Pipe Flashing

1

Cut to pipe diameter marked on Flashers (this is approximately 20% smaller than the diameter of the pipe).

2

Slide the Flashers down the pipe, using water to lubricate if necessary.

3

Form and bend the aluminum base of the Flashers to fit the surface of the roof.

4

Seal the Flashers by applying urethane / silicone sealant between the Flashers and the roof. Use a large slot screwdriver to press the base down tightly.

5

Fasten the Flashers with weather-resistant fasteners to complete the seal.
