Skylights allow natural light to enter an area through the ceiling. Homeowners install them to reduce electricity costs and illuminate without harsh lighting. The basic types of skylights are frame-in-place and curb-mounted. The first version is installed flush with the roof plane and secured with L-shaped brackets. Curb-mounted skylights rest on curbs above the roof plane. Skylight installation is actually easier than installing a window.

Framing a rough opening is the first step in installing a skylight. A skylight framing assembly features three parts and a framed curb is required for a curb-mounted skylight. Headers are used to frame the roof opening and the ceiling opening is framed in a similar manner. Framing connecting the ceiling and roof openings is called the light shaft. It may be flared or vertical and is insulated and finished.
Installing a skylight involves mounting the L-brackets on the side of the skylight, setting the skylight in the framed hole, and fastening it in place. A curb must be built for a curb-mounted skylight and this should be squared and caulked before the skylight is put into place and fastened. Shingles are then replaced, allowing space for flashing installation between their edges and the curb.
