually made from galvanised steel, it is often placed wherever the plane of a roof meets a vertical surface like a dormer or a wall. You install flashing to surround special areas on your roof like skylights, chimneys, and vents.

Common Types of Roof Flashing

Common Types of Roof Flashing

There are heaps of roof flashing types available, and the one you should choose depends on the function you require it for. To give you an idea of what type of flashing you should have for your house or building, here are some of the most common types of flashing available in Australia:

  • Valley Flashing

This type of flashing is made from a sheet of metal, and it is usually pre-painted to match the colour of the roof’s shingles. The valley flashing is often used and fastened on open valleys.

  • Skylight Flashing

You need to make sure that water can’t get in around your skylights. Installing flashings around the skylight area will solve that problem. Sometimes, skylights will already have complementary flashing, but there are times when repairs or maintenance are necessary. When that happens, it’s better to reach out to your roofing contractor so that you can select the right type of flashing based on your need.

  • Kickout Flashing

This type of flashing directs water into the gutter, away from the wall. It sits between the gutter and the step flashing.

  • Drip Edges

Drip edges are flashings made from thin metal placed at the edge of the roof. This type of flashing is used to have the water drip off the roof while preventing damage in a home or causing a leak.

Nowadays, there are pre-made flashing pieces you can purchase. However, most roofing professionals cut their own roof flashing from sheet metal in order to tailor-fit the flashing to their clients’ home.

If you are planning to install flashing yourself, you should be careful with your selection. Make sure that you get a pre-made flashing that’s built specifically for roofs. That way, you will be able to avoid breakage due to incompatibility.

Repairing Your Roof’s Flashing

Repairing Your Roof’s Flashing

There are several ways to repair roof flashing, depending on the issue you are addressing and the materials you are repairing. If you’re planning to repair your roof’s flashing yourself, here are some things you should know:

  • Small corroded spots or small holes in the flashing

If you see any corroded spots or small holes in your roof’s flashing, you should repair them as soon as possible. Thankfully, for holes up to 2cms across, this issue is easy to solve. All you have to do is plug pinholes with roofing cement and fix the holes with a patch that’s made from the similar material as your flashing.

  • Extreme flashing corrosion

If your roof’s flashing is badly-corroded, a simple repair may not be enough. You might need to completely replace your corroded flashing with a new one. To do that, remove a few shingle rows and old flashings and add the new one. You should bring back the shingles you moved once you’re done.

  • Loose drip edging

If you think your current drip edging has become loose, you should reseal it right away. Resealing is quite easy. Just make sure that you seal the flashing beneath the single and refrain from sealing the drip edge along the eaves.

When repairing roof flashing, make sure to use high-quality materials and ensure you do a good and thorough repair job. Otherwise, the hard work and money you’ve put into repairing your flashing will be wasted.

Tips in Maintaining Your Flashing

Tips in Maintaining Your Flashing

Know more about flashing maintenance by reviewing the top tips indicated below:

  • Locate leaks

When doing flashing maintenance, one of the first things you should do is locate any possible leaks. You would usually have an idea of this already if you encounter water leak issues with your chimney, skylights, or other parts of your home.

  • Lock down your flashing as tight as you can

Over time, your flashing may become loose. That usually happens when the screws anchoring it become loose or when the metal around the edges of the hole wears away. To solve this issue, simply buy the same screws as your flashing and screw them back tightly. Cover the screws with roofing cement immediately after.

  • Re-caulk the flashing of your chimney

Your flashing is usually attached to your chimney’s mortar. Over time, that mortar can be damaged or destroyed. In order for it to remain effective, it will need to be replaced carefully.

Types of Roof Flashing

Types of Roof Flashing

Roof flashing is critical in making sure water does not enter your roof.

Sydney homes receive a battering from the extreme weather conditions it experiences all year round. Heat waves, hail storms, heavy rainfalls, and  string wind, can all take a toll on your home, particularly the roof. Over time, these weather events may affect the structural integrity of your home’s roof system, resulting in damaged roofs and leaks.

