I am building a new powder room (toilet & lav) and I need to install a new 1-1/2" vent through the roof. The piping will be PVC. The roof is essentially flat (1/12 pitch) and is a roll roof (composition type sheets approximately 4' wide), with a silver reflective coating applied to reflect solar energy. I am thinking of using a roof flashing which has a galvanized plate, with a neoprene boot that is flexible enough to accommodate the low pitch. Similar to this:
I would using roofing cement, slide on the flashing, then apply more roofing cement, roofing felt around the perimeter, and more roofing cement on top. Does this sound like a good solution?
