We ship our foam roof panels across the locations throughout the country for all types of ceiling and roof designs that need an efficient, easy-to-install insulation option. If you’re dealing with a cathedral ceiling you may need a bit of extra assistance in specifying exactly how much you need. Our roof area calculator takes in your project details to work out exactly that. Simply input the building width at the gable end, length of building and the pitch of the roof. From that point the roof spaces and areas are calculated to estimate your insulation requirements. Find the online calculator here .
