Flashing is a relatively small roofing component, yet it’s a crucial part of every type of roofing system that can help prevent major roof damage. In this blog, the local roofing contractors at South Shore Roofing, Inc. share a quick guide on flashing.
Every roof has breaks in the roofing material such as seams and transitions between roofing planes, which are vulnerable to water infiltration. Flashing protects these areas from leaks. Some types of flashing help route rainwater to the gutter troughs. A typical commercial or residential roof may utilize one or more of the following types of flashing:
The perfect roof would be seamless as an egg, with no points for water to infiltrate. However, this is not possible because of breaks in the roofing plane, as well as the need for vent and chimney pipes. Without flashing, rainwater would easily infiltrate these areas. It should be noted that flashing may get dislodged, damaged or corroded and will need to be replaced. It is normal for any roof to undergo flashing replacement at least once in its lifetime.
