Roof Flashing – How important is it?

When most homeowners think about their roof, they picture tiles or metal sheets protecting their homes from heavy rain and roof leaks. But the real protection against roof leaks often comes down to something far less visible — roof flashing.

If it is installed incorrectly (or starts to fail), water can enter your roof cavity and cause serious structural damage long before you notice a ceiling stain.

Here’s why proper roof flashing is one of the most important parts of your roofing system.

What Is Roof Flashing?

Roof flashing is thin metal (usually Colorbond®, zincalume, aluminium, or lead) installed in vulnerable areas of your roof to direct water away from joints and seams.

It’s typically installed around:

• Chimneys
• Skylights
• Roof valleys
• Wall-to-roof junctions
• Plumbing vents
• Dormer windows

These are all areas where water naturally collects or changes direction — and without flashing, they are prime leak points.

Why Proper Flashing Installation Matters

1. Prevents Water Penetration

Even the highest-quality roofing materials can’t stop water from entering small gaps where surfaces meet. Flashing acts as a waterproof barrier, guiding water safely into gutters instead of into your ceiling cavity.

Poorly installed flashing can:

• Lift during storms
• Rust prematurely
• Separate from surfaces
• Allow capillary water entry

2. Protects Your Roof Structure

A small leak around flashing can lead to:

• Rotten timber battens
• Rusted roof sheets
• Damaged insulation
• Internal plaster damage
• Mould growth
• By the time water stains appear inside your home, the damage may already be significant.

3. Extends the Life of Your Roof

Flashing is often the first component to fail on a roof. Proper installation and quality materials can extend the lifespan of your entire roofing system by years — even decades.

Professional roof plumbers ensure:

• Correct overlap and sealing
• Proper expansion allowances
• Secure fixing to prevent wind lift
• Compatible materials to avoid corrosion

Common Roof Flashing Problems We See

Some of the most common issues include:

• Rust and Corrosion – Older galvanised flashing can deteriorate over time, especially in coastal areas.
• Incorrect Installation – DIY jobs or inexperienced trades can leave gaps, poor sealing, or incorrect overlaps.
• Movement and Lifting – Thermal expansion causes metal to expand and contract. If not installed properly, flashing can loosen.
• Storm Damage – High winds and heavy rain can dislodge poorly secured flashing.

Why You Should Hire a Licensed Roof Plumber

Roof flashing isn’t just about placing metal around a joint. It requires knowledge of:

• Roof pitch and water flow
• Material compatibility
• Weatherproof sealing techniques
• Local building codes

A qualified roof plumber ensures flashing is installed to withstand harsh weather and protect your home long-term.

Attempting DIY flashing repairs often leads to temporary fixes — and bigger repair bills later.

Signs Your Roof Flashing May Need Repair

Contact a licensed roof plumber if you notice:

• Water stains on ceilings or walls
• Damp smells in roof spaces
• Rusted or visibly lifted metal around roof penetrations
• Leaks during heavy rain
• Debris buildup in roof valleys

Early repairs are significantly cheaper than structural roof restoration.

Protect Your Home with Professional Roof Flashing Installation

Flashing may not be the most visible part of your roof — but it’s one of the most important.

Investing in proper installation and timely repairs protects your:

• ✔ Roof structure
• ✔ Insulation
• ✔ Internal ceilings and walls
• ✔ Home value

If you suspect flashing issues or want a professional roof inspection, contact our team at Belmont Roof Plumbing today. A small preventative repair now could save you thousands in water damage later.

The Pros and Cons of a Metal Roof vs. Tiled Roof

When it comes to choosing the right roofing material for your home, two popular options often stand out: metal roof and tiled roof. Each has its unique set of advantages and disadvantages that homeowners should consider before making a decision. In this blog post, we’ll explore these pros and cons to help you make an informed choice.

