These 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 to and other wise dark place to work.
