The cost to redeck a roof is usually $3-$6 per square foot, or about $5,100-$10,200 for a 1,700-square-foot roof. Final pricing depends on how much sheathing needs replacement, plywood thickness, roof access, tear-off work, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full roof redeck | $2,550 | $7,650 | $15,000 | 850-2,500 sq ft of roof area at roughly $3-$6 per sq ft |
| Installed roof sheathing | $3 per sq ft | $4.50 per sq ft | $6 per sq ft | Labor and standard materials; roofing tear-off may be extra |
| One 4-by-8-foot sheet | $75 | $110 | $160 | Installed; small jobs can have minimum charges |
| Partial decking repair | $300 | $900 | $2,500 | Several damaged sheets, with access and removal affecting cost |
Assumptions: Standard plywood or OSB, typical U.S. labor, and a sound roof structure without major framing repairs.
What does roof redecking cost for a typical home?
Most homeowners pay about $5,000-$10,000 to replace sheathing across a typical 1,500-2,000-square-foot roof. Smaller homes or partial replacements may cost $1,000-$4,000, while large or complex roofs can exceed $15,000. These estimates cover decking work, not new shingles or a full roofing system.
Budget by roof surface area, not the home’s indoor floor area. Roof pitch, overhangs, and additions make the roof larger than the footprint, and steep or hard-to-reach areas can increase labor. A roofer should measure the actual roof and specify the number of sheets in the quote.
How plywood, labor, and tear-off shape the quote
Decking quotes often combine sheet material, removal of damaged boards, installation, and debris handling. The table shows common ranges for a moderate job; contractors may bundle some line items into a per-square-foot rate.
| Quote component | Typical price | What changes it | Billing basis |
|---|---|---|---|
| OSB or plywood | $25-$60 per 4-by-8 sheet | Thickness, grade, and local supply | Per sheet |
| Installation labor | $1.50-$3.50 per sq ft | Pitch, height, access, and crew rates | Per sq ft or bundled |
| Removal of old decking | $0.50-$1.50 per sq ft | Fasteners, layers, and tear-off scope | Per sq ft |
| Disposal and equipment | $150-$600 | Dumpster size and hauling distance | Per project |
| Roofing labor rate | $50-$100 per worker-hour | Region and contractor overhead | Hourly or included |
Ask whether the price includes removal, fasteners, underlayment removal, and disposal. A 2-person crew working 8-12 hours at a combined labor charge of $100-$200 per crew-hour represents roughly $800-$2,400 in labor, before materials and overhead.
How roof size and sheathing thickness change the estimate
Roof size is a direct cost driver: each additional 100 square feet of decking generally adds $300-$600 at common installed rates. A 4-by-8 sheet covers 32 square feet, so a 1,600-square-foot roof takes about 50 sheets before waste, cuts, and extra material for irregular shapes.
Standard 7/16-inch OSB is often less expensive than thicker plywood or upgraded panels. Moving to 1/2-inch or 5/8-inch sheathing can add roughly $10-$30 per sheet in material, with local prices varying. Confirm the required thickness against existing framing, local code, and the roofing manufacturer’s specifications.
Damage scope matters as much as area. A few soft spots may be replaced sheet by sheet, but widespread rot, sagging, or water damage can point to problems with rafters or ventilation. Framing repairs are separate work and can add hundreds or several thousand dollars.
Can redecking be limited to damaged roof sections?
Yes. Replacing only unsound sheets can be more economical when the surrounding deck is dry, flat, and securely fastened. A small repair may cost $300-$900, while replacing 10-20 sheets commonly falls around $800-$2,500, depending on roofing access and whether shingles are already being removed.
Partial work is most cost-effective when the roof covering is already off for replacement. If a roofer must remove and reinstall shingles solely to reach isolated decking, labor and material matching can make a small repair less attractive. Ask for separate pricing for necessary repairs and optional full redecking.
What roofers charge for labor and removal time
A straightforward full redeck on a single-story home may take a 3-4 person crew one to two workdays, especially when the old roof covering is being replaced at the same time. Steep pitches, multiple roof levels, chimney details, or limited staging space can extend the job and raise labor charges by 10%-30%.
Scheduling can also affect cost. Emergency work after a leak or storm may carry a rush charge, while a planned redeck coordinated with a shingle replacement avoids a separate mobilization. Compare quotes using the same roof area, sheet count, thickness, and removal scope.
When disposal, permits, and decking upgrades add expense
Hauling old sheathing and roofing debris may cost $150-$600, with higher fees for heavy loads, remote locations, or multiple dump runs. Some jurisdictions require permits for structural repairs or roof replacement, often costing $100-$500; requirements and fees vary by city and by whether framing is altered.
Replacing rotten rafters, correcting ventilation, or adding code-required edge or structural details is not usually included in a basic decking allowance. Ask the contractor to list these as separate possible charges and to get approval before doing work beyond the agreed scope. Keep a 10%-15% contingency for concealed water damage.
Three reroofing quotes for different home sizes
These examples use installed redecking rates of roughly $3-$6 per square foot and exclude new shingles. They illustrate how roof size and scope combine; actual quotes depend on region, pitch, and site access.
| Scenario | Decking scope | Estimated total | Typical conditions |
|---|---|---|---|
| Small ranch | 850 sq ft, 12 sheets | $2,550-$4,200 | Accessible roof, standard OSB, limited removal |
| Mid-size home | 1,700 sq ft, full redeck | $5,100-$10,200 | Standard pitch, disposal included, minor repairs |
| Large, steep roof | 2,500 sq ft, full redeck | $10,000-$15,000 | Higher labor, thicker panels, difficult staging |
Use the sheet count and unit rate to test whether a quote is internally consistent. A quote that is much higher may include steep-roof labor, structural repairs, or removal that another estimate excludes; request an itemized explanation before comparing totals.
