ACRYLIC ROOFING:  SKYLIGHTS

Skylights have four outside corners, so the flashing technique is very similar to that for outside corners. If the skylight and mounting curb are two separate pieces, removing the skylight while applying the acrylic roof will keep the glazing clean and make it easier to properly waterproof the curb. Follow these procedures just before beginning to waterproof the main roof surface.
