What affects roof replacement cost?
- Roof size — The biggest cost driver. Measured in roofing squares (100 sq ft each).
- Material — Asphalt shingles are most affordable. Metal and tile cost 2–5× more but last longer.
- Roof pitch — Steeper roofs require more safety equipment and labor, adding 10–50% to cost.
- Tear-off — Removing old shingles adds $1–$2 per sq ft. Most areas require it by code after 2 layers.
- State — Labor costs in California and New York run 25–30% higher than Midwest states.
- Deck condition — Rotted or damaged decking adds $70–$100 per sheet of plywood replaced.

| Home size | Roof squares | Low estimate | Mid estimate | High estimate |
|---|---|---|---|---|
| 800 sq ft | 8–10 | $4,500 | $6,500 | $9,000 |
| 1,200 sq ft | 12–15 | $6,500 | $9,500 | $13,000 |

Shingle roof replacement cost estimator
Asphalt shingles are the most common roofing material in the US, accounting for over 70% of all residential roofs. The average shingle roof replacement cost in 2026 ranges from $6,000 to $17,000 for a typical 1,500–2,000 sq ft home, depending on shingle grade, roof pitch, tear-off and your location.
Architectural (dimensional) shingles are the most popular choice — they cost 20–30% more than 3-tab shingles but offer better durability, wind resistance and curb appeal. Use our shingle roof replacement cost estimator above and select either "3-Tab Asphalt" or "Architectural Shingles" to get your specific estimate.
Metal roof replacement cost estimator
Metal roofing is the fastest growing roofing category in the US. The average metal roof replacement cost ranges from $14,000 to $40,000 for a 1,500–2,000 sq ft home depending on the metal type. Steel panels are the most affordable metal option. Standing seam metal is the premium choice, offering the best performance and longevity but at a higher upfront cost.
While metal roofing costs 2–3× more than asphalt shingles upfront, the 40–70 year lifespan means you may never need to replace it again — making the total cost of ownership competitive with cheaper materials that need replacing every 20–25 years.
Flat roof replacement cost estimator
Flat roof replacement costs range from $8,500 to $18,000 for a 1,500–2,000 sq ft roof area. TPO (thermoplastic polyolefin) is currently the most popular flat roofing material due to its energy efficiency, ease of installation and 20–30 year lifespan. EPDM rubber is slightly cheaper and has been proven over decades of use. Select "Flat" for roof pitch and either TPO or EPDM in our flat roof replacement cost estimator above.
How a roofing quote is actually built
Roofers price in squares — one square is 100 square feet of roof surface. Knowing that makes an estimate readable, because the trade quotes each stage per square rather than as a single lump:
| Stage | Typical 2026 cost |
|---|---|
| Tear-off, single layer of asphalt | $100–$150 per square |
| Disposal of the old material | $40–$60 per square |
| Shingle installation labor | $200–$300 per square |
| Materials | $80–$250 per square |
| Underlayment | $0.10–$0.80 per sq ft |
| Decking repair | $2–$5 per sq ft, as needed |
| Ventilation work | Roughly $200–$700 |
Overall, standard architectural asphalt typically lands at $4.50 to $7.00 per square foot all in, and roughly 60% of the total is labor rather than material. That ratio explains why shopping for cheaper shingles moves the total less than homeowners expect — and why the crew doing the work matters more than the brand on the wrapper.
Note also that roof area is not house footprint. A steeper pitch means more surface and slower, more difficult work, so a 2,000 square foot house can carry considerably more than 20 squares of roof.
The line nobody can quote in advance
Decking replacement is the one item that cannot honestly be priced before the old roof comes off, because nobody can see the sheathing until then. A good contract handles this explicitly: a stated per-sheet or per-square-foot rate for replacement, and an agreement that you are shown the damage before it is charged.
Treat a bid that includes no decking provision at all with caution. It has either assumed perfect sheathing — unlikely on an older roof, particularly around valleys, chimneys and eaves — or it intends to raise the issue on the day, when you have an open roof and no leverage.
Ventilation is half the system
A roof is not only a water barrier. Without balanced airflow underneath it, an attic superheats in summer and accumulates moisture in winter, which shortens shingle life from below and can void manufacturer warranties.
Balance is the key word: intake at the eaves and exhaust at the ridge, in roughly matched amounts. Exhaust vents without adequate intake simply pull conditioned air out of the house instead of moving air through the attic. Common faults worth checking while the roof is open are soffit vents blocked by insulation, bathroom fans discharging into the attic, and several different exhaust types competing on one roof plane.
Since the attic is accessible and the trades are already on site, this is the natural moment to address insulation as well — our attic insulation cost calculator covers that, and baffles keeping insulation clear of the soffit vents are what let the two systems work together.
Why roofing over old shingles rarely pays
Adding a second layer avoids tear-off and disposal — a real saving of roughly $140 to $210 per square. Against that:
- Nobody inspects the decking, so any rot stays and keeps spreading.
- The new shingles follow the contours of the old ones, which shows.
- Trapped heat between layers shortens the life of the new roof.
- The next replacement costs more, because two layers have to come off.
- Most jurisdictions cap the number of permitted layers, and some manufacturers limit warranty coverage on overlays.
Full tear-off is the default for a reason. While the crew is up there, it is also the cheapest time to replace gutters if they are failing — our gutter installation cost calculator prices that.
Frequently asked questions
How accurate is this roof replacement cost calculator?
There is no validated accuracy figure for this estimator, and we will not invent one. Its rates come from published 2026 cost data and are maintained by hand, but they have not been measured against a body of real quotes. Treat the result as a planning figure and the range as the realistic spread, then get at least 3 quotes from licensed, insured roofers in your area for a firm price.
How do I estimate roof replacement cost?
To estimate roof replacement cost: measure your home's footprint in square feet, identify your roof pitch, choose your roofing material, and factor in tear-off of the old roof. Our calculator does all of this automatically — just enter your home size and make your selections above. Costs are expressed per roofing square (100 sq ft) in the industry.
Does the roof replacement cost estimator include labor?
Yes — all our estimates include both material and labor costs, adjusted for your selected US state. Labor typically accounts for 40–60% of total roofing cost and varies significantly by region.
How much does it cost to replace a roof on a 1,500 sq ft house?
The estimated cost to replace a roof on a 1,500 sq ft house ranges from $8,000 to $16,000 for architectural asphalt shingles, including tear-off of the old roof and labor. Metal roofing on the same house would cost $14,000–$30,000. Use our calculator above with 1,500 sq ft to get a state-specific estimate.
What is the roof replacement cost estimator for Ohio homes?
Ohio roofing costs are close to the US national average. A 1,500 sq ft Ohio home with architectural shingles and tear-off typically costs $9,500–$13,500 in 2026. Select Ohio in our state dropdown above for an Ohio-specific roof replacement cost estimate.
How do I calculate roof replacement cost per square foot?
Roofing cost per square foot depends on your material choice. Asphalt shingles run $3.50–$7 per sq ft installed. Metal roofing runs $8–$16 per sq ft. Tile costs $9.50–$20 per sq ft. These are applied to your actual roof area — which is larger than your floor area due to pitch. Our calculator applies pitch multipliers automatically.
