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.
Tip: Always check with your local supplier for up-to-date prices and regional recommendations.
