Flashing is placed in the joints and penetrations of your roof. Their main function is to prevent water from getting underneath the shingles and into your home. While it’s an important part of the roof, it often doesn’t get the attention it needs.
What Is Roof Flashing?
Roof flashing is a strip of metal that’s made to fit your roof. You can find it in sports that require added protection against water intrusions like chimneys and other penetrations. It helps the roof and walls expand and contract with temperature shifts without cracking. Moreover, it acts as a protection for the most vulnerable parts of your roof.
Residential roof flashing is usually made of aluminum, but it is also available in steel, lead, rubber and liquid forms. Keep in mind that flashing isn’t always exposed or obvious. This is one reason regular professional inspections are key in avoiding roofing repairs.
Why Is It Important?
Joints and penetrations are the most leak-prone areas of your roof. Joints are where two slopes intersect, and penetrations are anything that result in holes in your roof. Vents, chimneys and skylights are common types of penetrations.
Areas where there are joints and penetrations are opportunities for water to penetrate through your roof and into your interior. Flashing redirects water away from these areas and down into the gutters. If the flashing is damaged or missing, leaks will eventually develop in your roof. On the other hand, regular roof and flashing maintenance can help prevent leaks from occurring.
