These shed roof skylights will add the “cool factor” to your outdoor shed, playhouse, or barn. They are made of unbreakable plastic and are bronze-tinted. The easiest way to secure the skylight is to put a bead of roofing cement under the flange and then install with exterior screws around the perimeter. Then put a small amount of roofing cement on top of each screw and shingle the roof. These are great for adding natural sunlight too and otherwise dark places to work.
