Standard sizes of skylights run from 24”x 24” and 36”x24”. These are the typical sizes most manufacturers produce since they are a good size for skylights. Size can mean everything when choosing a skylight for your room. The size of the skylight affects the amount of light entering the room; therefore, the larger skylight, the better.

As a rule of thumb, the skylight size should never be more than 5% of the floor area in rooms with many windows and no more than 15% of the room's total floor area for spaces with few windows.

A deck mounting skylight attaches directly to the roof. This type of skylight has a lower profile and higher energy efficiency than curb mounts. You also have the benefit of not having to construct and provide flashing for a separate curb. Some deck mounted skylights, like SIG’s, are made with built-in flashing. Self flashing skylights have a metal, plastic, or rubber “flange” (the part that seals directly to the roof), and these flanges range from about 2” to 5” wide.

Can a skylight leak?

A skylight is part of your roof, and if installed properly, can be a beautiful, functional, trouble-free feature. Installed improperly, however, they can cause leaks. With either deck mounted or curb mounted skylights, you need to take steps to ensure the installation is watertight with good quality self-sealing underlayment and proper flashing technique. Unless you are a serious DIYer, it is safest to have a well qualified contractor install your skylights. A skylight specialist may be the most expensive option. Sometimes they are affiliated with and install skylights from just one major skylight supplier. Another fine option is a builder or remodeling contractor. Roofers are also commonly installers of skylights, as a good time to replace a skylight is when the roof is being replaced. This is discussed in another blog. For skylight replacements or installations on an existing roof, it is best to use an experienced roofer. Either way, we recommend you review the manufacturer’s installation instructions with the contractor to be sure they agree to follow the skylight manufacturer’s guidelines. Regardless of who you choose, make sure they are experienced in installing skylights, and particularly the type of skylights you plan to use. Also, insist on an installation warranty against leaks in addition to the skylight warranty provided by the manufacturer. References are a good idea, and – as always – make sure the contractor is bonded and insured. SIG Skylights is happy to give you the names of skylight installation contractors who have installed our skylights in your area.

A tubular skylight functions by capturing the natural direct rays of the sun inside of the tube from the roof of a structure, and bouncing them off of the walls of the tube and down into the room below.
