Proper install of Plumbing Boots

plumbing boots or “oaties” are rubber gaskets that surround the plumbing vent stack to prevent water where the stack penetrates the roof deck

When evaluating the quality of install of Plumbing boots please consider the following:
– shingles overlapping the flanges of the vent are solid pieces
– a minimum 1″ space between the vents base and the shingles surrounding it
– tar over all nail heads