Metal Roofs

Advantages:

1. Durability: Metal roofs are known for their exceptional durability. They can withstand extreme weather conditions such as heavy rain, strong winds, and even hail.
2. Longevity: A well-installed metal roof can last 40-70 years, significantly longer than many other roofing materials.
3. Energy Efficiency: Metal roofs reflect solar radiant heat, which can reduce cooling costs by 10-25% during the summer months.
4. Low Maintenance: Metal roofs require minimal maintenance compared to other roofing materials. They are resistant to mould, mildew, and insect infestation.
5. Eco-Friendly: Most metal roofs are made from recycled materials and are 100% recyclable at the end of their life cycle.

Disadvantages:

1. Cost: The initial installation cost of a metal roof is typically higher than that of other roofing materials.
2. Noise: Without proper insulation, metal roofs can be noisy during rain or hailstorms.
3. Expansion and Contraction: Metal roofs can expand and contract with temperature changes, potentially leading to issues if not properly installed.
4. Aesthetic Concerns: Some homeowners may not like the industrial look of metal roofs, although modern designs offer more aesthetic options.

Tiled Roof

Advantages:

1. Aesthetic Appeal: Tiled roofs offer a classic and elegant look that can enhance the curb appeal of a home. They come in various styles, colors, and materials, including clay, concrete, and slate.
2. Longevity: Tile roofs can last 50-100 years with proper maintenance, particularly clay and slate tiles.
3. Fire Resistance: Tile roofs are highly fire-resistant, providing an added layer of safety.
4. Insulation: Tile roofs offer excellent insulation, helping to keep homes cooler in the summer and warmer in the winter.
5. Low Maintenance: Like metal roofs, tiled roofs are relatively low maintenance and resistant to rot and insect damage.

Disadvantages:

1. Weight: A tiled roof is significantly heavier than metal roofs, which may require additional structural support for your home.
2. Cost: Similar to metal roofs, the initial cost of a tiled roof can be high, especially for materials like slate.
3. Fragility: While durable, a tiled roof can be brittle and may break if walked on or struck by heavy objects.
4. Complex Installation: Installing a tile roof is more complex and time-consuming, often requiring specialised labor.

Both metal and tiled roofs have their own sets of advantages and disadvantages. Metal roofs offer durability, energy efficiency, and low maintenance, but they can be costly and noisy. Tiled roofs provide aesthetic appeal, longevity, and excellent insulation but are heavier and may require more complex installation. Your choice will ultimately depend on your budget, aesthetic preferences, and the specific needs of your home.

When deciding how to do a metal roof repair, maintaining a sturdy and leak-free roof is the primary goal and is essential for safeguarding your home and belongings. When faced with roof damage, the decision to tackle the repair yourself or hire a professional can be challenging. DIY roof repair might seem like a cost-effective option, but there are significant factors to consider before making your choice.

The Pro’s of DIY Roof Repair:

1. Cost Savings: The most apparent advantage of DIY roof repair is the potential to save money. By eliminating labor costs, you can save money and only have to purchase materials.

2. Sense of Accomplishment: Successfully fixing your roof can provide a sense of achievement and self-reliance. It allows you to take charge of your home’s maintenance.

3. Flexibility: With the right skills and tools, you can address minor issues at your own convenience, without having to wait for a professional’s availability.

The Con’s of DIY Metal Roof Repair:

1. Safety Concerns: Roof work is inherently dangerous, involving heights and unstable surfaces. A lack of proper safety equipment and training could lead to accidents and injuries.

2. Skill and Knowledge: Effective roof repair demands a deep understanding of roofing materials, local building codes and roofing trade knowledge. Incorrect repairs might exacerbate the problem, leading to more expensive fixes down the line.

3. Time-Consuming: Roof repairs often take longer for beginners than for experienced professionals. This could leave your home exposed to the elements for an extended period.

Professional Metal Roof Repair:

1. Expertise: Roofing professionals possess years of experience and training, ensuring that they can accurately diagnose issues and implement effective solutions.  At Belmont Roof Plumbing, Daniel has over 20 years experience working in the roofing industry.

