Flashing is vital to prevent from entering your attic space through joints and seams in a roof, which can cause significant damage over time.
Traditionally, lead flashing has been the go-to material. But in recent years, there has been a shift towards more sustainable and safer alternatives, like Wakaflex, a lead-free solution.
What Is Wakaflex?
Wakaflex is a flexible flashing material made from an alternative to lead or metal flashing, like aluminium. Like all flashing types, Wakaflex seals roof joints, valleys, chimneys, and other vulnerable protrusions on your roof securely to prevent water from leaking into your home.
Wakaflex is made from a combination of synthetic rubber and other materials to mimic the benefits of lead flashing while being more lightweight and easier to handle. It's widely used and suitable in both residential and commercial roofing due to its versatility, durability, and compliance with environmental and safety standards.
It's available in a range of colours, but the main advantage of Wakaflex is that it's free from lead, making it a safer and more eco-friendly option.
What Are the Benefits of Wakaflex?
Wakaflex is an increasingly popular option among Australian homeowners. Here's why...
-
Alternative to Lead
Lead has long been used in roofing flashing as it's a malleable and durable material, but it poses environmental and health risks. While lead flashing is safe when fixed on the roof, it can be toxic to handle when installing or removing it.
Wakaflex is made of synthetic materials rather than lead, making it a safer choice for homeowners and roofers alike.
-
Easy to Install
Unlike traditional lead flashing, Wakaflex is incredibly easy to install. Its flexible nature means it can be moulded around complex roof shapes without the need for specialist tools, making it a great option for DIY enthusiasts as well as professionals.
-
Durable
Wakaflex is highly durable and can withstand the harshest weather, from heavy rain and snow to UV rays. It's also resistant to temperature fluctuations, meaning it's unlikely to crack or degrade over time.
-
Low Maintenance
Once installed, Wakaflex requires little to no maintenance. Its robust design ensures that it will provide reliable protection for many years without the need for frequent repairs or replacements.
-
Aesthetic Appeal
Wakaflex comes in a range of colours, allowing it to blend seamlessly with the rest of your home, whether you have slate, tile, or metal sheets. Its appearance is similar to traditional lead flashing, offering a clean and professional finish.
-
Environmentally Friendly
Lead is a toxic metal, and disposing of it can be harmful to the environment. Wakaflex, on the other hand, is made from recyclable materials and is a more sustainable choice for eco-conscious homeowners.
What Are the Drawbacks of Wakaflex?
Like all roofing materials, there are cons as well as pros. Learn what the limitations of Wakaflex are before making your decision.
-
Upfront Cost
Although Wakaflex offers long-term benefits, it may have a higher initial cost than traditional lead flashing. The price can vary based on the size and brand, but many homeowners find the long-term durability and low maintenance to be worth the investment.
-
Limited Lifespan
While Wakaflex is highly durable, it may not last as long as lead flashing. Lead flashing can last for several decades, whereas Wakaflex typically has a lifespan of 15-20 years, depending on your local environment and how well you look after your roof. However, this is still a good lifespan when compared to other alternatives – and well worth the cost.
-
Not Suitable for All Applications
Wakaflex may not perform as well as lead, particularly in extreme weather conditions or high-traffic areas. While it's versatile in many situations, lead flashing offers robustness.
What Tools Do You Need to Install Flashing
Installing Wakaflex flashing is a relatively simple process – here's what you'll need:
-
Measuring tape
-
Utility knife
-
Roofing nails or screws
-
Hammer or drill
-
Rubber mallet
-
Caulking gun
-
Sealant
How to Install Wakaflex Lead Flashing?
Proper installation will mean longer-lasting flashing. Here's how to do it yourself:
-
Measure the Area
Before beginning, measure the length and width of the area where the flashing will be installed – around a chimney, a valley, or joints on the roof.
-
Prepare the Surface
Clean the area – remove any debris, old flashing, or dirt to ensure that the Wakaflex will adhere properly. You can use a wire brush or a cloth to clean the surface.
-
Cut the Flashing
Use a utility knife to cut the Wakaflex flashing to fit around complex roof angles or shapes. Leave a small overhang at the edges to ensure full coverage and proper sealing.
-
Position the Flashing
Lay the flashing in position to cover the area properly. Press it down gently to mould it to the shape of the roof. For a tight seal, you can use a rubber mallet to gently tap the flashing into place.
-
Secure the Flashing
Using roofing nails or screws, secure the flashing in place, about 10-12 cm apart along the edge of the flashing.
-
Seal the Edges
Once the flashing is in place, apply the sealant around the edges of the flashing to create a watertight seal. Use a caulking gun to apply the sealant and smooth it with a putty knife or your finger.
Maintaining Wakaflex Lead Flashing
Wakaflex is a low-maintenance material, but regular inspection and upkeep can prolong its lifespan.
-
Inspect annually, checking the flashing for any signs of damage, such as tears, cracks, or lifting.
-
Clean the flashing, keeping it free of debris to prevent dirt, moss, or algae from building up, which can degrade the material over time.
-
Reapply sealant. Over time, the sealant around the edges of the flashing may begin to break down. If you notice any gaps or leaks, reapply the sealant to ensure a watertight seal.
-
Periodically check the nails or screws securing the flashing. If any fasteners are loose, tighten or replace them to ensure the flashing stays in place.
Final Thoughts on Lead-Free Roofing Solutions
Wakaflex is easy to install, highly durable, and ensures a watertight seal on your roof, and it's becoming a popular choice for homeowners looking for a lead-free alternative.
While it may not last as long as lead flashing, its many benefits make it a worthwhile investment for most roofing applications. Plus, with proper installation and maintenance, Wakaflex will be reliable for decades.
