Roof replacement cost calculator
Short answer
A roof replacement typically costs $5,000–$14,000 for an average asphalt-shingle roof (1,500–2,000 sq ft footprint) — about $4–$8 per square foot of roof area installed, including tear-off and disposal. Metal roofs run 2–3× more, and steep or cut-up roofs cost more in labor. Enter your roof size, pitch, and material above for an estimate.
Footprint is the ground area under the roof; pitch converts it to true roof area. Estimate covers materials, labor, tear-off, and disposal — get local quotes to finalize.
Replacement cost by house size
Architectural shingles, 6/12 pitch, one layer torn off, moderate complexity. Your quote varies by region and roof shape.
| Footprint | Roof area | Est. replacement |
|---|---|---|
| 1,200 sq ft | 1,342 sq ft | $8,486–$13,886 |
| 1,500 sq ft | 1,677 sq ft | $10,608–$17,358 |
| 2,000 sq ft | 2,236 sq ft | $14,142–$23,144 |
| 2,500 sq ft | 2,795 sq ft | $17,679–$28,928 |
| 3,000 sq ft | 3,354 sq ft | $21,214–$34,715 |
What drives roof replacement cost
A replacement is a new roof plus removing the old one, so the cost has three parts: the material and labor to install the new roof (priced per roofing square — 100 sq ft of actual roof area), the tear-off and disposal of the existing layers, and a complexity premium for steep or cut-up roofs that slow the crew down.
Because pitch increases the true roof area over the footprint, a steeper roof needs more material and carries more labor risk. Material choice is the other big lever — architectural shingles cost more than 3-tab, and standing-seam metal is two to three times either. Get two or three local quotes; this estimate is for planning, not a bid.

How much does a roof replacement cost?
Most asphalt-shingle roof replacements run about $5,000–$14,000 for an average home (1,500–2,000 sq ft footprint), or roughly $4–$8 per square foot of actual roof area installed, including tear-off and disposal of the old roof. Standing-seam metal costs 2–3× more. Your number depends on roof size, pitch, material, and how cut-up the roof is.
What is included in a roof replacement estimate?
A full replacement covers new shingles or panels, underlayment, flashing, drip edge and ridge cap, labor, and tearing off plus hauling away the old roof. Decking (plywood) repair, permits, skylights, and chimney work are usually extra and quoted after inspection.
Is it cheaper to roof over instead of tearing off?
Roofing a new layer over the old one skips the tear-off cost (about $1–$2 per sq ft), but it adds weight, hides deck problems, and most codes allow only two layers total. Tearing off to the deck is usually the better long-term value and lets the crew fix what’s underneath.
How much does it cost to replace a 2,000 sq ft roof?
For a 2,000 sq ft footprint at a typical 6/12 pitch with architectural shingles, a replacement (including tear-off) usually lands in the mid four figures to low five figures depending on your region and roof complexity. Use the calculator above for a tailored range.
Why is my roof replacement so expensive?
The biggest drivers are steep or complex roofs (more labor and safety staging), premium materials like standing-seam metal, multiple existing layers to tear off, and high local labor rates. Permits, new decking, and features like skylights or dormers add more.
