Roofing Material and Cost Estimator

Our calculator provides estimates based on standard industry calculations and average material costs. For exact pricing, we recommend getting quotes from local contractors as prices can vary by region, roof complexity, and current material costs.

Measure the length and width of each roof section from the ground. For pitch, you can estimate by measuring the vertical rise over a 12-inch horizontal run. If your roof has multiple sections, calculate each separately and add the areas together.

The material cost includes shingles, underlayment, nails, and other basic materials needed for a standard roof installation. It doesn’t include flashing, vents, ice/water shield, or other specialty items that may be needed for your specific roof.

The waste factor accounts for cutting and fitting materials around roof features like chimneys, vents, and valleys. A 10% waste factor is standard for simple roofs, while complex roofs may require 15-20%.

To get the best price, we recommend getting multiple quotes from licensed contractors. Our service can connect you with up to 3 local roofers who will provide free, no-obligation estimates for your specific project.
