Dektite Ezi Seal Flashing
The Dektite Ezi-Seal is one of the easiest to install roof flashings. The Ezi-Seal is the ideal flashing for polycarbonate roofs as it seals well to the roof and does not react with the polycarbonate. Around the flexible base is a non porous sponge gasket that seals by compression. You can install an Ezi-Seal flashing even when the roof is wet!
No silicone sealant is needed - the base is simply fixed into place with self tapping screws or rivets. The EPDM cone of this roof flashing seals around the flue and can withstand temperatures of -50 to 115 degrees. Ezi-Seal is covered by a 20 year warranty.
