Roofing cost calculator
Roofing material cost calculator
Enter the roof area (measure it by address or use the roof square footage calculator), choose your state, and compare material-only costs with a typical waste allowance.
| Material | Waste | Material cost | Lifespan |
|---|---|---|---|
| Architectural shingles Laminated dimensional asphalt shingles — the most common U.S. roof. | 10% | — | 25–30 yrs |
| 3-tab shingles Flat single-layer asphalt shingles, lowest cost. | 10% | — | 15–20 yrs |
| Impact-resistant shingles (Class 4) Asphalt shingles rated for hail; may lower insurance premiums. | 10% | — | 30–40 yrs |
| Standing seam metal (steel) Painted 24-gauge steel panels with concealed clips. | 14% | — | 40–70 yrs |
| Corrugated / R-panel metal Exposed-fastener steel panels, common on barns and budget roofs. | 13% | — | 25–40 yrs |
| Stone-coated steel Steel panels with granule coating in shingle, shake or tile profiles. | 13% | — | 40–70 yrs |
| Metal shingles Interlocking steel or aluminum shingle-shaped panels. | 12% | — | 40–60 yrs |
| Concrete tile Heavy molded tiles; check framing for the added weight. | 15% | — | 40–50 yrs |
| Clay tile Fired clay barrel or flat tiles; very long life. | 15% | — | 50–100 yrs |
| Cedar shingles Sawn cedar shingles, smoother than shakes. | 13% | — | 20–30 yrs |
| Natural slate Quarried stone; heavy and very durable. | 15% | — | 75–150 yrs |
| TPO membrane Single-ply white membrane for flat and low-slope roofs. | 10% | — | 20–30 yrs |
| Modified bitumen Asphalt-based rolls, torch-down or self-adhered. | 10% | — | 15–20 yrs |
| EPDM rubber Single-ply rubber membrane for flat roofs. | 10% | — | 25–30 yrs |

How the calculation works
Roof surface area ÷ 100 = roofing squares. Squares × (1 + waste %) = squares to order. Squares to order × price per square × your state’s price level = material cost. Waste depends on the material: about 10% for shingles on a simple roof, more for tile, slate and metal with many cuts.
Labor typically costs as much as or more than the materials, and tear-off, disposal, permits and tax are extra — ask local contractors for a full bid.
