This silicone roof flashing is designed to help seal roof tube and vent openings with a flexible stepped cone and a square metal base plate. The black rubber body forms a practical roof waterproofing around penetrations, while the rigid base supports a more stable fit on the roof surface. As a roof tube flashing, it is made to direct tube vent opening across the top opening and protect the area where leaks can develop. The stepped cone opening functions as a vent boot that can accommodate multiple tube diameters, making installation more adaptable when working with different vent sizes. The square base tube boot measures 250 mm by 250 mm, with an overall height of 100 mm, giving it a compact profile for roof applications. It fits tube diameters from 2-3/4 in to a maximum 7 in (70-178 mm), so it can be used in a range of common tube and vent setups without relying on a one-size-only opening. It is also shown as heat- and cold-resistant, with an indicated temperature range from -165.2°F to 446°F. That makes it suitable for roof areas visible to changing weather, where a dependable flashing helps support long-term sealing performance around tubes and vents.
