Installing Skylights Between Trusses

Last Updated on: May 8, 2026
Never cut roof trusses — they are pre-engineered structural supports and cutting them compromises your entire roof and home integrity. Standard trusses are placed on 24-inch centers, creating a 22.5-inch rough opening that standard skylights are designed to fit. Detailed measurements are essential. Work with certified skylight installation experts familiar with proper flashing, adhesives, and sealants for a watertight result.

Installing a skylight in a newly built home is the best option for incorporating a skylight into your roof, though retrofitting your existing roof to accommodate skylights is also very doable. Where things can get tricky is installing a skylight between trusses, which are strong, pre-engineered supports for your roof. Here is our advice on how to approach installing skylights between trusses.

Installing Skylights Between Trusses

Installing Skylights Between Trusses

Understand that your roof is already engineered and designed to work structurally with your roofing system, the design of your home, and the environment your roof and home reside in. Your roof can withstand winds, specific weight loads, and weather, so installing anything on your roof system must be done strategically to take care to avoid any damage.

If your home has trusses, it’s important to work with an experienced and certified skylight installation expert. They will be familiar with ways to install your skylight into a pre-existing roof. They will be able to properly evaluate the layout of your roofing system, and the truss and rafter design.

It is recommended to never cut trusses in your roof and attic. If you start to cut them, the integrity of your roof and home can become damaged. It’s best to position your skylights between the sections of your roofing trusses.

If you and your skylight specialist want to move forward with a skylight system that fits in between your truss sections, detailed measurements need to be taken and applied to the design and choice of your skylight as well as the installation of your new skylight.

Do Roofers Install Skylights?

Roofers tend to stick within the roofing specialty and make sure homeowners receive the best roofing system and roof installation available. Your favorite roofer or builder might know a great skylight group that specializes in providing the best skylight install for its customers as well.

Roofers can be on sight to discuss the roofing layout and compare procedures to move forward with your skylight installation. A skylight installation team will be familiar with the proper flashing, adhesives, and sealants to deliver the perfect product and establishment of your skylights.
