Trust me, you don’t want to skimp on this vital part of your roofing system!
Understanding Roof Flashing: Your Home’s Silent Guardian
Roof flashing is like that quiet kid in class who always has the right answer but never brags about it. It’s a thin, usually metallic material strategically installed on your roof to redirect water away from critical areas. Think of it as your roof’s personal bodyguard, always on duty to protect against water infiltration.
The Anatomy of Roof Flashing
Roof flashing isn’t just a single piece of metal slapped onto your roof. It’s a carefully designed system comprising various components:
- Step Flashing: This type is installed in “steps” along roof-to-wall intersections.
