How Proper Flashing Prevents Roof Leaks in Plymouth Michigan

How Flashing Protects The Weak Spots On A Roof

Most roof leaks do not start in the middle of a shingle field, they start where the roof has to meet something else. Around here, flashing is not a detail for the installer to "finish later", it is part of the waterproofing system that keeps the house dry.

Flashing is the thin metal or membrane material used around chimneys, walls, skylights, valleys, step transitions, and penetrations like vents and pipes.
