GenFlex TPO Reinforced Pipe Boots are factory fabricated boots made from high performance GenFlex roofing membrane. The boot is specifically designed to be used in roofing applications for flashing round penetrations and will fit various sizes. The tab design allows the boot to be used to flash pipe penetrations with limited or no access from above. The design eliminates the need to use non-supported flashing thus reducing labor and increasing the performance of the detail and system.
