Scissor trusses typically cost $150-$900 each for common residential spans, with larger or highly engineered designs reaching $1,500 or more. The cost of scissor trusses depends mainly on span, roof and ceiling pitch, lumber requirements, delivery distance, and whether the quote includes installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Factory-built scissor truss | $150 each | $450 each | $1,500+ each | Varies by span, design, and load requirements |
| Trusses per roof area | $4 per sq ft | $7 per sq ft | $12+ per sq ft | Truss supply only; roof area and spacing affect rate |
| Installed truss package | $8 per sq ft | $13 per sq ft | $20+ per sq ft | May include setting, bracing, and related framing |
| Crane rental | $400 per day | $900 per day | $1,800+ per day | Depends on lift capacity, access, and rental duration |
| Engineering or design work | $300 | $800 | $2,000+ | Complex loads or revisions can increase fees |
What a Scissor Truss Costs for a Typical Roof
A standard residential scissor truss often costs $250-$700 each for a span of roughly 24-40 feet and ordinary snow and wind loads. A compact, simple truss may be closer to $150-$300, while a long-span or steep-pitch design can cost $900-$1,500 or more per unit. These are supply prices, not necessarily the full framing bill.
For budgeting by roof area, scissor trusses commonly run about $4-$12 per square foot of roof area before installation. The lower end generally applies to straightforward designs ordered in quantity; the upper end reflects longer spans, special lumber, unusual geometry, or demanding local loads. The equivalent rate per floor area can differ because roof pitch changes the amount of roof surface.
For a typical 1,500-square-foot roof, a reasonable starting budget is $6,000-$18,000 for trusses alone. That estimate assumes standard residential framing, a conventional delivery route, and a design that does not require exceptional reinforcement. Installed framing can bring the total to approximately $12,000-$30,000, depending on labor, lifting equipment, bracing, and the scope included in the contractor’s bid.
Assumptions: U.S. residential construction, standard engineered lumber and connectors, ordinary site access, and pricing before roof sheathing or finish work.
How Lumber, Fabrication, Delivery, and Labor Shape the Quote
A truss quote can bundle several expenses or list them separately. Comparing bids requires checking whether the quoted amount covers the engineered design, delivery, crane or telehandler, setting, temporary bracing, and permanent bracing. A low unit price may exclude substantial job-site charges.
| Quote component | Typical range | What changes the price | Common billing basis |
|---|---|---|---|
| Lumber and metal connector plates | $150-$1,200+ per truss | Span, pitch, lumber grade, loads, and custom web layout | Per truss or package |
| Engineering and fabrication | $20-$100 per truss, or $300-$2,000+ per project | Design complexity, revisions, and local engineering requirements | Per unit or design fee |
| Delivery | $150-$800 per load | Distance, truck type, quantity, and unloading conditions | Per delivery |
| Crane or lift equipment | $400-$1,800+ per day | Reach, capacity, setup, and rental duration | Daily rental or contractor charge |
| Setting and bracing labor | $2-$6 per sq ft of roof area | Crew size, roof height, access, and truss count | Area, day rate, or project bid |
Material cost is influenced by the amount and grade of lumber needed to carry the design loads. A scissor truss has sloped bottom chords that create a vaulted ceiling, so its geometry and connections differ from a flat-ceiling truss. Engineering and fabrication costs are not always a separate line item; some manufacturers include them in the per-truss price.
Setting labor can be quoted as a per-square-foot rate or as a crew price for the job. At roughly $45-$90 per worker-hour, a four-person crew working 8-12 hours could represent $1,440-$4,320 in direct labor before equipment, supervision, and contractor overhead. The actual quote should specify whether bracing and corrections are included.
Check the scope line by line before treating two bids as comparable. One supplier may include delivery and engineered drawings while another prices only fabricated trusses. Ask whether the estimate includes sales tax, crane time, unloading, temporary bracing, and any return trip or waiting-time charges.
