Roofing Cost Calculator
Estimate the cost of a full roof replacement or repair based on your home's size, roofing material, and roof pitch. Figures reflect current typical U.S. installed pricing.
ESTIMATE YOUR ROOF
Average roofing costs by material
| Material | Cost per sq. ft. (installed) | Lifespan |
|---|---|---|
| 3-Tab asphalt shingle | $3.50 – $5.50 | 15–20 years |
| Architectural shingle | $4.50 – $7.00 | 25–30 years |
| Standing seam metal | $8.00 – $14.00 | 40–70 years |
| Clay / concrete tile | $10.00 – $18.00 | 50+ years |
| Flat roof (TPO/EPDM) | $5.50 – $8.50 | 20–25 years |
Roof pitch
Steep roofs need more material and safety equipment, adding 10–30% to labor cost.
Tear-off
Removing an old roof layer typically adds $1–$1.50 per sq. ft.
Region
Labor rates on the coasts run 15–25% above the Midwest and South.
Roof access
Multi-story homes or tight lot access can add 5–15% to labor.
How this calculator works
The estimate above is built from your home's footprint, the roofing material you select, and your roof's pitch. We convert your footprint into actual roof surface area using a pitch multiplier (steeper roofs have more surface area than their footprint suggests), then apply current national material-and-labor rates for your chosen material. If you check "tear-off," we add the typical cost of removing your existing roofing layer before the new material goes down. The result is a range rather than a single number because actual quotes vary with decking condition, local labor rates and the specific contractor you hire. If your project involves more than just the roof, check our junk removal, lawn care, tree removal or car insurance calculators as well.
What goes into a professional roofing quote
A roofing quote is really several line items bundled into one number. Material cost covers the shingles, metal panels or tiles themselves, typically 35-45% of the total. Labor covers the crew's time, usually the largest single component at 40-50%. Tear-off and disposal, underlayment and flashing, and permit fees round out the rest. Understanding this breakdown helps you evaluate whether a quote that seems high or low actually makes sense for your specific project, rather than just comparing bottom-line numbers between contractors. Our full roof cost breakdown guide walks through each line item in more detail.
Roofing cost by home size
| Home footprint | Approx. roof area (moderate pitch) | Architectural shingle cost |
|---|---|---|
| 1,200 sq ft | ~1,380 sq ft | $6,200 – $9,700 |
| 1,800 sq ft | ~2,070 sq ft | $9,300 – $14,500 |
| 2,400 sq ft | ~2,760 sq ft | $12,400 – $19,300 |
| 3,200 sq ft | ~3,680 sq ft | $16,600 – $25,800 |
Step-by-step: what a roof replacement looks like
- Inspection and measurement — a contractor confirms your roof's size, pitch and condition, including any decking issues.
- Material delivery — shingles, underlayment and flashing are staged on-site, usually the morning of the job.
- Tear-off — the old roofing is stripped down to the decking, the loudest and messiest part of the project.
- Decking repair — any soft or rotted plywood found underneath is replaced before new material goes down.
- Underlayment, flashing and installation — a water-resistant barrier, flashing at vulnerable points, then the roofing material itself.
- Cleanup and final inspection — a magnetic nail sweep and a walk-through with the homeowner.
Getting an accurate quote
This calculator gives you a realistic starting range, but an actual quote requires an in-person or satellite measurement. When you do request quotes, ask each contractor the same questions: is this price per-square or total, is tear-off included, what's the decking repair rate if needed, and is the measurement based on an actual walk of the roof or a satellite estimate. Comparing quotes built on the same assumptions makes it far easier to spot which one is genuinely competitive. You can also request free quotes directly through CostCheckPro once you have your estimate.
