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.

If you aren’t sure what type of ventilation will fit your roof, give us a call at 02-8090-3483. Our roof specialists in Sydney NSW can tell you exactly what to look based on your location, roof type, and whether your roof is fully conditioned or thermally isolated.

The Importance of Insulating Your Roof

The Importance of Insulating Your Roof

Proper insulation can significantly impact your comfort, as well as the energy efficiency of your house. Australia has an extreme range of climates, and your residence should be prepared for scorching days as well as freezing ones.

During cold months, heat can be lost through your ceiling, and during the summer season, heat can penetrate your home through the roof. That’s why aside from insulating your floors and walls, you must also insulate your roof.

Types of Roof Insulation

There are different types of roof insulation for you to choose from. Your choice will depend on the type of roof that you have, the insulation that you need, and your budget too. Each comes with its own sets of benefits and drawbacks, so it’s vital to understand them before you decide.

·  Spray Foam Roof Insulation

Polyurethane spray foam, aside from helping you reduce a maximum of 20% off your energy bill, can also lower your carbon footprint. This type of insulation is applied directly to the slates of your roof, tiles, or roofing felt.

Spray foam roof insulation helps extend the life of your roof, provides acoustic insulation, and helps prevent pests from entering your loft space. This type of insulation, however, should be installed by a contractor.

·  Rigid Insulation Boards

If you are using your loft as an extra bedroom or as an attic, then you can use rigid roof boards for your insulation. These boards are placed between your roof rafters and are then covered with insulation plasterboards for a cleaner finish. The walls of your loft must also be insulated in the same way. Just make sure to keep the loft well-ventilated.

The use of rigid insulation boards with insulation plasterboards can be more costly than other types of roof and loft insulation.

·  Blanket Insulation

This type of insulation comes in rolls of foiled-backed felt or mineral fibre. One of the main benefits of blanket insulation is that you can apply it on your own. Of course, if you are not confident, you can always call a professional roof insulation installer.

·  Loose-Fill Insulation

Loose-fill insulation that is blown and installed in the gaps between your roof joists is the perfect choice for lofts that are not easy to access. Your professional roofer will use special equipment to blow loose and fire-retardant insulation materials. The loose insulation materials may be cellulose fibre, cork granules, mineral rock wool, or recycled newspapers.

·  Structural Insulated Panels

These refer to prefabricated panels that you can use to insulate your roofs. They provide better insulation than other insulation methods. Although you can add some insulation to existing structures, these panels are preferrable for new structures.

Benefits of Roof Insulation

Here are some benefits of insulating the roof of your home.

·  It makes your house more comfortable.

Your comfort is fundamental. Your home is a place of rest and relaxation, and the quality of your rest will depend on the comfort of your house. Your resident is a place that provides you with protection against extreme weather conditions. However, if your home is too cold or too hot, you sacrifice the quality of your sleep and rest.

Roof insulation can perform either heat retention or heat prevention. During the cold months, efficient roof insulation keeps the heat from escaping through the roof, keeping the interiors of your home cosy and warm.

During summer months, you want your roof insulation to do the opposite. Excess heat entering your home can make your home feel like a blistering oven, especially when the temperatures are soaring high.

If you want your home to be a comfortable haven, ensure that is well-insulated from the heat and cold.

·  It makes your home more efficient.

Efficient roof insulation keeps the temperature in your home more stable. This puts less work on your heating and cooling devices, allowing you to save on your utility bills. The initial cost of installing insulation can soon be rewarded with savings on your power bills. Some types of roof insulation materials can help you save up to 20% off your usual energy bills.

·  It helps extend the life of your roof.

Some roof insulation materials can help extend the lifespan of your roof and help reduce the need for roof maintenance. Spray foam, for instance, gives you a more stable roof. Roof insulation reduces the temperature within the structure during summer and keeps it dry and moisture-free as well. Consequently, this reduces the risks of moulds and mildew, which can affect the integrity of your roof.

