The 4" Selkirk Adjustable Flashing is the best way to waterproof where the pipe comes through a shingle roof. The flashing tucks under the shingles on the top side of the roof and overhangs the shingles on the lower side of the roof.

The flashing is available in two adjustable roof pitches. Low pitch can accommodate any roof between 0/12 and 6/12 and the Steep pitch can accommodate any roof between 6/12-12/12.

Note: This flashing is only good for shingle roofs. If you have a metal roof, you would want to use the rubber boot flashing. Includes a stainless steel Storm Collar.
