Usually placed around the transitional areas of a roof, the flashing keeps a roof waterproof and airtight. Many people tend to ignore this important component of their roofing system or even install it improperly. The transitional or intersection areas where flashing is placed include the skylight, chimney, valleys, edges, joints, and more. Without proper sealing around these areas, your roof is susceptible to serious leaks.
Understand that the intersections and transitional areas on your roof often expand and contract with respect to the changing humidity and temperature levels. The flashing, therefore, plays a significant role in allowing for variable movement around these areas while protecting your roof from moisture. Basically, the flashing protects a roof from water damage and leaks.
The Purpose of Roof Flashing
As mentioned, without a flashing fitted on different areas of your roof, moisture and rainwater would run into your home’s interior after running down the chimney and other areas of the roof tiles. The main purpose of this is, therefore, to maintain a waterproof and airtight roof.
Without a flashing fitted into the roof valleys of your home, rainwater from both sides of the roof would simply flow into your house.
Always remember that your home’s exterior walls and some parts of your roofing system are prone to water damage and leaks. Any area of a roof that experiences heavy runoff and where opposing surfaces intersect or meet need the extra protection that it provides.
Materials Used for Roof Flashing
Due to technological advancements, homeowners can choose from a wide range of effective flashing materials at affordable prices. Materials used to make this include stainless steel, copper, lead, aluminum, plastic, and composite materials.
Copper is a preferred choice due to its malleability, high-resistance to elements, strength, and appearance. It’s, however, important to note that metal sheet flashing is the most expensive. The less costly option is plastic, though it can wear down faster as a result of exposure to sunlight.
Fitting a Roof Flashing
Without a properly installed and fitted flashing, it matters little how much your roofing materials cost and how nice it looks. Your roof will be vulnerable to water damage since rainwater will have access to your roof. This will bring down your ceiling and result in other serious problems. It’s, therefore, important that you hire an experienced roofer in Charlotte to properly fit your roof.
When installing a new roof on a home, roof flashings will be fitted before tiling the roof. However, when it comes to replacing damaged or missing flashing, in the roof valleys, the roofer will remove about 2 to 3 lines of tiles so he can easily remove the old valley flashing before fitting the new one.
It can get damaged as a result of improper installation, poor repairs, poor installation, age, and weather-related issues. If you notice any problems with your flashing, be sure to schedule a roof inspection and repair.
