Roof Replacement Cost Calculator
Estimate the full cost to replace a roof — tear-off, disposal, new material, labor, accessories, and permit — as one transparent 2026 project range. No signup.

Most online roof-cost tools harvest your address and sell it to contractors. This one doesn't ask for anything — the numbers below are a transparent planning estimate based on 2026 national averages (material + labor), updated periodically. Always verify locally and get multiple on-site bids before committing.

This rolls tear-off, disposal, new material, labor, and accessories into one project total. It's a planning range, not a bid.
We don't ask for your address or sell your info — these are the actual numbers, shown.
Disposal of old roofing runs $1–5/sq ft; tile and slate cost more to remove (heavy).
Budget 10–15% contingency — tear-off often reveals rotten decking or other surprises.
Permit costs vary widely by jurisdiction; confirm with your local building department.
Get multiple on-site bids — only an in-person inspection gives a real price. Prices based on 2026 national averages.
How this calculator works
Replacing a roof is more than the new shingles. This calculator rolls the whole project into one range: tearing off and disposing of the old roof, the new material and its labor, the accessories that finish the job (underlayment, drip edge, ridge cap, pipe boots, flashing), the access and complexity surcharges, and an optional permit. It is built for homeowners deciding whether to replace, but it is accurate enough for a contractor to sanity-check a bid.
Where the money goes
The result is itemized on purpose. New material and labor is usually the largest line; tear-off and disposal is the next, and it grows with extra layers and heavier old materials; the accessories bundle is a per-square allowance rather than an itemized list. Stories, complexity, and region multiply the subtotal, and the permit is added as a flat line. A separate 10–15% contingency is suggested for the surprises that tear-off tends to expose.
The same prices as our cost-per-square tool
The material pricing here is the exact same 2026 dataset used by the roofing cost calculator — they share one cost module, so the two tools never disagree. If you only want cost per square by material, use that tool; if you want the full replacement project total, stay here. To estimate the shingle bundles themselves, see the shingle calculator.
No address, no lead selling
The dominant roof-replacement-cost sites are lead generators that harvest your address and sell it. This one asks for nothing and shows the math instead. It is a planning range, not a bid — get multiple on-site inspections before committing, because only an in-person look at your decking, flashing, and access produces a real price.
Why two same-size roofs can cost very differently
Two roofs with identical square footage can land at opposite ends of the range — or outside it. The estimate isn't arbitrary; it's a starting point that real conditions push up or down. The biggest drivers:
- Roof complexity and number of planes — a simple two-plane gable is fast; hips, dormers, valleys, and many small facets mean far more cuts, waste, and labor.
- Penetrations — every skylight, chimney, vent, and pipe boot has to be flashed and sealed by hand. A roof full of them costs more than a clean field of the same size.
- Wall and edge flashing details — sidewall and headwall flashing, step flashing, counterflashing, and tricky edges add skilled labor that area alone doesn't capture.
- Accessibility, pitch, and stories — steep roofs need fall protection and staging, and a three-story or hard-to-reach roof is slower and riskier to work and load than a single-story walkable one.
- Tear-off and disposal — removing the old roof and hauling it off adds cost, more so with multiple layers or heavy materials like tile and slate.
- Decking condition — rotten or delaminated decking discovered after tear-off has to be replaced, a common mid-job surprise (budget a contingency for it).
- Material grade and quality — within a category, a builder-grade product and a premium one with a longer warranty can differ substantially per square.
- Regional labor and material costs — crew rates, permit fees, and material availability vary widely by market, which is why the same roof costs more in a high-cost metro than a rural area.
Frequently asked questions
- How much does it cost to replace a roof?
- Replacing a typical 2,000 sq ft asphalt roof — tear-off, disposal, new architectural shingles, labor, and accessories — runs roughly $15,000–$31,000 at 2026 national averages before adjustments, with most simple single-story jobs landing in the lower half. Metal, tile, and slate cost substantially more. This tool returns a full-project range, not a single number, because the real price depends on access, complexity, and local rates.
- How much does roof tear-off and disposal cost?
- Tear-off and disposal typically run $1–$5 per sq ft for a single layer. Each additional layer adds about 50% more labor, and heavier materials cost more to remove and haul — clay tile and slate can nearly double the disposal cost versus asphalt. The calculator scales tear-off by both the number of existing layers and the weight of the material being removed.
- Does a steeper roof or taller house cost more to replace?
- Yes, on both counts. A steeper pitch means more actual roof area and slower, fall-protected labor. A taller house means harder access and more staging. The calculator adds a stories surcharge (about +10% for two stories, +20% for three or more) and a complexity multiplier for steep, cut-up roofs, on top of the pitch-driven area increase.
- Should I budget extra for surprises?
- Always. Tear-off frequently reveals rotten decking, failed flashing, or inadequate ventilation that has to be fixed before the new roof goes on. Budget a 10–15% contingency on top of the estimate — the calculator shows this as a separate suggested line so it does not hide inside the base number.
- Do I need a permit to replace a roof?
- In most jurisdictions, yes — a full roof replacement is permitted work. Permit cost varies widely: many areas charge a flat $150–$500, while others base it on a percentage of project value. The calculator includes a typical flat permit allowance you can toggle off; always confirm the exact requirement and fee with your local building department.
- Why do roof cost sites want my address?
- Because most of them are lead-generation businesses: your address and contact details are the product, sold to contractors who pay for the lead. This calculator collects nothing and sells nothing. The breakdown is shown in full so you can verify where every dollar comes from.