This is why routine maintenance is important in reinforcing your roof and making its individual parts effective against any weather. One of the most overlooked yet, extremely crucial part of the roof is the unassuming, simple roof flashing.

What is Roof Flashing?

Roof flashing is a small elements of a roofing system. But, it does a significant waterproofing job. Flashing is designed primarily to prevent water from getting into the house through the gaps on the roof. It is estimated that 90 per cent of roof leaks are due to faulty flashing.

Different types of roof flashing protect different areas of the roof. But whatever type they may be, their main function is to redirect water away to prevent leak and damage. Roof flashing is applied to the corners and valleys of the roof, as well as to any object that projects outward from the roof.

Roof flashing comes in a variety of materials, such as:

  • Aluminium — a commonly-used flashing material. It is lightweight, durable, cheap and easy to apply. It is typically coated to protect it against corrosion.
  • Lead — soft and pliable, lead is one of the oldest flashing materials used for roofing. It is durable and often used for chimneys due to its reliable protection against water seepage. However, lead comes with health risks and is no longer used as often.
  • Copper/Lead Coated Copper — pliable, low-maintenance, solders well, and compatible with almost any wood preservatives, copper flashing is the most durable flashing material. It easily adapts to weather changes and lasts a long time, too.
  • Steel/Galvanised Steel — rust-resistant, easy to apply, and cheap, galvanised steel roof flashing is visually-appealing and can be painted on to meld with the rest of the roofing. It is not as durable a material, however, as others on this list. Thus, it is not recommended in regions with harsh weather conditions.
  • Plastics, Rubbers, and other Composite Materials — these are also cheap but may not be ideal for areas that experience extreme heat or cold. These can be made from recycled materials.

Certain building codes may require roofing professional to comply with specific standards for flashing. For example, flashing materials used must be manufactured in accordance with AS/NZS 2904. Check your local building codes to make sure your roofing system is compliant with the applicable regulations.

Different Types of Roof Flashing

How many types of roof flashing are there? Well, there is one type for every part of the roof — which is a lot! There’s even a flashing for flashing.  All the different types work together. Know more about the key types of roof flashing below:

Continuous/Apron Flashing

This flashing works like an apron between the roof slope and a vertical wall or roof penetration. It consists of a long piece of metal with expansion joints. Its purpose is to redirect water away and carry it down to the shingles.

Step Flashing

This consists of a rectangular metal bent at 90˚ in the centre for a roof-to-wall application. Protecting the transition spots between the roof and wall, this flashing is laid in “steps” — that is, in layers overlapping 2 inches. It redirects water into the gutter. If one layer fails to do its job, the one beneath it will carry on the task.

Base Flashing

Base flashing works with another flashing type, the counter flashing, to effectively seal the vertical and horizontal intersection of the roof. It is typically used for chimneys and walls or parapets. This flashing keeps water from penetrating the roof deck.

Counter Flashing

This flashing complements the base flashing and is entrenched into the masonry to prevent water from getting behind the base flashing. It is also known as cover flashing or cap flashing.

Drip Edging

Applied on a roof’s eaves, this flashing guards against the water seeping underneath the shingles in case of an overfilled gutter. Without it, water can get into your home and damage the roof deck, wood fascia board, drywall, and other roof parts.

Vent Pipe Flashing

This is a special flashing that has a cylindrical body with a flange at the bottom which is fitted over pipes. It prevents water from slipping around the pipes or flues.

Valley Flashing

Shaped like a V or W, valley flashing is placed atop the roofing felt where one of the most critical water leaks can happen — the roof valleys. The roof valley is where two segments of the roof meet forming a dip or a valley. This flashing type guides water down the roof and straight into the gutter.

Saddle Flashing

Also referred to as joist saddle flashing, this is placed over joists, beams, or other protrusions through the cladding.

