The Vevor roof pipe flashing boot is designed to fit pipe outside diameters from 10" to 19" and create a tight, leak-resistant seal around roof penetrations. Its flexible silicone boot is built to handle temperatures from -101°F to 437°F while resisting corrosion, oxidation, rain, snow, and UV exposure. The 0.6 mm aluminum round base adapts to both sloped and flat roofs for a snug fit and easier installation. This flashing boot is suitable for metal, wood, and other roof materials, and works well for chimneys, vents, wood stoves, pipe openings, and tent pipes.
