Roof Foam Peeling

Maybe on balance the dollar cost is the same but roofing is a messy business and that s a lot of foam to go into a landfill.

Roof foam peeling.

Direct attachment peel stick to the plywood then use 2 foam process to attach the concrete roof tiles. It s not coming from above the roof and it s not some new moisture source resulting from the spray foam. A metal roof may need to be replaced when it grows rusty and begins leaking. But if you have an spf roof and don t re coat it in a few decades it will probably have degraded to such a point that it will have to be torn off and completely redone.

Moisture generated indoors or that infiltrates into the home is responsible for the bulk of the moisture in an attic insulated with spray foam on the underside of the roof sheathing. Cleaning and inspecting the roof regularly can help prevent major damage from occurring. Install 30 roofing paper mechanically attached to the plywood then peel and stick then 2 foam process to attach the concrete roofing tile. On a hip roof there isn t much point in spend extra for ventilation channels above the rigid foam since soffit to ridge venting is impossible on a hip roof.

Lstiburek takes blame for bad language. My roofing contractors offers two methods which pass county code. You ll just have higher energy bills than a house with code minimum insulation. Either way use a wire brush to remove what foam is left if it s falling apart.
