Homeowners typically pay for both roof decking replacement and new shingles, with costs driven by deck material, shingle type, roof size, and labor. The price range reflects regional labor rates, material choices, and whether additional repairs are needed. This guide provides practical pricing in USD with clear low–average–high ranges and per-unit estimates for budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Roof Size (sq ft) | 1,000 | 1,800 | 3,000 | Includes attic access and debris removal baseline |
| Decking Replacement (Plywood 1/2″–5/8″) | $2.00 | $3.50 | $6.50 | Per sq ft; assumes failing decking requires full replacement |
| Shingles (Asphalt) | $1.80 | $3.25 | $4.75 | Per sq ft including underlayment and starter course |
| Labor, Roofing Crew | $1.50 | $3.00 | $5.00 | Includes tear-off, decking, and installation |
| Permits & Codes | $0 | $300 | $1,000 | Depends on locality and project scope |
| Disposal / Debris | $0 | $150 | $750 | Dump fees and haul-away |
| Misc. Materials | $100 | $400 | $1,000 | Underlayment, ice/water shield, nails, sealants |
| Total Project Range | $4,000 | $9,000 | $22,000 | Assumes 1,800–2,500 sq ft roof with standard pitch |
| Per Sq Ft Range | $2.20 | $5.00 | $9.50 | Costs vary by region and material choices |
Assumptions: region, roof size, pitch, material selections, and labor hours.
Overview Of Costs
Typical cost range for a full replacement of deck boards and asphalt shingles generally falls between $4,000 and $22,000 for 1,800–2,500 sq ft, depending on deck condition, roof pitch, and local labor rates. Low end usually reflects partial decking salvage with economy shingles or small roofs; high end involves extensive decking replacement, premium shingles, and higher labor costs in metropolitan areas. Per-square-foot pricing commonly spans $2.20 to $9.50, with additional fees for permits or specialty components.

What Drives Price
Roof pitch and decking condition are primary drivers. Steeper pitches increase labor time and safety requirements, while damaged decking necessitates replacement materials and more crew days. Shingle type and thickness—asphalt, architectural vs. 3-tab, and premium designer shingles—greatly affect material costs and warranty terms. Per-unit thresholds include decking at 1/2″–5/8″ plywood and shingles with 30-year or 50-year warranties.
Ways To Save
Compare bids across qualified local roofers to gauge region-specific pricing and scope. Consider coordinating decking replacement with routine maintenance to bundle labor. Using standard asphalt shingles instead of premium options typically reduces costs by 20–40%. In some markets, scheduling in spring or autumn avoids peak-season price spikes.
Regional Price Differences
Prices vary by region due to labor density, permit costs, and material availability. In the Northeast, total project costs may be 5–15% higher on average than the national baseline. The Midwest often shows more consistent pricing with moderate labor-rate differences. The West Coast can be 10–20% higher, driven by higher crew rates and stricter permitting. Regionally, expect plus or minus 10–15% deltas from the national averages for decking and shingle costs.
Labor & Installation Time
A typical roof deck replacement plus shingle install takes 2–5 days for an 1,800–2,500 sq ft roof on a standard-angle home. Labor costs reflect crew size, safety equipment, and waste disposal. Higher pitch or complex roof lines extend time and cost, while simpler roofs with conservative debris disposal stay closer to the average range.
Additional & Hidden Costs
Possible add-ons include ice-and-water shield along eaves, ridge vents, and flashing replacement. Permits can add several hundred dollars, and disposal of old decking adds a per-load line item. Unexpected deck damage or rot discovered during tear-off can raise costs substantially, sometimes by 20–40% of the deck portion.
Real-World Pricing Examples
Basic scenario: 1,800 sq ft roof, standard pitch, 1/2″ plywood decking, economy asphalt shingles. Materials and labor approximate $4,000–$6,500; total with minor permits around $4,800–$7,200.
Mid-Range: 2,100 sq ft, architectural asphalt shingles, 5/8″ decking, mid-range underlayment. Project price near $7,000–$12,000; per sq ft around $3.50–$5.50.
Premium scenario: 2,400 sq ft roof, premium shingles, full decking replacement, enhanced ventilation and ice/water shield. Total costs commonly $12,500–$22,000, with per sq ft $5.20–$9.00.