Common Applications of Roof Flashing

Roof flashing is found all over the roof. These are the crucial areas where flashing is required:

  • Roof valleys and joints — there are prone to water penetration due to the angles that can easily collect water.
  • Roof protrusions — these are anything that juts out of the roof such as plumbing pipes, satellite poles, and dormers. Pipe boots fitted around the pipe can help keep water from slipping in.
  • Chimneys — flashing around chimneys prevents water from collecting and leaking at the base of the chimney.
  • Skylight — there are skylight installations that come with built-in flashing. Without it, roofing professionals purchase or create flashing for skylights, as this area can be notorious for leaks. Flashing for skylights typically consists of continuous flashing, step flashing, and finally, saddle flashing.
  • Roof edges — flashing around these areas help secure the roof against leaks by directing the water off the roof.
  • Kickouts — roofing professionals apply kickout or diverter flashing to reroute rainwater that falls at the lowest point of the joint between the roof and wall and into the gutter.
  • Roof ridge — flashing is applied to cover the roofing material. It secures the roof apex from water penetration due to rainwater falling at an angle.

When to Call for Professional Roof Flashing Service

Roof flashing is essential for weatherproofing every part of your roof that is vulnerable to leaks. Flashing also provides aesthetic appeal and creates a sharp, seamless finish on the roofing job. It is essential to pay attention to roof flashing during routine maintenance.

Over time, flashing can get damaged and may need replacement. If left unfixed, there may be serious water leak damage that can be quite costly to repair. When you notice signs of damage like holes, corrosion, dried out sealant, or flashing that has bent or come loose, it’s time for a roofing service.

5 Basic Gutter Maintenance Tips You Need To Do Now

5 Basic Gutter Maintenance Tips You Need To Do Now

Practical tips for residential property owners and tenants.

Basic gutter maintenance is not the most exciting topic of conversation for homeowners. Roof gutters, however, are a critical area in roof maintenance because they are one of the most vital pieces of roofing yet often the most neglected.

Whether you are a homeowner or a tenant, it’s crucial to prepare your gutters and give them the protection they deserve. Doing so will save you a lot of money and spare you from further inconvenience down the line. In this article, we list down some tips to follow to help preserve the general health of your gutters.

Roof Gutter Maintenance for Residential Property Owners and Tenants

Before going up and working on your roof and guttering, ensure the safety of the entire process. Bring all the right equipment and climb slowly. Many of these tips won’t be effective if you don’t practice appropriate safety protocols.

Always use a ladder going up and watch your step. If you’re not sure how to go about gutter maintenance, it’s best to hire roof specialists instead of risking your life. Plus, some roofing experts offer sound advice on keeping your gutter in tiptop shape according to your local conditions.

1.  Start with a gutter inspection.

Visual inspection is crucial to plan out your course of action throughout the maintenance process. Use a maintenance checklist if you have one and look out for any issues that may pose a bigger problem in the future.

Note any trouble spots you see and actively look for mould growth, rust, or deformation. Look for troublesome areas on your gutter that give you a hard time to clean.

Basic maintenance doesn’t entail deep cleaning and parts replacement; however, it needs a good eye to catch growing issues on your gutter. Common gutter problems include:

  • Clogging
  • Sagging
  • Leaks and holes
  • Improper pitching
  • Downspout problems
  • Joint separations
  • Improper slopes

Many of these problems can be addressed with basic cleaning and draining. Others, such as joint separations, are better resolved by gutter and roofing experts. If you notice any developing issues, it’s best to ask advice from your local roofing expert.

2.  Keep the gutters clean.

You need to keep your gutters clean to have effective water drainage on your roof. Clearing out any dirt and debris from your roof and gutters at the outset can help prevent blockages. These are especially important during the rainy season.

Australian summers are both the hottest and wettest periods in the country. November to April often bring a lot of wind and rain, and more rain means more activity for your roof and fewer chances to clean up. It’s best to clean your gutters during spring and fall. Early preparation can save you a lot of grief once bad weather conditions start.

Gutter blockages happen more often if you live in an area rich with trees. So, adjust your cleaning frequency depending on the size, number, and expanse of bush in your locale. Routine gutter maintenance can happen as often as four times a year, once at the end of every season. If your budget is limited, cleaning twice a year during spring and fall would work will also work wonders for your roofing.

