The FlashCap® is a roof flashing specifically designed for plumbing vent pipes. FlashCap® is a 2 piece system, the flashing and the cap. The cap is a counter flashing that fits inside the vent pipe and over the flashing. FlashCo® manufactures standard FlashCap® boots and flashings using reinforced TPO and PVC single ply membrane and various metals such as Lead and Copper. The single-ply and lead caps are seamless completely eliminating the need for additional time, such as adding a hose clamp or bending the material into the vent. The water intrusion concern is eliminated with FlashCap®.