2. Quality Materials: Professionals have access to high-quality materials and tools that may not be readily available to homeowners.

3. Time-Efficiency: Hiring professionals can result in quicker repairs, minimizing the risk of further damage to your home.

Considerations when Choosing:

1. Severity of Damage: For minor issues like small leaks or missing shingles, DIY repair might be feasible. However, extensive damage, such as widespread leaks or structural problems, necessitates professional intervention.

2. Safety Precautions: If you’re uncomfortable with heights, lack proper safety gear, or have limited experience, it’s safer to leave roof repair to the experts.

3. Budget: While DIY might seem cost-effective initially, poorly executed repairs can lead to greater expenses in the long run. Weigh the potential costs against hiring a professional.

4. Insurance and Warranty: Some DIY repairs might void your roof’s warranty or insurance coverage. Professionals often offer warranties for their work, providing peace of mind.

In the DIY roof repair vs. professional roof repair debate, the decision ultimately hinges on the complexity of the issue, your skills, and your comfort level with the associated risks. While DIY repair might be suitable for minor problems, entrusting your roof to skilled professionals ensures the job is done efficiently, safely, and to the highest standard. Prioritize the safety of your home and your own well-being, and carefully evaluate your options before making a choice. After all, a well-maintained roof is an investment in the longevity and value of your property.

Tradies are required to hold current licenses for good reason – they have been appropriately trained and are aware of any changes to Codes and Standards. Plumbers, drainers, gasfitters & electricians are all deemed specialist tradespeople.  Therefore, home renovators should never attempt to take on any plumbing, draining, gas fitting or electrical wiring work themselves.  It is illegal to carry out this type of work without holding the appropriate contractor licence due to the high risk of harm to themselves and others. So always ensure that you use a licensed plumber for this high risk specialist work no matter how small the job may seem.

Checking your metal roof in the winter is a vital part of home maintenance that often gets overlooked. The colder months can be particularly harsh on roofs with chilly temperatures, rain and wind putting your metal roof to the test. Taking the time to inspect your roof during winter can help you catch any issues early on and prevent costly damage down the line.  Look for any signs of damage such as rust, loose panels, or missing fasteners.  Clear any debris or build up that you find to ensure proper water drainage.

It’s also a good idea to check the space under your roof for any signs of leaks or water damage. Look for water stains, mould, or mildew, which can indicate a problem with your roof.

If you’re not comfortable inspecting your roof yourself, consider hiring a professional to do the job. A roof plumber can provide a more detailed assessment and recommend any repairs or maintenance that may be needed.

By taking the time to check your metal roof in winter, you can ensure that it remains in top condition and protect your home from the elements and prevent any roof repairs down the track. Stay proactive and address any issues promptly to keep your roof looking great and functioning properly for years to come.

Salt air, sun, and sea sounds like the perfect Summers day but it can also mean harsh treatment for oceanfront houses.  This cocktail of environmental conditions may cause roofing materials to rust out prematurely and potentially cause a major roof leak to your home.

We have attended numerous jobs in Torquay, Barwon Heads and Anglesea lately.  Rust is a common issue on the flues and metal brackets that hold gutters and downpipes.  In the case below in the photo, the flue cowl had completely rusted off and was missing from the roof entirely.  Being so close to the ocean, this rust issue is an all to common occurence with metal fixtures.

If you live in a coastal area and have a metal roof on your house, it is important that your roof does not hold onto any water.  This means ensuring the pitch on your roof is high enough for water to run off and not pool or hold any water.  Water that pools on your roof will accelerate the rusting process and potentially lead to costly repairs sooner than you anticipated.  A great alternate to metal down pipes is to use PVC downpipes.  These are commonly used in coastal areas and will not rust.  PVC downpipes come in white and can be painted to suit the colour of your home.

We provide a wide range of roofing services to Geelong and surrounds to protect your home or building from damage.  So if you have a problem with your metal roof, call and ask a licensed Roof Plumber about it today!

