A 32-foot attic truss typically costs about $700-$1,800 per truss for a custom-engineered unit, with a complete roof package often running $18,000-$45,000 before or including installation depending on quantity and scope. The price changes with lumber grade, attic room dimensions, roof pitch, engineering requirements, delivery distance, and whether the quote includes crane placement and labor.

What a 32-foot attic truss usually costs
A single 32-foot attic truss generally costs $700-$1,800 when purchased from a truss manufacturer, with a typical quote near $1,150. This is a planning range for a custom wood truss with a usable central attic area, standard residential loading, and ordinary roof geometry. It is not a guaranteed catalog price: manufacturers price from engineered drawings and local lumber costs.
For a full roof, a 1,500-square-foot footprint may need roughly 18-30 trusses, depending on building length, spacing, gable design, and framing plan. The truss material package commonly lands around $12,000-$38,000. A smaller garage or addition may require fewer units, while a larger house, heavier loads, or wider interior room can push the package above that range.
For initial budgeting, separate the truss price from delivery, crane placement, bracing, and roof framing. Quotes that appear far apart may include different scopes. Assumptions: U.S. residential construction, custom wood trusses, standard access, and no unusual snow, wind, or seismic design conditions.
How lumber, engineering, and labor shape the truss quote
Attic trusses cost more than basic roof trusses because their internal web layout must leave room for a usable space while still carrying roof and ceiling loads. The quote may include lumber, metal connector plates, fabrication, engineering, delivery, and installation as separate line items. The table gives typical planning ranges; an engineered supplier quote is needed for a buildable price.
| Quote component | Typical range | Pricing basis | What changes it | Usually included |
|---|---|---|---|---|
| Truss lumber and plates | $500-$1,350 per truss | Per fabricated unit | Span, lumber grade, room opening, roof pitch | Wood members and connector plates |
| Engineering and drawings | $300-$1,500 per project | Project fee | Complexity, revisions, local design loads | Truss design package or calculations |
| Delivery | $500-$2,500 per load | Distance and truck type | Haul miles, route access, load size | Transport to jobsite, not always unloading |
| Crane or boom placement | $800-$3,500 per day | Equipment and operator | Reach, setup, site obstacles, rental minimum | Lift service, sometimes operator |
| Set, brace, and labor | $2,500-$10,000 per roof | Scope and crew hours | Truss count, height, access, weather | Positioning, temporary bracing, fastening |
Labor is often estimated by crew size and job duration rather than by a fixed per-truss rate. A four-person framing crew may set and brace a straightforward package in 1-3 working days, while difficult access or roof geometry takes longer. A planning labor rate of $50-$100 per worker-hour can help compare bids, but local contractor pricing and included insurance or supervision vary.
Check whether engineering, unloading, and permanent bracing are included before comparing totals. A low material quote may exclude crane time, blocking, connectors, or the labor needed to make the roof stable during installation.
Why room width, pitch, and snow load change the price
The clear interior room width is a major cost driver. A wider usable attic opening leaves less room for structural webs, often requiring stronger or more complex members. Specify the required clear width and headroom, not only the building’s 32-foot outside span. A change of 1-2 feet in the room layout can alter the design and price, particularly when storage or finished-room loads are involved.
Roof pitch also affects both geometry and material. A 6:12 pitch is generally less demanding than a steeper 10:12 design with comparable span and loads, though the final effect depends on the complete plan. Roof openings for dormers, skylights, or chimneys can require special trusses and additional framing; even a few nonstandard units may add hundreds of dollars each.
Local design loads matter. In areas with substantial snow loads, high winds, or seismic requirements, stronger lumber, closer spacing, additional connectors, or engineering revisions can raise the package price by 10%-30% or more compared with a basic design. Truss spacing of 16 inches on center rather than 24 inches can increase the unit count by about 50% along a given roof run, although the engineer determines whether that spacing is appropriate.
Changes to span, attic clear width, or loading should be priced through revised engineering, not improvised in the field. A 32-foot span is a structural specification; the exact design depends on building dimensions, roof shape, support points, and applicable code loads.
What does a 32-foot attic truss roof cost installed?
Installed totals depend on whether “installed” means setting the trusses or completing the roof structure. A setting-only quote may cover delivery, crane service, placement, fastening, and temporary bracing, but exclude roof sheathing, fascia, insulation, and interior finish. For a typical 1,500-square-foot roof, trusses plus delivery and setting commonly total $17,000-$52,000 under the assumptions in the table.
