Roof Trusses: Why They’re More Popular Than Ever

Fewer homes
today use rafters to support the roof — that’s because more new homes are built
with manufactured roof trusses.

These triangular
wood structures are built in a factory and delivered to the construction site for
installation after a home’s walls are built.

Here’s why more
home builders are switching from rafters to trusses.

1. They’re Engineered for Performance

The truss is the structural framework that supports the roof and ceiling joists. Trusses are carefully constructed, as one piece, in a factory to meet an engineer’s specifications.

The engineer makes sure that the truss can support your home’s roof design and that it meets any applicable building codes — which means the structural framework will be tailor-made, just for your home, and shouldn’t hurt your home’s resale value.

2. Trusses Require Few Load-Bearing Walls

trusses are designed to distribute the roof’s weight to the home’s outside
walls, so fewer interior load-bearing walls are needed.

Building a
home with rafters requires more load-bearing walls because builders — always working
at the construction site — physically can’t add rafters without them.
