Tip #215: Use factory built roof trusses instead of site-built rafter systems for your roof
You can save on your addition or remodel if a roof is required by using factory-built roof trusses. Site-built rafter systems are, as the name implies, built on site. The lumber cost will be more for these than for the factory-built truss. The labor cost to install complete trusses will be much less than to build a rafter system. If time is a factor in your addition or remodel schedule, using trusses will also save time – maybe as much as two or three days.
