1. Cut to pipe diameter marked on flashing (this is approximately 20% smaller than the diameter of the pipe).
2. Slide the flashing down the pipe, using water to lubricate if necessary.
3. Form & bend the aluminum base of the flashing to fit the surface of the roof.
4. Seal the flashing by applying urethane/silicone sealant between the flashing & the roof.  Use a large slot screwdriver to press the base down tightly.
5. Fasten the flashing with weather-resistant fasteners to complete the seal.