Why Span, Ceiling Pitch, and Snow Loads Change Scissor Truss Pricing
Span is one of the clearest price drivers. A 24-foot truss is often less expensive than a 40-foot version because a longer clear span can require more lumber, larger members, and stronger connections. Costs may rise sharply as a design approaches a manufacturer’s standard limits or needs special handling and transport.
Ceiling pitch also affects the geometry and engineering. A modest 3:12 ceiling slope may fit a relatively straightforward design, while a 6:12 or steeper bottom-chord pitch can change member forces and reduce available attic clearance. The top-chord roof pitch, bottom-chord pitch, and distance between them all matter; a vaulted ceiling does not have one standard cost premium.
Local loads set another important threshold. In areas with ground snow loads around 30 pounds per square foot or more, or higher wind exposure, the design may require stronger lumber or additional connectors compared with a low-load location. A manufacturer must use the project’s actual code criteria rather than a general national assumption.
Spacing can affect the number of trusses. At 24 inches on center, a 40-foot roof run needs approximately 21 trusses per roof side run, counting the ends; at 16 inches on center, it needs about 31. Closer spacing may increase the number of units and installation time, although the individual trusses may be lighter. Openings, girder trusses, hips, valleys, and concentrated loads add further design work.
Ask for the span, top-chord pitch, bottom-chord pitch, spacing, and design loads in writing. These specifications let a buyer compare equivalent proposals and catch bids based on different assumptions. A structural engineer or truss designer should approve changes to the roof framing; field alterations can compromise the engineered assembly.
How Long Installation Takes and What Crew Rates Include
A straightforward residential roof with 20-40 trusses may take a framing crew about one to two days to set, align, and brace, assuming the building is ready and equipment can reach the work area. A complicated roof, multi-level structure, or restricted site can require several days. These times do not include truss fabrication, which is scheduled separately.
Framing labor often falls around $45-$90 per worker-hour, though contractor pricing varies by region and includes more than wages. A crew bid may cover supervision, insurance, layout, lifting, temporary bracing, and overhead. A separate equipment charge of $400-$1,800 or more per day may apply when a crane or telehandler is needed.
Access and readiness can add cost even when the truss design is simple. A narrow driveway, overhead wires, soft ground, or limited staging space may require a smaller lift, extra setup, or additional handling. Delays caused by incomplete walls or weather can lead to crew standby charges or another equipment rental day.
Confirm the expected setting day and the charge for delays before delivery is scheduled. The building should be square, walls properly braced, and bearing locations checked before the trusses arrive. This reduces avoidable handling and helps the crew work within its planned equipment rental window.
Three Scissor Truss Quotes for Different Roof Sizes
The following examples show how scope and specifications can produce different totals. They are planning estimates, not fixed national prices, and assume standard residential access with no unusual structural repairs.
| Example | Specifications | Supply | Labor and equipment | Estimated total |
|---|---|---|---|---|
| Garage | 24-foot span, 12 trusses, 4:12 ceiling pitch | $2,400-$4,200 | $1,200-$2,500 | $3,600-$6,700 |
| One-story home | 32-foot span, 22 trusses, moderate snow load | $7,000-$12,000 | $3,500-$6,500 | $10,500-$18,500 |
| Wide living space | 40-foot span, 26 trusses, steeper vaulted ceiling | $15,000-$28,000 | $5,000-$9,000 | $20,000-$37,000 |
In the garage example, the unit price is about $200-$350 per truss before setting. The home example works out to roughly $320-$545 per truss supplied, while the wide-span example reaches about $575-$1,075 each because its longer span and ceiling geometry demand more material and engineering. Roof area, number of trusses, and design loads are not identical across the cases.
The wide-span example shows why a per-truss comparison alone can be misleading. A buyer should compare the total installed package and confirm whether taxes, delivery, design, bracing, and roof sheathing are included. Sheathing and finish materials are generally separate unless the proposal explicitly bundles them.
