The price of trusses for a house is usually $10,000-$30,000 for a typical roof, including delivery and installation, while a materials-only package may cost $5,000-$18,000. Total price depends mainly on roof area, span, pitch, truss design, local labor rates, and whether a crane or special delivery is needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Truss materials | $5,000 | $10,000 | $18,000 | Typical 1,800-2,400-square-foot house |
| Materials per roof area | $3 | $5 | $8 per sq ft | Varies with span, shape, and lumber grade |
| Delivery | $300 | $800 | $1,800 | Distance and oversized-load needs affect charges |
| Installation and setting | $3,000 | $7,000 | $12,000 | Includes crew labor and ordinary lifting |
| Installed roof truss package | $10,000 | $18,000 | $30,000 | Excludes roofing, sheathing, and major structural changes |
What a standard house roof truss package costs
For a straightforward, gable-roof house with roughly 1,800-2,400 square feet of roof area, truss materials commonly run $5,000-$18,000. A middle-of-the-range package is often near $10,000, before delivery, crane rental, and installation. The roof area used for pricing is not always the home’s interior floor area; overhangs and roof pitch increase the surface area.
Individual prefabricated trusses may cost about $60-$400 each for common residential designs. A basic truss for a shorter span can fall near the lower end; long-span, attic, girder, or heavily loaded designs can exceed $500 apiece. Contractors often quote a complete engineered package rather than a simple count multiplied by a unit rate.
For budgeting, allow about $5-$8 per square foot of roof area for typical truss materials and roughly $8-$14 per square foot for a supplied-and-set package. These are planning ranges, not a fixed national rate. Assumptions: standard wood trusses, ordinary access, no unusual snow or wind engineering, and a conventional residential roof.
As a simple quantity check, trusses spaced 24 inches on center require approximately one truss for every 2 feet of building length, plus gable-end framing as specified. A 40-foot-long house might need about 21 trusses, though the final layout depends on end conditions, openings, roof geometry, and the designer’s plans.
How lumber, delivery, and setting appear on a quote
Quotes may combine engineering and fabrication into one line, while delivery and setting are billed separately. Comparing bids is easier when each company identifies whether the price includes bracing, hardware, crane service, unloading, and final placement. The table shows common allowances for a mid-sized house rather than guaranteed line-item charges.
| Quote component | Typical price | What changes the charge | Common billing basis |
|---|---|---|---|
| Engineered trusses and lumber | $3-$8 per roof sq ft | Span, pitch, lumber grade, load design | Package or per truss |
| Engineering and shop drawings | $300-$1,500 | Design complexity and revisions | Per project |
| Delivery and unloading | $300-$1,800 | Travel distance, access, oversized loads | Per delivery |
| Setting labor | $3,000-$9,000 | Truss count, crew size, roof height | Project or hourly |
| Crane or telehandler | $500-$2,500 | Lift duration and equipment reach | Day or project |
Confirm whether the quote covers temporary bracing and permanent restraint details, since these can be essential to a safe, code-compliant installation. Some packages include standard connector hardware; others leave straps, clips, and fasteners to the framing contractor.
Labor can be estimated with the formula . A small crew may spend 8-16 hours setting a simple roof, while a complicated or difficult-access job can take 20-40 hours or more. At roughly $50-$90 per worker-hour, labor totals depend on crew size, equipment, and whether framing work is included.
Why 30-foot spans and steep pitches raise truss prices
Span is one of the strongest pricing drivers. A basic 20-foot span generally needs less lumber and engineering than a 30- or 40-foot clear span. As spans approach or exceed 30 feet, designs may require larger members, additional webbing, or a girder truss supporting intersecting roof sections. Long spans can add hundreds of dollars per truss and several thousand dollars to a full package.
Roof pitch changes both the truss geometry and the amount of material. A 4:12 pitch is typically simpler than a 10:12 roof, which has longer chords and may need more complicated handling. A steep pitch combined with a 30-foot-plus span can push pricing toward the high end even when the roof footprint is modest.
Trusses designed for attic storage, vaulted ceilings, or heavy snow loads cost more than standard trusses with an ordinary ceiling. An attic truss may add roughly 20%-50% to the price of a comparable standard design, depending on the usable room width and required floor loading. Snow and wind design loads vary by location and must be established from the project plans and local requirements.
Roof shape also matters. A simple gable roof usually costs less than a hip roof, multiple intersecting gables, or a design with dormers and valleys. Girder trusses, which carry loads from other trusses, are particularly expensive; a large or custom girder may cost $500-$2,000 or more. Changes made after engineering can trigger redesign charges and production delays.
When delivery distance or crane access changes the bill
Trusses are large, so delivery is not equivalent to a routine lumber drop. A local delivery may cost $300-$800, while a longer route, restricted unloading area, or oversized-load permit can bring the charge to $1,000-$1,800 or higher. Confirm whether the supplier can reach the site and place the load where the framing crew can use it.
Crane costs vary with equipment size, travel, and rental duration. A straightforward lift may add $500-$1,200; a larger crane, longer setup, or difficult reach may cost $1,500-$2,500 or more. A telehandler can be less expensive when the site and truss dimensions allow it, but it may not safely handle every roof design.