Why roofing material choice matters beyond price
The cheapest material per square foot isn't always the best value over time. Architectural shingles cost more than basic 3-tab shingles but last nearly twice as long, which usually makes them the better long-term choice even though this calculator's default setting reflects that higher upfront number. Metal and tile sit at a different point on the curve entirely — a much higher installation cost offset by 40+ years of service with minimal maintenance. See our metal vs. shingle roof comparison for a full side-by-side. If you're planning to stay in your home long-term, it's worth running this calculator with a few different materials to compare not just the sticker price but the cost per year of expected service.
Regional cost differences
| Region | Typical price adjustment | Why |
|---|---|---|
| Northeast | +15% to +25% | Higher labor rates, stricter permitting |
| West Coast | +15% to +30% | Labor costs, fire-rated material requirements in some counties |
| Florida / Gulf Coast | +10% to +20% | Wind-rated material requirements from hurricane building codes |
| Midwest / South (inland) | Baseline to -10% | Competitive labor market, lower overhead costs |
This calculator uses national averages as its baseline. If you're in a higher-cost region, expect your actual quotes to land toward the top of the estimated range or slightly above it; in lower-cost regions, quotes often come in near or below the bottom of the range.

When decking repair changes your total
This calculator's tear-off estimate assumes a standard tear-off with no major surprises. In practice, roughly one in five tear-offs uncovers at least some rotted or soft decking that needs replacing before new material can go down. Contractors typically price this separately, often $50-$80 per sheet of plywood replaced, since it's impossible to know the extent until the old roof actually comes off. Budgeting a 10-15% buffer above this calculator's estimate is a reasonable way to prepare for that possibility without assuming the worst case.
Roof warranties: what's typically included
Most roofing quotes bundle two separate warranties that are worth understanding before you compare prices. The manufacturer warranty covers defects in the material itself — premature cracking, granule loss beyond normal wear — and commonly runs 25-30 years, though often prorated so the payout shrinks with age. The workmanship warranty comes from the contractor, not the manufacturer, and covers installation errors like a leak caused by poor flashing work. These range from 1-2 years at smaller companies to lifetime coverage at larger, certified installers. A "lifetime warranty" in an ad almost always refers to the material warranty specifically, which is worth clarifying before you sign anything.
Financing a roof replacement
Few homeowners pay for a full roof replacement entirely out of pocket. Common options include contractor-offered financing plans, often with a 0% promotional period for 12-18 months; a home equity line of credit, which typically carries a lower interest rate but takes longer to set up; and insurance claims, which can significantly offset cost if the damage is storm-related. If a recent storm is involved, it's worth having your roof inspected and documenting any damage before assuming you'll need to pay the full replacement cost yourself.
Common mistakes to avoid
- Choosing the lowest bid without checking scope. A quote well below the others usually reflects a thinner spec or missing tear-off, not genuine efficiency.
- Skipping the permit. Unpermitted roofing work can complicate a future home sale when buyers' inspectors check permit history.
- Assuming the base quote is the final price. Leave room for decking repair, which is common enough that it shouldn't come as a complete surprise.
How roof age affects insurance and resale
A new roof does more than stop leaks. Many insurers now require inspection before issuing or renewing a policy, and roofs over 15-20 years old can trigger higher premiums or non-renewal. A documented new roof with a manufacturer warranty often qualifies for a modest premium discount. At resale, a roof nearing the end of its rated life is frequently negotiated off the sale price at close to full replacement cost, while a recently replaced roof is one of the few renovations that reliably recoups a large share of its cost, since buyers see it as one less thing to budget for.

Most residential roof replacements take 1–3 days depending on size, material and weather. Metal and tile roofs generally take longer than asphalt shingles.
Many roofing contractors offer in-house financing, and some homeowners use a home equity line of credit for larger jobs. Ask contractors directly about available plans.
Insurance typically covers roof damage from storms, hail or fire, but not normal wear and aging. A contractor can help document damage for a claim.
Because roofs are sloped, not flat, the actual surface area is larger than the home's footprint — often by 15-30% depending on pitch. Steeper roofs need proportionally more material.
Yes — getting three quotes is standard practice and helps you spot outliers, whether unusually high or suspiciously low, before committing to a contractor.
