Roof flashing: the metal that keeps water out of the joints
Flashing is the thin metal installed at roof transitions—walls, valleys, chimneys and penetrations—to divert water and prevent leaks. Here are the types we use and where each one goes.
Where each type protects your roof
Step Flashing
Overlapping metal pieces installed where a sloped roof meets a vertical wall, stepping up the wall to direct water back onto the roof surface.
Corner Flashing
Used at corners and transitions to keep water out of the joints where roof planes and walls meet.
Roof-to-Wall Flashing
Protects the connection between the roof and a wall, directing water away from the joint instead of into it.
Drip Edge Flashing
Installed along the eaves and rakes to guide water away from the decking and fascia and into the gutters.
Chimney Flashing
A layered system (base, step and counter flashing) that seals the transition between the chimney and the roof—one of the most leak-prone areas on any roof.
Pipe / Penetration Flashing
Boots and collars that seal around plumbing vents, pipes and other penetrations so water can’t sneak in around them.
Flashing is where most leaks start
The field of the roof rarely leaks—it’s the transitions, walls, chimneys and penetrations that fail first. Properly installed flashing diverts water away from every one of these vulnerable joints, which is why we never cut corners on it.
