Foaming a low-pitched roof
I have a 4/12 roof that is being converted to an unvented attic. The foam subcontractor assured me that he could get foam, being sprayed on the underside of the roof, to the plate line. He finished the job assuring me that they had been successful.
I drilled holes and used a scope to see the void that extends out to 6 -10″ from the exterior wall plates. How much of an issue is this?