Extreme temperature changes can slowly take its toll on your roof. A poorly insulated roof will be more susceptible to damage and you will end up with more costly repairs and replacements.

·  It helps make your home more sustainable.

Your house can be made more sustainable with proper insulation and ventilation. It will not be too dependent on heating and cooling equipment. Not only does this help you save on energy bills, but this also helps reduce pollution and carbon footprint. It’s the first step that you can take for a greener home and lifestyle.

·  It makes your attic liveable and more comfortable.

Without proper roof insulation, your attic will be unbearably hot or cold. With insulation in place, your attic becomes a more comfortable space that you can use. Instead of just a storage space, you can even convert it into an additional bedroom that you can still use for the children or your guests. It’s an efficient use of space that big families will appreciate.

Basic Roof Maintenance You Can Do Yourself

Basic Roof Maintenance You Can Do Yourself

These roof maintenance tips can help you save money now and in the long run.

Your home’s roofing protects you from different harsh environment conditions like heavy rains, strong winds, and extreme heat of the sun. Regardless of the season, your roof is exposed to extreme hazards that may cause damage if it’s not given the proper maintenance it needs. Neglecting these roof hazards may result in:

  • Corrosion
  • Denting
  • Scratching
  • Leaking

If not mitigated, you will be left with no other option but to replace your roof.

Fortunately, there are things you can do to maintain your roof without the cost and hazards. After all, hiring a roofer can result in exorbitant fees, and it might not be the safest right now given the COVID-19 pandemic. If you can take care of these issues yourself, you can avoid putting your roof and yourself in a dicey situation.

Here are some basic roof maintenance tips to keep in mind. Just a caution: always take appropriate safety measures in whatever you do! If in doubt, have a licensed roofing specialist do it for you.

Regular Roof Inspection

A regular roof inspection can be quite helpful in knowing the status of your roof and the potential problems that might eventuate. The roof’s surface can be damaged by several factors, such as exposure to the extreme heat of the sun, presence of water, and accumulation of debris falling from nearby trees.

It is imperative to check the gutters for shingle granules as these are an indication that your roof is starting to wear and needs extra care. You also need to check the roof for the presence of algae or fungi, which could cause damage to the roof if they remain overlooked.

A study on roof weathering revealed that algae commonly grows on the surfaces of roof materials, which include asphalt shingles, concrete and clay roof tiles, and even slate. Moss, lichens, and algae can all build up on a roof.

Metal roofs, on the other hand, are prone to rusting due to harsh weather conditions and the presence of elements like iron oxide. Rust may result in corrosion and can cause leaks that are detrimental to your home.

Washing Off the Damage-Causing Elements

Clearing off hazardous elements from your roof will surely extend its life. Common elements that find their way on to your roof include dirt, leaves and twigs, water, acid rain, and mould. These elements should be eliminated as soon as possible before they cause damage to your roof.

· Using water

You can use plain water to get rid of the accumulated dirt on your roof. You may use a bucket to splash water and wash off the dirt, or you can take advantage of your hose to make it easier for you. Using a hose can be awkward, but it is much more effective because the water pressure is stronger and controllable.

· Using detergents

Most people prefer using detergents on their roof because these materials are readily available in their homes. You can use mild laundry detergents and dish soap or other commercial detergents like those for cars. Just make sure they are mild as there are detergent types that can damage to your metal roof.

· Using solvents

Sometimes, water may not be enough to eliminate the hazards that accumulate on your roof. For tougher elements like oil, grease, tar, and rust, you can use solvents. But bear in mind that solvents should only be used to clean a portion of the roof. Avoid applying them to the whole roof as their strong chemical content could be dangerous to living things. Also, to protect yourself from harmful chemicals that come with these solvents, you must wear eye protection such as safety glasses.

Brushing the Gutters

Gutters are usually where debris like leaves, twigs, and algae accumulate. You have to regularly check the gutters to prevent them from clogging. Cleaning the gutters is something you can do yourself if you have the right tools.

