Pre-engineered systems are changing building efficiencies for the better. A trussed roof, or a truss, is a pre-engineered A-frame structure that offers strong support and reduced labor costs. They can be installed as one piece. Therefore, they’re widely used in building construction. 

What if your client wants a skylight in the mix? At first glance, it may not seem possible but it’s actually not that difficult. Skylight installations in truss roofs should be just like any other skylight installation. First, consider the roof structure and the best way to distribute daylight. Second, get creative.

With a new build, it’s easy to factor skylights in, but with truss roof retrofits, the bottom line is: consider the best way to approach the install to maximize natural light in a bedroom or living space without having to get into deep engineering. There are several key things to keep in mind.

Don’t Cut the Truss Unless You Absolutely Must
It’s simply not a standard practice to cut a roof truss. Doing so can create an engineering nightmare because, by definition, truss roofs are pre-engineered and not made to be customized or modified. Once they are modified, the design and the load are compromised. Read More.
