Re-roofing typically costs $4-$12 per square foot installed, with a common asphalt-shingle project averaging about $7 per square foot. The final price depends most on roofing material, roof size and pitch, tear-off needs, and local labor rates; complex roofs or premium materials can push the total higher.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed re-roofing | $4 per sq ft | $7 per sq ft | $12+ per sq ft | Typical range across common residential materials and job conditions |
| Asphalt shingles | $4 per sq ft | $6 per sq ft | $9 per sq ft | Standard architectural shingles, installed |
| Metal roofing | $8 per sq ft | $12 per sq ft | $18+ per sq ft | Varies by panel type, finish, and detailing |
| 1,700-sq-ft roof | $6,800 | $11,900 | $20,400+ | Uses the installed range above; actual roof area may differ from home floor area |
What a typical asphalt re-roof costs per square foot
For a standard asphalt-shingle re-roof, homeowners commonly pay $4-$9 per square foot, or about $6,800-$15,300 for 1,700 square feet of roof surface. Around $6-$7 per square foot is a practical planning figure for architectural shingles, ordinary access, and a straightforward roof shape. A simple roof using basic three-tab shingles may fall near the lower end; higher-grade shingles and more involved work raise the quote.
Roofers often price by the “square,” meaning 100 square feet of roof surface. A quote of $600-$900 per roofing square is equivalent to $6-$9 per square foot. The measurement refers to the sloped roof, not the home’s interior floor area, so a 1,700-sq-ft house can have more than 1,700 square feet of roof.
For budgeting, use the measured roof area and compare quotes on the same tear-off, underlayment, flashing, and disposal scope. These ranges assume a typical residential asphalt-shingle installation and exclude major structural repairs or unusual code work. Assumptions: U.S. residential labor, standard materials, normal access, and no extensive deck replacement.
How shingles, labor, and tear-off shape the quote
A roofing estimate combines materials and installation with preparation, removal, and disposal. The exact allocation changes by contractor and roof design, but the ranges below show common line-item pricing for asphalt shingles on a typical home.
| Quote item | Typical price | Pricing basis | What changes the charge |
|---|---|---|---|
| Shingles and underlayment | $1.50-$3.50 per sq ft | Materials | Shingle grade, synthetic underlayment, and waste allowance |
| Installation labor | $2-$4 per sq ft | Labor | Pitch, height, roof shape, and crew access |
| Old roof removal | $1-$2.50 per sq ft | Labor and disposal | Number of existing layers and local dump fees |
| Flashing and ventilation | $300-$1,500 per project | Accessories and labor | Chimneys, valleys, skylights, and vent changes |
| Roof-deck replacement | $75-$150 per sheet | Materials and labor | Rot, water damage, and code requirements |
Some bids include flashing, starter strips, ridge caps, and cleanup in a single installed rate; others list them separately. Ask whether the quote covers a full tear-off, underlayment, drip edge, flashing replacement, haul-away, and permit fees. A low base rate can become less competitive if these necessary items appear later as extras.
Removal and hidden deck work are the line items most likely to change after shingles come off. Labor is commonly reflected in the per-square-foot rate, while repairs found during tear-off may be billed by sheet or under a written allowance.
How roof pitch, layers, and material change the price
Roof size is only one part of the estimate. A steep, tall, or cut-up roof takes longer to strip and install than a simple one-story roof, and specialty materials require different labor and accessories.
- Pitch and access: A roof steeper than 6:12, meaning a 6-inch rise for each 12 inches of horizontal run, may add roughly 10%-25% for extra setup, safety measures, and slower work. Very steep roofs can cost more.
- Existing layers: Removing one layer is generally less expensive than removing two. A second layer can add about $0.50-$1.50 per square foot in removal and disposal charges, depending on weight and local fees.
- Roof shape: Multiple valleys, dormers, skylights, and chimneys create more cutting and flashing work. Detailed roofs can run 10%-30% above a simple gable roof with the same measured area.
- Material choice: Installed asphalt shingles often cost $4-$9 per square foot, metal about $8-$18, and slate or tile commonly $12-$30 or more. Framing capacity, regional availability, and details affect these broad ranges.
- Deck condition: Replacing damaged sheathing may add $75-$150 per sheet, often for a 4-by-8-foot panel. The amount cannot always be confirmed until the old roofing is removed.
Confirm how the contractor measures pitch, waste, and extra shingle layers before accepting a per-square-foot rate. A quote should say whether the unit price applies to actual roof area, how much waste is included, and what repair rate applies if rotten decking is uncovered.
Regional labor rates from the Midwest to coastal markets
Roofing prices vary with wages, insurance, disposal charges, weather exposure, and the availability of crews. A comparable asphalt job may cost around 10%-20% below the national midpoint in lower-cost rural markets, while dense metropolitan areas can run 10%-25% above it. These are planning differences, not fixed regional price rules.
In the Midwest and parts of the South, straightforward asphalt installations may often land around $4.50-$8 per square foot. Northeast and West Coast quotes frequently fall around $6-$11 per square foot for similar scope, with urban labor and higher overhead contributing to the increase. Mountain and coastal locations may also require products or fastening details suited to local wind, snow, or fire rules.