3.  Wash and clear your downpipes.

Your next move is to check your gutter’s downpipes. The downpipes are the plumbing that drain water away from your gutters. These move water into the drains and prevent it from collecting on your roof or in your gutters.

Confirm that they are working by getting a hose and running water through your downpipes. It’s best to do so at the maximum setting when possible. If debris is stopping the flow of water, you need to clean the pipes.

If you have access to a pressure washer, use it to carefully spray the insides of the gutter. Using a big bucket of hot water can also force out any debris and blockages inside.

When doing this step, make sure that you have someone to assist you in basic gutter maintenance. Two extra hands keeping the ladder steady mean a whole world of safety for you.

4.  Look out for rusty gutters.

Another common issue in many Australian roofs is frequent rusting. Rust is typical where rain and heat are commonplace. The salt air in the beachside suburbs also accelerates oxidation of roofs.

Gutters made of galvanised steel or aluminium are strong and durable but can be prone to rust. These systems have protective zinc coating, but rusted gutters can be an issue once that wears out or is damaged.

If you find minor rusting during your gutter inspection, scrub it carefully with a wire brush. Keep the general area clean and free from dust, wash it off, and let dry. Once it’s dry, find a metal primer that helps inhibit rust.

Weatherguard paints and zinc-rich coatings can help keep your gutters healthy for a while. If you’re not sure how to do the job, ask roofing experts that can point you to the right supplies. Tell them about your situation and get free advice on what you can use.

5.  Install a gutter mesh.

A gutter mesh can help reduce the residue in your gutter by preventing leaves from falling into the actual gutter. By installing gutter mesh, you can cut your basic gutter maintenance by at least half.

However, even the best gutter mesh has limits to what it can do. Every make and model will allow some soot and silt to pass through. Too much dirt can result in the growth of weeds and grass in your gutter.

With the right gutter mesh, you can reduce gutter cleaning to once a year. In many cases, some excellent gutter mesh can cut cleaning every five years. Once a year, give your gutters a quick inspection for any potential issues.

Basic Gutter Maintenance is More Important than You Think

Basic gutter maintenance is a matter of persistence and consistency. Getting lazy and skipping a season or two of care can mean more repair expenses in the long run. However, not everyone has the right tools and roofing equipment to do the job. In this case, your best option is to hire a Sydney roofing specialist to help take care of your gutters periodically.

Sydney Roof & Building Supplies is your one-stop-shop for all your roofing and building supplies. We offer a wide selection of roof tiles, gutter mesh, and roof paints. If you’re unsure of what you need, SRBS has expert staff to guide you through the right decision.

Should I Install a Roof Vent?

Should I Install a Roof Vent?

Choosing among whirly birds, mains powered vents, and solar powered vents.

Ventilation allows air to flow within a space in your house through a system of intake and exhaust. By installing proper ventilation, you will be able to reduce your energy costs, regulate indoor temperature, and extend the life of your roof.

How does roof ventilation work?

Roof ventilation allows air to flow through the ceiling space to prevent overheating and excessive moisture.

There are two ways to create air flow within your roof space:

  1. Mechanical – requires a power source
  2. Natural – driven by the movement of air

Ever heard of the stack effect? This occurs when hot air rises and creates high pressure in top of a building. To allow hot air to escape, you must find a way for cool, low-pressure air to get in. The cool air that enters is called intake while hot air that escapes is called exhaust.

Meanwhile, wind effect occurs when the wind blows against the outside of a roof and generates the natural flow of air.

Benefits of installing a roof vent

In essence, proper ventilation allows the fresh air in and the stale air out. A well-ventilated attic will have bottom roof vents at the soffits or eaves (intake), and top roof vents at the peak or ridge (exhaust). With optimal air circulation, your attic space will have uniform temperature and humidity regardless of the season.

In order for roof ventilation to work effectively, there should be a balance between intake and exhaust.

