Roofing Materials Calculator
Estimate how many roofing materials you'll need and the total cost based on roof area, material choice, and pitch. Adjust for waste and get instant results!
Roofing Material Types & Tips
- Asphalt Shingles: Popular, affordable, and easy to install. Suitable for a range of roof pitches but may not last as long as other options.
- Metal Sheets: Durable, lightweight, and great for rainwater shedding. Available in panels or tiles; may require professional installation.
- Clay Tiles: Long-lasting and offer classic aesthetics, but are heavier (ensure roof support is adequate).
Roofing Calculator Details
- Area Calculation: Surface area = length × width × roof slope factor.
- Roof Slope Factor: Accounts for surface increase with pitch. Estimated as
Slope Factor = √(1 + (pitch/12)²) - Waste Factor: Accounts for material waste due to cutting, overlapping, and installation errors.
- Cost Estimation: Cost = number of material units × price per unit.

| Roof Pitch (Slope) | Affects coverage area & material needs (low-slope vs steep-slope) |
| Roofing Material Type | Asphalt shingles, metal, tile, slate, wood shake, etc. |
| Location | Adjusts cost per sq.ft. based on country/state (e.g., California vs. Texas) |
| Add-ons | Flashing, underlayment, ice dam protection, ventilation, etc. |
