Typically for pipe vent penetrations and solar stanchions on single-ply roofing systems.
Round Pipe Flashings are not universal, but they install faster and look better. Round pipe flashings are closed/Split and made to fit snugly over the penetration. They are made from reinforced membrane which most professional roofing applicators prefer over detail membrane or premolded membrane because reinforced is stronger. The most common application for these pipe seals or flashings is plumbing vent pipes.