Balanced ventilation means that the intake and exhaust allow the same amount of airflow as natural air pressure creates a push-pull effect around your roof. Without proper intake, air will only circulate across the top and leave stagnant air at the bottom. Without proper exhaust, hot air won't be able to escape.

It would help to have vents on both sides of the attic – similar to having windows on both sides of the house to allow the breeze to circulate.

What can a balanced ventilation do for you?

·  Improve air quality

As mentioned, roof vents replace stale air with fresh air which can help improve air quality in domestic settings, particularly in small spaces such as kitchens and laundries. In commercial and industrial environments, roof vents are even more beneficial as these spaces often contain fumes, toxic gases, grease-laden air, and corrosive vapours. Proper ventilation can remove all these elements and replace dirty air with clean air.

·  Keep cooling costs down

During a 90° summer day in Australia, hot air gets trapped in ceiling spaces with temperatures reaching 140° or higher. Without an exit, this hot air stays there. This increases the indoor temperature below, which forces your air conditioning, fans, and other cooling appliances to work harder.

Roof vents can help push hot air out and cool down the ceiling space in homes, warehouses, factories, and other structures. By taking the load off the air conditioning, roof vents contribute to lowering your cooling costs.

·  Prevent cold-weather condensation

Winter weather is a much tougher challenge for attics. When warm indoor air rises to a cold roof, it condenses into moisture. This can cause the roof deck to buckle, swell, and rot over time. Condensation also attracts mould and mildew, which can have a negative impact on indoor air quality and trigger allergies.

·  Eco-friendly and energy-efficient

Whirly bird roof vents harness the power of the wind to remove stale indoor air and replace it with fresh outdoor air. This makes them eco-friendly and energy-efficient.

·  Durable and long-lasting

Top-quality roof vents usually come with 10- to 15-year warranties. In some cases, they last even longer. Whirly bird roof vents are made of durable construction material, with some models built with fireproof mesh for homes that are located in bushfire-prone areas.

·  Easy to install

Roof vents are typically lightweight, so they are easy to transport and install for roof specialists. Here at Sydney Roof and Building Supplies, we offer flexible installation solutions to meet your exact ventilation needs.

·  Zero maintenance

Roof vents are designed to withstand harsh weather conditions and require little to no maintenance. Once installed, they work well with minimal human intervention.

Do you need a roof vent?

Modern Australian houses are built with roof cavities with plenty of insulation to keep them separate from the air-conditioned interior below. However, if your home does not have such an airtight ceiling, you can expect warm, moist air to find its way up to the roof.

Do you have a metal roof? Is your roof colour dark? These are likely to absorb more heat and release hot air into the rest of the house. A roof vent is exactly what you need to keep your roof cavity from getting too hot.

Types of roof ventilation

If your home is poorly ventilated, you have many roof vent choices to choose from.

1. Whirly birds

Conventional ventilation solutions can come with significant installation costs. They also require a power source, which means you are going to incur operational expenses. On the other hand, wind-driven roof vents – more popularly known as whirly birds – are not only cheaper but more far more effective in pushing air out of your roof.

2. Mains-powered roof vents

Mains-powered roof vents are significantly more costly than whirly birds and require a power source in the roof space. You will have to install a power outlet in the roof if you currently don’t have one.

3. Solar-powered roof vents

Solar-powered roof vents are almost as pricey as mains-powered roof fans upon installation, but they do not have operational costs as they rely on the sun for power.

Things to consider when installing roof vents

If you are considering installing roof vents, here are four things you have to consider before making a purchase:

  • Number of units – what do you need and how much do they each cost?
  • Ease of installation – can you do it yourself or do you have to pay someone else to install them?
  • Quality of installation – make sure they are watertight for your peace of mind during wet weather.

Generally, whirly birds are easy to install and most are suitable for installation on Australian roofs. Some mains-powered roof vents and solar-powered roof vents come with a variety of flashings that are designed for American roofs, this makes them difficult and time-consuming to install on tin and tile roofs in Australia.
