How to detect a roof leak after having the underside of the roof deck sprayed with closed-cell foam?
I live in Buffalo, NY, and am renovating a Cape Cod style home. The interior is completely gutted and had a roof tear off and GAF system installed with no ventilation, with the plans for having the deck sprayed with closed cell. I had a question that no one up here can answer…
As the roof fails or if there is some sort of damage, how will I know if the underside is 100% sealed? My fear is the water will rot the rood substructure and hold mold. Is there any way to create a path for any potential leaks to follow??