Regional material availability can alter the comparison. Metal panels may be competitive where local suppliers stock common profiles, while tile or slate delivery can add expense in areas without nearby distributors. Permit requirements and disposal fees also differ by municipality.
Compare at least three local bids with matching material and removal specifications rather than comparing national averages alone. Assumptions: Broad regional differences are approximate; roof shape, contractor workload, and local code can outweigh the regional average.
How long a roofing crew needs on a typical home
A roofing crew of four to six workers may complete a straightforward 1,500-2,000-sq-ft asphalt re-roof in one to three working days. Tear-off, weather delays, steep pitch, multiple layers, and deck repairs can extend the schedule. Metal, tile, or slate installations often take longer because panels or individual pieces require more careful fitting.
Labor rates are not always shown as an hourly charge, but roofing labor may correspond to roughly $50-$100 per worker-hour after accounting for contractor overhead, insurance, and crew coordination. A homeowner should not assume that multiplying this rate by visible work hours reproduces the full bid: equipment, supervision, travel, and warranty obligations may be included in the installed price.
Scheduling can affect the quote when demand is high after storms or during a region’s busy season. Contractors may have less flexibility during peak months, while a planned replacement booked outside an urgent weather event can allow more time to compare schedules and pricing. Rain, cold, and wind can also limit safe installation days.
Ask for the estimated workdays and the plan for weather interruptions, not just a promised start date. The contract should clarify whether temporary protection, cleanup, and any return visit are included in the price.
Three sample quotes for different roof sizes and materials
These examples illustrate how the same per-square-foot price produces different totals as area and project scope change. They are estimates, not fixed bids; local rates, waste, pitch, and hidden repairs can change the final amount.
| Example | Scope | Rate | Estimated total |
|---|---|---|---|
| Small ranch | 1,200 sq ft, asphalt shingles, one layer removed, simple access | $5.50-$7 per sq ft | $6,600-$8,400 |
| Typical two-story | 1,800 sq ft, architectural shingles, tear-off, moderate pitch | $6.50-$9 per sq ft | $11,700-$16,200 |
| Standing-seam upgrade | 2,000 sq ft, metal panels, detailed flashing, removal included | $10-$16 per sq ft | $20,000-$32,000 |
For the two-story example, a contractor might estimate a three- to five-person crew for two to three days, depending on access and roof details. A sheet of damaged decking could add roughly $75-$150, while extensive repairs may require a separate written change order.
Use these totals to check quote arithmetic, then verify the roof area and inclusions before judging whether a bid is high or low. If a quote is far outside the applicable range, ask whether it includes premium materials, extensive flashing, multiple tear-off layers, or structural work.
Where homeowners can trim a re-roofing estimate
The most reliable savings come from controlling scope without omitting essential installation steps. Compare the same shingle grade, underlayment, flashing work, ventilation plan, tear-off, disposal, and warranty across bids. Request a detailed estimate with unit prices for decking repairs and any optional upgrades.
- Choose a standard shingle profile: Architectural shingles provide a common middle ground; premium impact-resistant or designer products may add about $1-$4 per square foot, depending on product and region.
- Limit unnecessary upgrades: Replace functional components only when inspection, condition, or code warrants it. Do not remove required flashing, ventilation, or water protection merely to lower the initial quote.
- Prepare access: Clear vehicles, patio furniture, and items near the house before work begins. Easier access can reduce delays, though it may not change a contractor’s fixed price.
- Schedule before an emergency: Planning ahead gives time to compare bids and avoid urgent storm-related work. Do not delay a roof with active leaks if that risks interior damage.
- Ask about a limited overlay carefully: Installing a new layer over one existing asphalt layer can cost less when local code and roof condition allow it, but it may hide deck problems and add weight.
Some contractors charge a minimum project fee, so a small roof may have a higher per-square-foot rate than a larger one. Bundling a small detached garage with the house roof can sometimes reduce mobilization costs, but only if the materials and timing fit the same job.
Keep necessary tear-off and water-management work in the base scope; negotiate material grade and optional work instead. A clear written allowance for hidden repairs protects both sides from surprise charges once the old roof is removed.
When a repair costs less than re-roofing
A repair can be more economical when damage is limited to a small area and the surrounding shingles remain serviceable. Replacing a few shingles may cost roughly $250-$800, while a localized flashing repair commonly runs $300-$1,000. A leak involving multiple roof planes, widespread granule loss, or recurring failures may call for a broader inspection rather than repeated patching.
Age matters, but it is not the only decision point. A typical asphalt-shingle roof may last roughly 20-30 years depending on product, ventilation, climate, and installation. If the roof is near the end of its expected life and needs several repairs, compare the repair quote with a full re-roof estimate, including future maintenance and the risk of interior water damage.
An overlay may reduce immediate labor and disposal charges, but it is not suitable for every roof. Local rules may restrict the number of layers, and soft decking, moisture damage, or uneven existing shingles can make an overlay a poor choice. A full tear-off costs more initially but lets the contractor inspect the deck and install new underlayment across the roof.
Compare the repair’s coverage and expected service life with the cost of a complete replacement, not just the upfront invoice. If a contractor recommends replacement, ask for photos of the damage, the roof-area measurement, and the specific reason repairs would not be durable.