Necessary tools like a brush and a ladder should be available at the hardware. Just place the ladder on one spot at a time, so you can start clearing the gutters of any debris.

Debris like twigs and leaves that collect in the gutter can block the waterway and prevent the water from going to the downspout. A high volume of water build-up could overflow on the gutter or come back up the shingles and down your house. It’s something you want to avoid.

Monitoring the Pipe Jacks

You have to pay close attention to your pipe jacks. A pipe jack is simply a flashing that sits at the base of any pipe that comes out of the roof. The flashing may start degrading over time due to harsh conditions. When broken, this can cause water leaks to enter through your roof.

Moreover, the rubber on the base of the pipe may start to contract and pull away from the pipe, which will cause leakage inside your house. It’s best to keep an eye on your pipe jacks to prevent further damage.

Check for Exposed Nail Heads

Nailheads are usually visible on your roof, especially on the flashings, at the bottom of the pipe jacks, or the ridges. Your roof is going to have exposed nails, especially on the flashings. These nail heads should not be exposed and should be sealed to prevent water from entering the shingles to the wood decking and your attic.

Use silicon coverage products to seal off these nail heads. You can find these products in hardware stores.

Keep Valleys Clean

A valley is where two downward-sloping roof pitches intersect. Although most modern houses do not have exposed valleys, some still do. Open valleys can accumulate twigs and debris that may cause clogging and rusting, so it is important that you clear out the valleys from time to time.

Check the Flashing and Seals on Skylights

Some houses have skylights that give natural light to a room. This part of the roof, however, is not immune to the accumulation of dirt and debris and also needs special attention. A skylight will have a flashing at the top and the bottom.

For the bottom part, you should check out the exposed nails and make sure that they are properly sealed off. The flashing along the side and the top of the skylight should be maintained well because this is where dirt and debris collects.

The seal between the frame of the skylight and the glass can degrade over time, which may cause water to enter through the roof. Check your skylight from time to time as you might need to have it resealed if the initial seal has degraded.

Most Common Types of Roof Damage

Most Common Types of Roof Damage

From water damage to cracks, tears and punctures, we explain briefly the common types of roof damage.

Many homeowners take their roof for granted. They spend for a kitchen renovation, a living room revamp, and even a garage overhaul. Almost always, however, they overlook the maintenance of their roof.

The roof is one of the most vital parts of your home. It provides you, your family, and your belongings protection from harsh weather conditions, and it keeps you safe and comfortable amidst extreme Australian weather elements. However, your roof is also the most exposed part of your home. If not taken care of, it can fall prey to significant damage, and before you know it, it could be too late and costly to repair.

Common Roof Damage to Look Out For

Being observant definitely pays. Here are the most common types of roof damage that you should look out for and address.

1.  Water Damage

Water damage is probably one of the most common roof problems, and one of the first symptoms of moisture damage is a leaky roof.

A leaky roof will leave discoloured spots on your ceiling which are actually mould rings. Worse, water damage can already be present even without these unsightly water spots and rings, and that is why roof maintenance is vital.

There are many reasons for a leaky roof, and that is why merely closing a hole in your roof may not be the right fix. It can inadvertently lead the water to another spot in your roof, thereby spreading the damage.

Any of the following can cause the leak in your roof:

  • Damaged shingles
  • Roof features such as chimneys or skylights
  • Valley damage
  • Failed sealants
  • Loose roof tile
  • Warped flashing

2.  Mould and Algae Damage

Allowing mould and algae to develop and grow can reduce the lifespan of your roof. Most residential roofs can last 20 to 50 years if maintained properly. Ignoring mould in your roof and taking no action can significantly damage the integrity of your roof.

Mould often has a distinctive smell and slimy appearance, but be aware that dry rot can be difficult to detect, and will usually look like black or dark green patches. Mould results from the presence of moisture or water.

Algae, which are usually greenish-black in colour, can eat away at your roof shingles. It is most common in your gutters where water is present. Humid and damp areas are common algae breeding grounds.

