Hi All,
I just purchased 12 used Fafco panels and I have an installation question. The Fafco manual says
"2. Lay down the first panel. Be certain it is straight and square on the roof.
Simply lay substrate underneath each panel."
What is the substrate? I can seem to find a reference any where. We have a composite shingle roof.
thanks,
Steve
