    Answer This Question

    A:  Thank you for your question. This works for roof pitches 21/12 when adjusted for 1-1/2 in. and 2 in. pipes and up to 14/12 for 3 in. pipe.

    by|Jul 5, 2023

      A:  45 degrees is a 12/12 pitch. This should be capable of going to 14/12 which is approximately 49.5 degrees. Based on their specs it should work on your roof.

                    I needed a boot to cover a vent pipe because I was getting rain leaking into the house and this fit what I needed, glad they had it.
