Roofing Calculator – Estimate Roof Size & Materials

A roofing calculator helps estimate the total roof area and the materials required for roofing projects such as shingles, tiles, or metal sheets. It is widely used by contractors, builders, and homeowners.

The calculation considers roof length, width, and pitch. Roof pitch increases the actual surface area, which is important for accurate material estimation.

For example, a roof measuring 30×20 feet with a pitch of 6 will have a larger surface area than a flat roof. This ensures you order the correct amount of materials.

This tool helps reduce material waste, save costs, and improve project planning efficiency.