When left untreated, mould and algae growth can lead to more serious roof damage and leaks.

3.  Broken and Loose Shingles

Strong Australian winds can easily loosen your roof shingles, especially those that are have not been properly installed by a roof professional. Strong winds, in addition to damaging weak flashing, can blow off your shingles, leaving some sections of your roof bare and naked. It can tear off your shingles, warp them, lift them, or curl them up.

Debris from trees can also tear away your roof shingles. A major storm, hail, and extreme weather can wreak havoc on your roof. Damaged shingles can increase your chances of having a leaky roof, damaging the interior of your home, and making the repairs more complicated. It can also result in moulds and rot, which can affect the integrity of your roof.

4.  Cracks, Tears, and Punctures

The poor design of your roof can lead to cracks and splits. Careless roofing contractors or painters visiting your roof can cause tears and punctures. Debris from trees or those brought on by storms can also leave tears and punctures in your roof. Punctures caused by debris during a storm are all the more hazardous because heavy rainfall can bring serious leaks into your home.

Roof punctures are caused by sharp pressure that leaves a hole through your roof. What makes punctures and tears dangerous is that they are easy to miss. When left unchecked and unrepaired, they can let moisture seep in and cause further damage to the roof membrane.

Symptoms of Roof Damage

You may not think that your roof has a problem until you find the floor pooled with rainwater. It’s impractical and a little irresponsible to wait for the damage to be too much that a simple repair won’t be able to fix it. Be on the lookout for these early symptoms of roof damage. The sooner you can identify the damage, the sooner you can find and implement the right solution.

·    The roof leaks when it rains.

A leaking roof is probably the biggest giveaway that your roof is damaged and needs some tender loving care. Take even the smallest of leaks seriously as they can still get unwanted moisture in between your roof’s membranes. The deterioration of your roof can spread quickly if you ignore these tell-tale signs of roof damage.

·    Light comes through the roof.

Only holes of significant size can let the sun shine noticeably through your ceiling, but light will come in through even the smallest holes and even thin patches. This is one of the most obvious signs of roof damage, but also one that is most overlooked.

To check if your roof has holes, you need to get into the crawl space. Turn off all the lights, close all windows and blinds. If you still see some light in your ceiling space, your roof definitely has holes.

·    There are stains and discolouration in your ceiling.

Continuous leaking can result in some visible signs on your ceiling and walls. These drips of water take with them dust and dirt which can discolour the paint of your home’s interior. The stains can come in brown, grey, or yellow colour. They appear as unsightly circular rings on the ceiling and ugly streaks on your walls.

·    Your ceilings are sagging.

Water damage left unchecked can result in a sagging ceiling, which means a significant amount of water has pooled in the same area.

·    Your electricity bill is increasing.

Just as water can get in through the holes in your roof, air and heat can also escape through them. Your heating and cooling systems have to work overtime when there are temperature leaks. If your electricity bill keeps increasing, you might want to check your roof for holes.

Choosing the Right Paint for Your Australian Roof

Choosing the Right Paint for Your Australian Roof

What factors to consider when choosing your roof paint and how to make sure you have covered all your bases

The weather in Australia can be quite harsh on rooftops at times. A great example would be the extreme weather patterns that Sydney experiences fairly regularly including conditions such as acidic breeze, hailstorms, torrential rains and heatwaves. For that reason, it makes sense that choosing the right materials is essential to maintain your house’s structure and appearance, and that definitely includes roof paint!

Roof painting involves many more considerations than just choosing a new look or style for your home and If you’re at a loss on where to start, here are some tips to guide you through the process of selecting the right roof paint for your home

Check the material of your roof

Roofs are made from different materials, and the most common materials are concrete, colourbond and corrugated iron or metal. It’s important that you know what the type of roof you have is because it may not be compatible with the paint you choose.

