Roof flashings are fittings that are set in place to keep water from flowing through the cracks that develop between your roof and various other installations, such as a skylight, a dormer window or a chimney. While many other areas of your home might have flashings – including your porches, walls, doors or windows, the roof flashing is the most common, since its role is the most crucial to maintaining the structural integrity of your home. The Wichita roofers at Penney Construction take pride in great installation of roof flashing, knowing it is the most important part of your home’s roof.
A roof flashing ensures that all joints between your roof and any other installations remain watertight. When rain falls and the water is guided by your roof towards your gutter guards and gutters, these valleys that remain between the roof, chimney and skylight, would normally allow water to flow through, damaging your walls and property. Flashing installations are in place to prevent that, keep your roof decking dry, and prevent water from flowing through to reach the more fragile areas of your home.
A few years ago almost all flashing was made from lead sheet. Although that’s still an option today, it isn’t the only one. Because of the cost of lead and because of renewed concerns regarding lead contamination, materials such as zinc, plastic and rubber are more commonly used. Lead flashing is normally utilized with a coat of waterproof paint for added protection.
