This detail is suitable for flashing round pipes used to support equipment, electrical conduit, water and gas lines, sheet metal vent flues, plumbing soil pipe vents and other similar penetration.
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices.
Continuous cleats are recommended when flashing face dimension exceeds 3 inches and in areas deemed high-wind zone as categorized by local building code.
