How to Choose the Right Roof Truss for Your Project
Choosing the right roof truss is key to a strong, lasting roof that fits your project's needs and budget. Roof trusses provide the frame that supports your roof, handles weather loads, and shapes your home's look. With options for homes, garages, or additions, the process doesn't have to be complicated. This guide breaks down simple steps to pick the best one, helping builders and homeowners avoid common pitfalls.
Understand Your Project Basics
Start by looking at your building's size and purpose. Measure the span—the distance the truss must cover without middle supports. Common spans for homes run 20 to 40 feet, while garages might need shorter ones. Next, think about roof pitch, or slope. A steep pitch sheds snow and rain better in wet areas, while a low pitch suits warmer climates or modern styles.
Your local weather matters too. In snowy regions, choose trusses that handle heavy loads. For windy spots, focus on ones with strong bracing. Sketch your roof plan early to match these needs. This step ensures your choice supports the full structure safely.
Explore Common Roof Truss Types
Different truss designs serve unique goals. The king post truss works well for simple, open spans up to 30 feet, creating a classic peaked roof with minimal parts. For wider areas, try the fink truss, which uses zigzag supports for strength without blocking attic space.
Scissor trusses vault the ceiling for a spacious feel, ideal for great rooms. Attic trusses add bonus room space above, perfect for storage or offices. Mono-pitch trusses suit additions or sheds with a single slope. Pick based on your ceiling style—flat, sloped, or open—and span length. Experts at Structural Wood Corp can match these to your plans.

Factor in Load and Material Choices
Trusses must bear dead loads like shingles and live loads from snow, wind, or people on the roof. Check local building codes for exact requirements—most areas list minimums online. Wood trusses suit most homes for their speed and cost, while steel handles longer spans or fire-prone zones.
Wood offers natural insulation and easy installs, but pick treated lumber for damp climates. Steel resists pests but costs more upfront. Get engineer-stamped drawings to confirm loads match your site. This prevents sags or failures down the road.
Budget and Long-Term Savings
Roof trusses save time and money over stick-built roofs. Factory-made units cut labor by half and ensure precision. Prices range $100 to $500 per truss, depending on size and type. Factor in delivery, install, and bracing hardware.
Buying custom trusses upfront avoids rework costs. Compare quotes with spans, pitches, and extras listed. Renting isn't common, but buying from reliable makers like those at Structural Wood Corp ensures quality without overpaying. Long-term, durable trusses boost home value and lower repair bills.
Installation and Pro Tips
Work with a team that follows a design checklist: confirm spans, pitches, bracing spots, and bearing points. Permanent braces keep trusses stable during storms. Hire certified installers to meet codes and pass inspections fast.
Test fit a sample truss on-site. Space them 24 inches apart for standard roofs. Add extras like hurricane ties in risky areas. Plan for ceiling finishes early to avoid cracks at joints.
