How Much Do Roof Trusses Cost: Prices, Factors, and Estimates

Roof truss cost is a common question for homeowners and builders planning new construction or roof replacement. This article explains average costs, the factors that drive price variations, installation expenses, and practical tips to estimate and reduce total project costs. Key takeaway: truss material, design complexity, and labor are the primary cost drivers.

Truss Type	Typical Cost Per Truss	Notes
Standard Prefab Wood Truss	$100–$350	Most common for residential projects
Attic/Scissor Truss	$250–$600	Higher due to complexity and materials
Metal/Steel Truss	$400–$1,200+	Used in long spans or specialized builds
Custom/Architectural Truss	$500–$2,000+	Complex geometry, heavier engineering costs

Average Roof Truss Costs

Average roof truss costs range widely depending on size, design, and materials, but a reasonable benchmark for typical single-family homes is $2.50 to $7.00 per square foot of roof area for the trusses alone if priced by area. When priced per truss, most standard wood trusses fall in the $100 to $350 range, while specialty trusses cost significantly more.

For an average 2,000-square-foot house with a moderate roof pitch, the truss package often runs between $5,000 and $14,000 before installation. Larger or more complex roofs can exceed this range.

Cost Factors That Affect Roof Trusses

Material Type: Wood trusses are the most economical for residences, while steel trusses cost more but offer longer spans and higher durability.

Truss Design And Complexity: Simple roof lines with common truss types are less expensive. Attic-bearing, scissor, or custom architectural trusses increase fabrication and engineering costs.

Span And Size: Longer spans and larger trusses use more material and often require stronger webs and chords, increasing cost.

Roof Pitch And Load Requirements: Steeper pitches and higher snow/wind load requirements require more robust trusses and additional engineering, which raises price.

Location And Local Labor Costs: Regional labor rates and transport distances to the truss plant affect the final price. Remote areas typically pay more.

Engineering And Permits: Engineered trusses include design and stamp fees. Structural reviews and local permitting costs add to the total.

Types Of Roof Trusses And Price Ranges

Common Prefabricated Wood Trusses

Common truss types like king post, queen post, and common web trusses are mass-produced and priced lowest. Typical cost per truss: $100–$350.

Attic And Scissor Trusses

Attic-containing and scissor trusses provide usable attic space or vaulted ceilings but require more material and precise fabrication. Typical cost per truss: $250–$600.

Gambrel And Hip Trusses

Complex roof shapes such as gambrel and hip trusses involve additional connections and sometimes partial field framing. Typical cost per truss: $300–$800.

Steel Or Engineered Trusses

Steel trusses are common for long-span and commercial applications and carry higher material and fabrication costs. Typical cost per truss: $400–$1,200+, often higher for custom sections.

Custom Architectural Trusses

Custom patterns, exposed timber, or heavy timber trusses used for visual impact are the most expensive. They require special engineering and skilled installation. Typical cost per truss: $500–$2,000+.

Labor, Installation And Additional Costs

Installation labor typically ranges from $2 to $6 per square foot of roof area for lifting and setting trusses, depending on site complexity, crane needs, and crew size.

Cranes and Equipment: Crane rental for setting trusses can run $800–$2,500 per day depending on crane size and job site access. Smaller jobs may use telehandlers at lower cost.

Bracing, Blocking, And Decking: Temporary bracing, permanent bracing, blocking, and sheathing add material and labor costs. Budget an additional $1.00–$2.50 per square foot for these items.

Transport And Delivery: Truss plants charge delivery fees based on distance and load size. Delivery can be a few hundred dollars to over $1,000 for long hauls or special handling.

Inspections And Stamps: Engineering stamps, special inspections, and permit fees vary by jurisdiction and can add to a project, depending on complexity.

How To Estimate Truss Costs For A Project

Estimating roof truss costs accurately requires a few inputs: roof area, roof pitch, truss spacing, type of truss, and local labor rates. A common truss spacing is 24 inches (2 feet) on center.

Example Calculation: For a 2,000-square-foot roof with 24-inch spacing and simple prefabricated trusses: assume about 30 trusses (depends on design), each at $200 average = $6,000 for trusses. Add installation ($3,000), bracing and decking ($3,000), and delivery/permits ($1,000) for a total around $13,000.

To convert per-truss pricing to per-square-foot, divide total truss package cost by roof square footage; this helps compare quotes from different suppliers on equivalent bases.

Saving Money Without Sacrificing Quality

Order Standard Designs: Use common, standardized truss designs when possible to reduce fabrication and engineering fees.

Bundle Materials: Buying trusses, sheathing, and other roof materials from the same supplier or contractor can yield volume discounts.

Competitive Bidding: Obtain multiple quotes from truss manufacturers and roofing contractors. Price differences of 15–25% are common.

Optimize Roof Design: Simplify roof geometry—fewer valleys, hips, and dormers—reduces the number of specialty trusses and on-site framing adjustments.

Plan Logistics: Coordinate delivery timing and site access to avoid crane idle time and extra handling fees.

Warranty, Quality, And Longevity Considerations

Truss Manufacturer Warranty: Many factories offer limited warranties on fabrication and materials; review terms for coverage duration and exclusions.

Quality Of Materials: Higher-grade lumber or pressure-treated members resist rot and insect damage but cost more. Properly specified trusses last decades when installed correctly.

Inspection And Maintenance: Regular roof inspections and timely repairs of roofing materials help protect truss integrity over the building life cycle.

Key Questions To Ask Manufacturers And Contractors

• Are truss designs engineered and stamped for local load conditions?
• What is included in the quoted price (delivery, bracing, blocking, crane, permits)?
• What are lead times and potential delays?
• Is there a warranty on fabrication and materials?
• Who coordinates on-site layout and bracing responsibilities?

Common Mistakes To Avoid When Budgeting For Trusses

Ignoring Site Conditions: Restricted access, limited crane placement, or difficult terrain can dramatically increase installation costs if not identified early.

Failing To Include Bracing And Blocking: Underestimating these items leads to unexpected change orders during installation.

Overlooking Permits And Engineering Fees: These soft costs add up and should be included in the early budget.

Where To Get Reliable Quotes And Additional Resources

Contact local truss manufacturers for detailed quotes that include engineered drawings and delivery. General contractors and roofers can provide bundled pricing that often simplifies logistics. Industry associations and local building departments offer resources on load requirements and best practices.

Useful Next Steps: Gather roof plans, confirm roof pitch and loads, and request at least three detailed quotes including stamps, delivery, and installation scope to produce an accurate budget.