Sheathing and additional roof framing can add several thousand dollars, while roofing shingles, underlayment, flashing, gutters, and finished attic work are separate scopes. Ask contractors to identify each included task. If a bid says “truss installation,” confirm whether it covers permanent bracing and connections to the walls or only lifting and positioning.
Existing-building projects can cost more than new construction. Limited access, a small staging area, utility lines, or the need to protect a finished home can require additional labor or specialized equipment. An attic conversion may also need structural changes below the trusses, stairs, insulation, electrical work, and inspections; those expenses should not be mistaken for the truss price itself.
When do delivery and crane charges add the most?
Trusses are long, bulky loads, so delivery cost depends on the manufacturer’s distance from the site, truck access, and unloading plan. A local delivery may cost $500-$1,000, while a long haul or a load requiring special routing can reach $1,500-$2,500. Some suppliers include standard delivery but charge extra for a second trip, a restricted delivery window, or a site where the truck cannot unload safely.
Crane or boom-truck service commonly adds $800-$3,500 for a day. A simple, low-rise house with clear access may need only a short lift, whereas a two-story structure, long reach, steep grade, or overhead obstacle can require more equipment and setup time. Confirm whether the rental minimum includes the operator and whether waiting time is billed separately.
Site readiness can prevent avoidable equipment and crew charges. Before delivery, clear the access route, prepare a level staging area, confirm the set sequence, and coordinate the framing crew. If a truck arrives before the walls are ready or the lift area is blocked, standby fees and rescheduling can add hundreds of dollars.
How regional labor rates affect 32-foot truss pricing
Regional pricing reflects local wages, building demand, lumber supply, transport distance, and climate-specific structural requirements. As a broad comparison, material and labor totals in lower-cost rural markets may be 10%-20% below a national-average planning estimate. Major coastal metros and high-demand construction markets can run 15%-35% higher, especially when crane operators and framing crews are booked tightly.
Weather and code requirements also create regional differences. Snow country may need designs for heavier roof loads, while hurricane-prone areas can require enhanced wind connections and documentation. These are not simple regional surcharges: the truss engineer calculates the required design for the actual site and building. Quotes should state the design load assumptions so the price comparison is meaningful.
Local delivery can offset some labor differences. A supplier farther away may offer a lower unit price but charge more for transport or require a larger order. Compare the delivered package total, not just the quoted price per truss, and check whether local sales tax, unloading, and permit-related engineering are included.
Three realistic quotes for different 32-foot roof scopes
These examples show how quantity and site conditions change the total. They assume custom wood attic trusses and U.S. residential construction; they are illustrative budgets, not fixed bids. The per-truss figure includes fabrication, while the remaining amounts represent separate project charges.
| Scenario | Truss quantity and unit price | Delivery and equipment | Labor | Estimated total |
|---|---|---|---|---|
| Detached garage, straightforward access | 12 at $850-$1,150, $10,200-$13,800 | $700-$1,500 | 2 workers, 12-20 hours, $1,200-$3,000 | $12,100-$18,300 |
| 1,500-sq-ft home, standard roof | 22 at $900-$1,300, $19,800-$28,600 | $1,300-$3,500 | 4 workers, 24-40 hours, $4,800-$10,000 | $25,900-$42,100 |
| Complex roof, limited crane access | 26 at $1,150-$1,800, $29,900-$46,800 | $3,000-$6,000 | 4-5 workers, 40-64 hours, $8,000-$16,000 | $40,900-$68,800 |
The labor figures use approximate loaded rates of $50-$100 per worker-hour and include setting and bracing, not roofing or attic finishing. The complex scenario may require engineered specialty units or additional site coordination. If a quote differs substantially, compare truss count, lumber grade, engineering scope, load assumptions, crane time, and exactly what the crew will install.
Which specification changes can lower the quote?
The most reliable savings come from agreeing on the attic layout and roof geometry before requesting final bids. Keep the clear room width and headroom requirements tied to actual use, avoid unnecessary dormers or unusual roof breaks, and have the designer confirm whether standard spacing and readily available lumber grades meet the project loads. Small design revisions after fabrication begins can trigger restocking, redesign, or replacement charges.
Request itemized bids from at least three suppliers or framing contractors using the same plans and specifications. Compare delivered price per truss, engineering fees, delivery distance, crane allowance, labor hours, and warranty terms. A quote that is 5%-10% lower may be a genuine savings, but a larger discount deserves a careful check for omitted unloading, bracing, or code-required connectors.
Control the scope before trading away structural capacity or required attic space. Do not reduce lumber size, connectors, or design loads without approval from the truss engineer and building authority. If the budget is tight, consider simplifying nonstructural features, scheduling delivery when the site is ready, or separating the attic finish from the roof-framing contract.
