The image on the left shows the concrete deck after the old roofing has been removed. The black coloring is a primer applied by Whiting Construction to aid in the adhesion of SPF to the deck. The pre-existing edge flashing has been removed and replaced with a 7” vertical rise gravel stop flashing. All wooden A/C sleepers and curbs have also been removed and replaced with galvanized metal units. The image on the right shows the same roof deck after SPF has been applied.
