ABSTRACT:
A sprayed closed cell foam roof is prepared by applying the foam directly to the entire roof deck and layering the foam with sufficient gravel to prevent ultraviolet light deterioration of the foam. The roof is devoid of the waterproof layer conventional in foam roofs that leads to leaks and other failures common to such roofs.
