DuraVent B-Vent Adjustable Flashing is used to waterproof seal around the pipe to waterproof the roof penetration. The flashing is available in 0/12 thru 6/12 pitch for low slope roofs and also 7/12 thru 12/12 for steeper roofs. The flashing is used for shingle roofs only. The flashing will tuck under the shingles on the top and will overhang the shingles on the lower side. Constructed out of galvalume steel to ensure the longevity of the flashing.

Note: A storm collar is required to seal around the pipe when it passes through the top of the flashing.