Site access can turn a low material quote into a costly installation if the truck or lifting equipment cannot get close to the building. Narrow roads, overhead utility lines, soft ground, steep driveways, and limited staging space can require extra labor or a different delivery plan. Before ordering, the builder should verify access with the supplier and equipment operator.
Additional charges may apply for extra trips, waiting time, manual unloading, or moving trusses after delivery. If a truck arrives before the foundation or framing is ready, rescheduling can cost several hundred dollars or more. The quote should state how long unloading is included and who pays for delays.
How regional labor rates shift the installed price
Installed pricing often runs 10%-20% above national planning averages in high-cost metro areas, including parts of the Northeast, California, and the Pacific Northwest. Areas with lower labor costs and nearby truss plants may come in 5%-15% below the middle of the range. These differences are broad estimates; local competition, fuel, and construction demand can outweigh regional patterns.
Climate and code requirements also influence the design rather than just the labor bill. In locations with substantial snow loads, high winds, or seismic requirements, engineering may call for stronger or more closely spaced components. A coastal project may need corrosion-resistant connectors, while mountain regions may require trusses designed for heavier roof snow.
Compare at least two local bids using the same plans and load specifications. A low quote may reflect a different truss spacing, omitted hardware, no crane, or a materials-only scope. Ask each supplier to confirm roof area, design loads, delivery distance, taxes, engineering, and whether installation is included.
Some jurisdictions require plan review, inspections, or documentation for structural components. Truss engineering is commonly provided with the package, but permit fees and inspection charges may be separate. Local fees can range from a modest administrative charge to several hundred dollars, depending on the permit scope and municipality.
Three house sizes and roof designs compared
These examples show how size and complexity change a quote. They assume wood trusses, ordinary access, and typical U.S. labor; they exclude shingles, underlayment, roof sheathing, gutters, and interior finishes. A contractor’s complete roof-framing proposal may include some of those items, so the scope needs to be checked.
| Example | Approximate roof area | Trusses and delivery | Setting labor and equipment | Estimated total |
|---|---|---|---|---|
| Small 1,400-sq-ft gable home | 1,600-1,800 sq ft | $4,500-$7,000 | $2,500-$4,000 | $7,000-$11,000 |
| 2,000-sq-ft home, standard pitch | 2,200-2,600 sq ft | $7,000-$12,000 | $4,000-$7,000 | $11,000-$19,000 |
| 2,600-sq-ft home, hips and valleys | 2,900-3,300 sq ft | $12,000-$20,000 | $6,000-$10,000 | $18,000-$30,000 |
The 2,000-square-foot example is a useful baseline, but a complex roof can cost substantially more than a larger, simple gable. For the standard-pitch example, a package near $9,000 for trusses and delivery plus about $5,500 for setting and equipment produces an estimated total around $14,500.
In these examples, the square footage is the approximate sloped roof surface, not necessarily the house’s advertised living area. A steep roof or wide overhang increases roof surface area. The count and type of trusses must come from the structural plans rather than a rough square-foot calculation.
Prefabricated trusses versus site-built rafters
Factory-built trusses often reduce on-site framing time and can be cost-effective for standard roof shapes. For a typical house, installed trusses may fall around $8-$14 per roof square foot for the truss package and setting work. Site-built rafters may cost roughly $10-$20 per square foot for comparable structural framing, but the result depends heavily on local carpenter rates, lumber prices, and roof complexity.
Rafters can suit custom ceilings, additions with unusual geometry, or projects where a crane cannot access the site. They may also allow more flexibility in the roof cavity. However, they require more field cutting and skilled labor, and structural sizing still needs to satisfy the design and code requirements. Comparing only lumber prices misses the cost of labor and engineering.
Choose between trusses and rafters by comparing the full framing scope, not the price of lumber alone. Include design, connectors, bracing, delivery, lifting equipment, labor, and any ceiling or storage requirements. A truss package is not automatically cheaper when the roof is highly customized or delivery access is difficult.
Which scope choices can lower a truss estimate
Keeping the roof shape simple is one of the most effective ways to control the budget. Several gables, dormers, valleys, and large overhangs require more specialized components and more framing time. If design changes remain possible, ask the architect or builder to price a simple roof geometry before final plans are approved.
Standard spacing and common pitches may reduce fabrication complexity, but spacing should never be changed just to save money without approval from the designer. Likewise, reducing lumber grade or design capacity is not an appropriate shortcut where it conflicts with engineering, local code, or expected loads. Compare specifications, not just the total.
Get the roof plans and loading requirements finalized before the supplier releases trusses to production. Late changes can mean redesign fees, restocking charges, replacement pieces, and schedule delays. Verify ceiling layout, attic use, mechanical openings, and any future solar or equipment loads before ordering.
Other practical savings can come from coordinating delivery with the framing crew, preparing a firm unloading area, and bundling truss delivery with other scheduled materials when the supplier offers a lower combined charge. Ask whether crane time can be shortened by staging the trusses in installation order. Avoid paying for premium finishes or storage capacity that the plans do not require.
For each quote, request a written breakdown for materials, engineering, delivery, equipment, labor, hardware, taxes, and disposal if applicable. Check whether the price includes temporary bracing and whether the contractor will correct damaged components. A clearly scoped estimate helps reveal whether a bid is genuinely lower or simply omits necessary work.
