Frequently Asked Questions
How much do roof trusses cost?
Roof trusses cost $35–$400 per truss depending on type and span. Simple gable trusses for a 24-foot span cost $35–$100 each. Attic trusses with usable storage space cost $150–$400 each. Scissor trusses (vaulted ceiling) cost $100–$300 each. Delivery typically adds $200–$500 and crane rental for setting adds $300–$600.
Trusses vs. rafters: which is better?
Trusses are factory-engineered, faster to install (1–2 days vs. 5–7 for rafters), 30–50% less expensive, and structurally superior for spans over 20 feet. Rafters allow more attic space flexibility and are better for complex custom roof designs. For standard new construction, trusses are the economical and practical choice. For renovations or unique roof designs, stick framing with rafters may be necessary.
How far apart should roof trusses be spaced?
Residential roof trusses are most commonly spaced 24 inches on center (OC). Some designs use 16-inch OC spacing for heavier loads or longer spans. Truss spacing is determined by the engineer based on roof load (snow, wind), span, and sheathing type. Do not change truss spacing from the engineered design without consulting a structural engineer.
Do roof trusses need a crane?
For most residential roof truss installations, a crane or boom truck is used to lift trusses into place. This is especially true for homes over one story or with long truss spans. Crane rental typically costs $300–$600 for a half-day. Some small jobs with short, lightweight trusses can be set manually with a crew, but crane use is standard and usually worth the cost for speed and safety.