·   Concrete Tile Roofs

Concrete tiles on roofs do not necessarily need painting for structural reasons, however it’s certainly done now and then - especially during remodelling or for styling reasons. It requires a clear alkyd primer to form an acceptable bond between the surface of the tile and the new coating. We recommend using a high-quality 100% acrylic paint afterwards to finish the job.

·   Colorbond roof

Painting a colorbond roof is not as easy as painting concrete tile roofs. The process is entirely different, and a multi-layer coating system is needed to produce a sleek and long-lasting finish.

Some colorbond roof paints are self-priming, but you can still use a primer to make sure that the application of paint is even just to be extra sure. Using an airless spray gun can help for better adhesion and smooth application of the primer.

Colorbond roof paints are made out of a specialised water-based acrylic membrane, which can only be applied using an airless spray gun for an even finish. It needs at least two coats before allowing it to sit properly.

·   Corrugated iron and metal roof

Don’t just choose any paint for a corrugated iron and metal roof. Instead, look for an acrylic-based paint for “exterior use”. In addition, acrylic latex paint functions well, especially if the roof is relatively brand new and not suffering from wear and tear.

You can also use oil-based alkyd paint and pair it with a suitable galvanised metal primer. However, a topcoat does not remove the need for a primer. The topcoat will secure the paint, but the primer will make the paint adhere effectively.

Stay away from lead

No matter the case, always stay away from paints that contain lead as their main component. Lead-based paints are not allowed in many areas and they also pose health hazards for you and your family.

Exposure to high amounts of lead may result in weakness, anaemia, and brain and kidney damage. Lead can also cross the placental barrier, so if a pregnant woman in your family is exposed, her unborn child becomes at risk. Safer choices include titanium dioxide and acrylic paint.

Consider the type of protection you want for your roof

There are now many innovative roof paints available on the market that address the various concerns of homeowners. Try to narrow down what kind of protection you want for your roof to help in the process of choosing the type of paint you want.

  • Climate change caused an increase in temperature in many parts of the world. Added to this fact is that Australia is one of the countries that receive the most sunlight every year.
  • If you want to control the heat and the costs for air-conditioning, a heat-reflective roof paint might be a good idea. The paint has the ability to eliminate solar heat even before it enters your home. It will also protect your roof from corrosion and thermal shock. A heat reflective roof also increases the value of your house.
  • If you’re in the part of Sydney that experiences hailstorms and heavy rains, a waterproofing paint might work for you. There are different types of waterproofing paints, the most common of which is Masonry paint and acrylic paint.

Masonry paint can be used for almost all types of roof. It also quickly absorbs liquid solutions such as chemicals and water, and does not allow rainwater to penetrate your roof which makes it durable and dirt-resistant as well.

On the other hand, using acrylic paint with a primer increases your roof’s resistance to water. It is non-toxic, odour-free and quick drying.

  • If corrosion is a concern, look for a paint that works well with a primer that has anti-corrosive properties.
  • Some paints also offer other benefits like fire resistance or ability to repel pests and insects. With so many options available, choose the paint which makes sense for your needs.

Take time in selecting the colour of your roof paint

It’s easy to get too excited about choosing the colours for your chosen roof paint and overlook the functional factors that need to be thought about! There are other things you need to take into consideration when it comes to roof colour such as:

  • The colour of your roof can change the temperature of your attic by 20-40 degrees. It will have a massive impact on the cooling or heating costs of your home.

Light colours deflect sunlight and help keep the temperature low in a hot climate. On the other hand, dark colours absorb heat and help you to stay warm in cold a climate.

  • You might also want to check how your roof colour will affect the overall look of your home. For instance, a black or dark grey would likely match well with a blue or grey house. A brown roof goes well with a tan, cream or brown-coloured house. Dark colours can also make your house look smaller, while light colours do the opposite.

Choosing the correct type of paint will enable you to save a lot of money in the long run. You’ll save yourself from costly maintenance and repair expenses and although it’s tempting to do everything by yourself, it’s best to seek the help of a professional roofer for this type of task.
