The cost of wood trusses is typically $60-$500 per truss, or about $5-$14 per square foot of roof area for trusses alone. A complete installed package for a typical house roof often runs $8,000-$20,000, with span, roof shape, lumber grade, delivery distance, and crane or crew needs driving the quote.
Prices below assume standard residential construction; unusually long spans, complex roofs, and high-cost metro areas can exceed the ranges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Common individual truss | $60 | $150 | $500 | Price varies by span, load, and design |
| Trusses per roof area | $5 per sq ft | $8 per sq ft | $14 per sq ft | Material package, not full roofing |
| Installed residential package | $8,000 | $13,000 | $20,000 | Typical house roof with delivery and setting |
| Small garage trusses | $600 | $1,500 | $3,500 | About 10-20 standard trusses |
What a typical wood truss roof costs by size
A common gable roof on a 1,500-square-foot home may require roughly 25-35 trusses, depending on building length and spacing. A basic package can cost $4,000-$9,000 for trusses, while delivery, setting, bracing, and related labor can bring the installed truss portion to about $8,000-$16,000. This is not the price of a finished roof, which also includes decking, underlayment, flashing, and shingles or another covering.
For a 2,000-square-foot home, a standard engineered-wood package often falls around $6,000-$12,000 before installation. A more complex hip roof or one with vaulted ceilings, multiple valleys, or large openings can push the truss package to $10,000-$18,000 or more. Per-square-foot figures generally refer to the building or roof area identified in the quote, so buyers should confirm the measurement basis.
For a straightforward house roof, budgeting $8-$14 per square foot for trusses, delivery, and setting is a useful initial estimate. Assumptions: standard residential lumber, ordinary access, typical regional labor, and no major engineering revisions.
How lumber, fabrication, and setting appear in quotes
Truss estimates can combine fabrication and installation or list each separately. Comparing line items helps reveal whether a low quote excludes delivery, engineering documents, temporary bracing, crane service, or installation. The table shows common budget ranges for a standard residential job; actual allocations vary because suppliers bundle services differently.
| Quote component | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Truss lumber and plates | $5-$14 per sq ft | Roof area | Fabricated trusses and connector plates |
| Engineering and shop drawings | $150-$800 | Per project | Design calculations and layout documents |
| Delivery | $250-$1,200 | Per load or job | Truck transport, distance, and access conditions |
| Installation labor | $3-$8 per sq ft | Roof area | Unloading, positioning, fastening, and bracing |
| Crane or lift equipment | $500-$2,000 | Per day or job | Equipment where manual handling is impractical |
| Disposal and corrections | $100-$1,000 | As needed | Packaging, damaged members, or small field fixes |
Installed truss labor varies with crew size, roof height, and truss weight. A crew may set a simple roof in one to three days, while complicated layouts may take longer. For a crew billed by time, gives a basic labor estimate; residential framing rates often work out to about $50-$100 per worker-hour before equipment and contractor overhead.
Ask whether the quote includes delivery, crane time, engineering, bracing, and installation before comparing totals. Assumptions: normal road access and no separate permit, roof-decking, or roofing-material charge.
Which span, spacing, and roof shape raise the price
Span is one of the strongest price drivers. A standard truss spanning 20-30 feet may cost about $60-$200 each, while a 40-50-foot span can run $250-$700 or more because it needs deeper members, stronger connections, and sometimes specialized transport. Prices depend on design loads and lumber availability, not span alone.
Spacing also affects quantities. Trusses commonly sit 24 inches on center, but 16-inch spacing uses about 50% more trusses over the same building length. Closer spacing can be required by the design or roof loads; it should not be changed just to cut the quote without approval from the project designer.
Roof geometry matters as much as square footage. Basic gable trusses are generally less expensive than hip, scissor, attic, or mono trusses. Scissor trusses for a vaulted ceiling may add roughly 20%-50% over a comparable standard truss, while attic trusses with storage space can add 30%-70%. Multiple valleys, dormers, and openings require more distinct pieces and coordination.
Loads and local requirements can add cost. A design for a high snow load, strong wind exposure, or heavy ceiling finish may need larger members or added bracing. For example, a project designed for a 40-psf snow load may price differently from one designed for 20 psf, but the exact difference depends on span, pitch, building code, and engineering.
Long spans over 40 feet, spacing tighter than 24 inches, and specialty truss shapes deserve separate pricing in the estimate. Assumptions: engineered trusses designed for the site’s code loads and specified roof plan.
When engineered wood beats site-built rafters
Wood trusses are factory-built assemblies, while site-built rafters are cut and installed at the property. Trusses often reduce framing time and can be economical for broad, repeated roof layouts. A standard truss package may cost $5-$14 per square foot before setting; site-built rafters can cost roughly $8-$18 per square foot for framing materials and labor, with higher totals for complex roofs or premium lumber.
Those ranges are not direct substitutes in every design. Rafters may work better when the plan needs an open cathedral ceiling, unusual framing geometry, or changes that are difficult to accommodate with a truss web. Trusses require careful layout and cannot be cut or altered casually after fabrication. A structural professional must approve any change because cutting a web or chord can compromise the assembly.
