You'll spend anywhere from $1.50 to $4.50 per square foot of building area for materials alone, or between $35 and $150 per truss, though extremely long and complex types can reach $400 each. Labor runs anywhere from $20 to $75 per hour. Ranges in both materials and labor are due to location, size and roof complexity.

Why are trusses cheaper than rafters?
Trusses are lightweight engineered units consisting of top and bottom "chords" supported by a webbing of lumber in a triangle shape. Because they're pre-made to your building specs offsite, often via automation like computer-driven saws, they are much faster and cheaper to install than rafters.
What kind of wood is used for roof trusses?
Kiln-dried Douglas fir wood presents the number one choice for building a rafter-styled roof in a wood frame house.
What size of wood is used for roof trusses?
Trusses for common structures like houses, carports, and gazebos are most often constructed using 2 in (5.1 cm) x 4 in (10 cm) wooden boards.
Are roof trusses 2x4 or 2x6?
Trusses only use 2×4 lumber and are constructed using a “web” of 2x4s for strength. Rafters simply rely on a center ridge beam and the outside walls for support. While there are benefits to both, only rafters vary in the size of lumber that is used.

Can you use 2x4 for roof joist?
A 2×4 can span a maximum of 6' 7” when spaced 16” apart and used as a floor or deck joist. When used as a ceiling joist or a roof rafter, a 2×4 can span up to 7' 3” spaced at 16”, and 6' 4” when spaced 24” apart. Due to the small spans of 2x4s, they often are not used in horizontal load-bearing capacities.