When working on the metal roof, gutters and downpipes of your home, care has to be taken to prevent early corrosion of materials which can lead to internal damage to your home from roof leaks.

All metal roofs will breakdown eventually.

When exposed to the elements, the steel along with rain and oxygen will eventually result in a rusted out roof.  However, with the average life expectancy of a metal roof being 70 years, there are a few key measures that must be factored in when installing a new roof or maintaining an existing roof to maximise its life.

Accelerated corrosion

This can occur when gutters are installed incorrectly with insufficient fall for the water to run away.  This results in water pooling.  If the metal gutter is constantly exposed to water pooling the steel will eventually rust and holes will form where the water pool was allowing water to filter through below.  Your licensed roof plumber should allow adequate fall on all your gutters to allow the water to run freely through the gutters and away from your house.

Accelerated corrosion can also occur by electrolysis when non compatible materials mix.  This is a phenomenon also known as galvanic corrosion.  And it is because of this that care must be taken to ensure the correct materials are used.  For example lead and copper should not come into contact with a Zincalume or Colorbond roof, and any water run off from copper or lead pipes should be avoided aswell.  There are no issues with zinc in combination with metals other than copper and mild steel.  When zinc contacts copper in the presence of an electrolyte (such as water) a galvanic reaction will lead to corrosion of the zinc and subsequent failure of the roof or wall cladding.  Run-off from a copper surface to a zinc surface must be avoided under all circumstances.  Zinc in contact with mild (carbon) steel is not desirable, either, due to similar electron transfers between the metal that will result in zinc corrosion and deterioration.

Summary

In general, water should not be allowed to run from a higher potential metal to a metal with a lower one. All metals should be installed in the following order (from top to bottom).

• Aluminium
• Zinc
• Galvalume
• Lead
• Copper

We recently attended a job where a lead flashing was installed on top of a zinc corrugated iron roof.  As you can see from the pictures below, this has resulted in the accelerated corrosion of the zincalume roof where the led flashing was.  This resulted in a roof replacement for the owners of the house in order to fix the roof leak and remove all the rusted out materials.

As Autumn sets in, it’s important to prepare your home for the cooler and wetter months ahead. One crucial area that needs attention is your roof plumbing. To help you get started, here are some roof plumbing tips for autumn in Australia.

Colorbond Roof

1. Clean your gutters and downpipes

One of the most important things you can do to prepare your roof for autumn is to clean your gutters and downpipes. Leaves and debris can clog your gutters and prevent water from flowing freely. This can cause water to overflow and damage your roof and the surrounding areas. You should also check that your downpipes are clear and free from any blockages.

2. Inspect your roof for damage

Autumn is the perfect time to inspect your roof for any damage that may have occurred over the summer months. Look for any missing or cracked tiles, as well as any signs of wear and tear. You should also check your flashing and seals to ensure that they are secure and watertight.

3. Check your roof vents

Roof vents play an important role in keeping your home well-ventilated and free from moisture. However, they can also become clogged with debris and leaves, which can reduce their effectiveness. Make sure to clear any debris from your roof vents and check that they are functioning properly.

4. Repair any leaks

If you notice any leaks or water damage in your home, it’s important to address them as soon as possible. Leaks can cause serious damage to your home and can be costly to repair if left unchecked. Make sure to hire a professional roof plumber to identify and repair any leaks.

5. Prepare for storms

Autumn can bring some severe weather, including heavy rain and storms. To prepare your roof for these conditions, you should make sure that it is structurally sound and able to withstand high winds and rain. Consider installing stormwater systems and other protective measures to help prevent water damage.

Taking care of your roof plumbing during autumn is crucial to maintaining the integrity of your home. By following these tips, you can ensure that your roof is in good condition and ready for the cooler and wetter months ahead. Remember to always hire a professional roof plumber if you are unsure about any aspect of your roof maintenance.