Engineered trusses can also reduce on-site cutting waste, but savings depend on transport, crane access, and the design. For a small addition or irregular roof, compare a truss quote with a complete rafter-framing quote that includes labor, blocking, and required structural connections.
Compare complete framing scopes, not just the price of trusses against the price of loose lumber. Assumptions: standard-grade framing materials and comparable code-compliant roof loads.
How regional labor and delivery change the total
Prices vary with lumber supply, contractor availability, fuel, and local building practices. In many rural markets, a simple project may price 5%-15% below the national middle range, although longer delivery routes can erase the difference. Major metro areas and high-cost coastal markets may run 10%-25% above it because of labor rates, access constraints, and overhead.
Delivery is especially sensitive to distance and site access. A supplier close to the job may charge $250-$600 for a standard delivery, while a long route, special trailer, restricted road, or remote location can push the fee above $1,000. A crane may be needed when the truck cannot place trusses near the structure or when the roof is tall.
Quotes should identify whether regional taxes and local permit fees are included. Permit costs are often handled separately from fabrication and can range from about $100 to more than $1,000, depending on jurisdiction and project value. Some locations also require stamped engineering or inspections; those requirements can add fees and must be confirmed with the building department.
Use local delivered quotes rather than applying a national per-square-foot average to a remote or urban job. Assumptions: regional differences are approximate and reflect ordinary residential projects, not guaranteed local rates.
Three example quotes for different roof projects
The examples below illustrate how size and layout change a quote. They are planning figures rather than bids, and exclude roofing, sheathing, gutters, and finished ceiling work. The “average” total represents a midrange package with ordinary access and standard materials.
| Project | Truss quantity and type | Material and delivery | Setting labor and equipment | Estimated total |
|---|---|---|---|---|
| Detached garage | 12-16 standard trusses, 20-24 ft span | $1,000-$2,200 | $800-$1,800 | $1,800-$4,000 |
| 1,500-sq-ft home | 25-35 standard gable trusses, 24 in. spacing | $4,500-$8,500 | $3,000-$6,000 | $7,500-$14,500 |
| 2,400-sq-ft home | 35-50 mixed hip and specialty trusses | $8,000-$15,000 | $5,000-$9,000 | $13,000-$24,000 |
For example, a 1,500-square-foot home might receive a $6,200 fabrication quote, $500 delivery charge, and $4,000 for a framing crew and lift, for a total near $10,700. If the plan includes scissor trusses over a great room, that portion could cost more than the standard trusses and may require additional coordination.
Check that each bidder uses the same roof area, truss count, spacing, design loads, and installation scope. A total that excludes crane time or bracing can look lower while leaving substantial costs for later.
What removal, revisions, and site access add
New construction usually avoids removal charges, but replacement projects may need existing roof framing removed. Tear-off and disposal of old framing can add roughly $1-$4 per square foot, depending on access, weight, and disposal rules. If the structure is occupied or the roof must be temporarily protected from weather, the project may also need temporary covering or staged work.
Changes after fabrication can be expensive because trusses are made to a specific design. A drawing revision before production may cost $100-$500 or more, depending on the redesign. Reworking delivered trusses can cost several hundred dollars per affected member, while replacement pieces and extra freight may bring the added charge to $1,000-$5,000 for a larger correction.
Restricted access can trigger hand unloading, smaller delivery vehicles, or extra labor. A narrow driveway, overhead wires, soft ground, or a roof more than 20 feet high may require a different lift plan. Ask the supplier to inspect the site or confirm access assumptions before the order is released.
Resolve openings, ceiling heights, and roof geometry before fabrication to avoid costly replacement or field modifications. Assumptions: ordinary demolition rates and no structural damage discovered after removal.
How to lower a wood truss quote without weakening design
Keep the roof shape as simple as the architectural plan permits. Reducing unnecessary valleys, dormers, and one-off truss shapes can lower fabrication and installation time. Repeating standard trusses may also reduce engineering coordination and production complexity, but the designer must confirm that any layout change meets structural and architectural requirements.
Request at least three itemized quotes using the same plans and specifications. Compare truss type, lumber grade, load design, spacing, engineering, delivery, crane service, and setting labor. A quote that is $1,000 lower may omit bracing or installation, so compare the delivered and installed totals rather than the material number alone.
Provide final drawings early and verify dimensions before the supplier begins production. Confirm wall plates, bearing points, openings, and ceiling details with the builder and designer. Avoid paying for premium finishes or specialty shapes that the plans do not require; do not reduce lumber size, design loads, or connection requirements without written professional approval.
Scheduling can matter, too. Flexible delivery dates may help a supplier coordinate a load, while rush fabrication or a short-notice crane booking can add fees. Bundling truss delivery with other framing materials may reduce transport charges if the supplier can handle both in one trip.
The safest savings usually come from simpler scope, accurate plans, and complete quote comparisons—not from reducing structural specifications. A clear written scope makes it easier to spot excluded fees and keep the final bill close to the estimate.