Regional Delivery and Weather Loads Behind U.S. Price Differences
Local manufacturing availability, labor rates, shipping distance, and code loads create regional variation. A quote in a major metro area or a high-cost coastal market may run 10%-25% above a comparable rural or lower-cost market. Rural locations can still be expensive when the nearest truss plant is far away or a special delivery truck is required.
In snow-prone parts of the Northeast, Upper Midwest, and mountain regions, designs can cost 10%-30% more than a similar low-load design when snow loads require added capacity. In hurricane- or high-wind areas, required connections and uplift resistance may also raise material and installation costs. These percentages are broad budgeting comparisons, not a substitute for a project-specific design.
Delivery distances of more than 50-75 miles can add several hundred dollars, especially for oversized loads or limited delivery windows. Some suppliers set a minimum order or charge for a second trip if trusses cannot be unloaded when the truck arrives. Ask the supplier for a delivered price to the actual site rather than assuming the listed unit rate includes freight.
Use the local building department’s load requirements when comparing regional quotes. Two designs with the same span may not be equivalent if one is engineered for a different snow, wind, or exposure condition. A local contractor can also identify whether permits and inspections are billed separately from framing.
Scissor Trusses Compared With Rafters and Standard Roof Trusses
Standard roof trusses with flat bottom chords are usually the lower-cost option when a flat ceiling is acceptable. They may cost around $100-$500 each for common residential designs, though size and loads can push prices higher. A scissor truss commonly carries a 20%-50% premium over a comparable standard truss, but the difference varies with span and ceiling pitch.
Rafter framing can preserve more flexibility for unusual roof shapes, but it requires more on-site layout and carpentry. Installed rafter framing may cost about $10-$25 per square foot of roof area, depending on lumber, labor, and complexity. It is not automatically cheaper than a factory-built scissor truss, particularly when the roof has a broad span or needs extensive structural support.
A scissor truss provides a sloped interior ceiling without framing every roof member individually on site. Its drawback is that the bottom chord slope usually leaves less usable attic space than a flat-bottom truss. If a vaulted ceiling is not essential, asking a designer to price a conventional truss alongside the scissor option can reveal whether the architectural effect justifies the added expense.
Compare options using the finished ceiling, structural span, and usable storage—not just the lumber quote. Changing to a standard truss may require redesigning the ceiling or interior layout, while switching to rafters can alter labor and inspection requirements. Any substitution should be reviewed by the designer and building official.
Ways to Lower a Scissor Truss Quote Without Changing Safety
Keep the design close to standard dimensions where the building plan allows. Standard spans, common spacing, and widely available lumber grades can reduce custom fabrication and engineering time. Small changes to roof geometry should be reviewed early, before drawings are finalized and trusses are ordered.
Request a complete delivered-and-installed bid from at least two suppliers or contractors. Ask each to state the same span, pitches, spacing, loads, and included services. Compare unit pricing, delivery fees, crane days, and bracing separately; a quote that is $30 cheaper per truss can still cost more if it excludes freight or equipment.
Prepare the site to avoid extra handling. Provide clear access for the delivery vehicle, confirm a safe unloading area, and ensure walls and bearing points are ready for setting. Coordinate delivery with the framing crew so the trusses do not sit on site or require another move. Avoid rush orders when possible, because expedited design or delivery can add several hundred dollars or more.
Choose upgrades only when they serve a stated structural or design need. A steeper vaulted ceiling, longer clear span, or unusual overhang may increase lumber and engineering costs; changing these details can reduce the quote if the plans and intended interior remain workable. Do not cut truss members or alter connector plates to save money, since modifications require approved engineering.
The most reliable savings come from simplifying the approved design and preventing delivery or labor delays. Keep the roof drawings coordinated, verify code loads before ordering, and confirm in writing who pays for revisions, storage, standby time, or a failed delivery. That approach can lower avoidable charges without weakening the roof structure.
