No one wants to think about their roof failing, but sometimes disaster strikes. When it does, it’s essential to have quality roof flashings to protect your building. Roof flashings are vital in preventing water from seeping into your building.
Here’s what you need to know about choosing the right roof flashings for your needs.
The Different Types of Roof Flashings
There are three main types of roof flashings: metal, plastic, rubber, and asphalt. Each type has unique benefits and drawbacks, so choosing the type best suited to your specific needs is essential.
See below for more information:
- Metal Flashings: Metal flashings are made from materials like aluminium or stainless steel, known for their durability and long lifespan. Metal flashings are also fire-resistant and easy to install, making them famous for many commercial buildings. However, they can be expensive and are not as flexible as other types of flashings, making them more susceptible to wind or other elements damage.
- Plastic Flashings: Plastic flashings are made from materials like PVC or TPO, offering several advantages over metal flashings. Plastic flashings are less expensive than metal flashings and more flexible, making them less likely to be damaged by wind or other elements. However, plastic flashings are less durable than metal flashings and have a shorter lifespan.
- Rubber Flashings: Rubber Flashigs offer many of the same benefits as plastic flashings. Rubber flashings are less expensive than their metal counterparts while still being just as durable, if not more so in some cases. The material is also somewhat flexible, making it ideal in windy or high weather conditions where things may shift or bend. One drawback, however, is that rubber can degrade in direct sunlight, so keep an eye on these if installed in an area that receives a lot of sun throughout the day.
How to Choose the Right Flashing for Your Building
Now that you know the different types of roof flashings, how do you choose the right one for your building? The answer depends on several factors, such as the climate, the type of building, and your budget.
- Climate: If you live in an area with extreme weather conditions, like high winds or very cold winters, you’ll want to choose a flashing that can withstand those conditions. Metal flashings are an excellent option for high winds, while rubber or plastic flashings may be better suited for cold weather conditions.
- Building type: The building you have will also play a role in choosing the right roof flashing. Metal flashings are an excellent option for a commercial building because they’re fire-resistant and easy to install. If you have a residential building, you may want to choose a less expensive option, like plastic or rubber flashings.
- Budget: Obviously, your budget will also be a factor in choosing the proper roof flashing.
How to Determine if you Need new Roof Flashings
A few key signs indicate it’s time for new flashings, including leaks around the roof’s edge and rusted or loose flashings. If you notice any of these signs, it’s time to call in a professional to assess the situation and recommend the best course of action. Taking care of your roof can safeguard your investment and ensure that your building can withstand the elements for years.
Factors That Can Damage Your Roof Flashing
There are a few factors that can damage your roof flashing, including:
- Wind: High winds can cause the flashing to lift and blow away, leaving your roof vulnerable to water damage.
- Snow and ice: Snow and ice can cause the flashing to crack and break, leaving your roof vulnerable to water damage.
- Sun: The sun can cause the flashing to fade and become brittle, making it more susceptible to wind and water damage.
- Tree limbs: Tree limbs can fall on the roof and damage the flashing, leaving your roof vulnerable to water damage.
- Animals: Animals can gnaw on the flashing, causing it to break and leaving your roof vulnerable to water damage.
Regularly check your roof for damage if you live in an area with high winds, snow, or ice. If you see any cracks or breaks, it’s time to replace the flashing.
How to Properly Install Roof Flashings
Here are some tips for proper installation of roof flashings:
- Flashings should be installed over the entire length of the roof edge, from eave to ridge.
- They should be securely fastened to the roof deck with nails or screws.
- Flashings should be lapped at least 2 inches over the course below them.
- All seams and joints in the flashings should be sealed with caulk or another suitable sealant.
By following these simple tips, you can help to ensure that your roof flashings are correctly installed and will provide lasting protection for your roof.
Maintenance Tips for Your Roof Flashing
Once your roof flashings are installed, maintaining them is crucial to ensure they last. Here are a few tips for keeping your roof flashing:
- Inspect the flashing regularly: Look at the flashing every few months to ensure that it’s in good condition. If you see any cracks or breaks, it’s time to replace the flashing.
- Clean the flashing regularly: Use a putty knife to remove any debris from the surface of the flashing. This will help prevent the formation of rust and corrosion.
- Apply sealant regularly: Use a putty knife to apply a bead of sealant around the perimeter of the flashing. This will help prevent water from seeping through the cracks and breaking the seal.
- Repair any damage immediately: If you see any damage to the flashing, it’s vital to repair it immediately. Otherwise, water could enter your building and cause significant damage.
If you follow these tips, your roof flashings will last many years.
