INSTALLATION EDUCATION: Plumbing Vent's Lead Boot
Air over water is how waste water is carried away from our homes. Air is introduced into the plumbing system through vent pipes that protrude through the roof. These pipes serve double duty, allowing sewer gases to escape into the atmosphere rather than back into our living spaces. Vents protrude through holes in the roof deck and require ‘flashing’ for waterproof assurance. This flashing comes in a pliable product called a ‘lead boot’, which conforms to various roof characteristics. (Rubber boots are not used in tropical climates where extreme sunlight deteriorates the rubber prematurely.) Our five layer protection ensures a Done Right–Rain Tight installation every time, guaranteed.
Our lead boot installation begins with a layer of Atlas WeatherMaster Peel & Stick Reinforced Underlayment with the vent opening sealed liberally with roofing cement (Image-1).
Shingles are then installed up to the vent pipe prior to boot placement (Image-2).
Roofing cement is applied over the layer of shingles before fastening the lead boot with nails (Image-3). Another layer of roofing cement is liberally applied, sealing the edges and the base of the lead boot base to the final layer of shingles (Image-4).
That’s it! Lead boots Done Right–Rain Tight, keeping water in the pipes and looking sharp to boot
