We make roof dormers and other outside corners leakproof
Outside corners on dormers need special flashing details to prevent water leaks. Here are two foolproof methods for making sure that corners shed water and stay dry for the life of the roof.
The two ways are good to handle corner flashing. The first, bending two pieces and caulking the joint, is the most common because you can do it on the spot with the flashing at hand.
- Wrapped corner method
Soldered corner method
The second, forming and soldering a custom piece to fit the corner, is the best because it doesn’t leave any potential leak spots (at the caulked gaps).
