How to Use the Roofing Estimate Calculator (Step-by-Step)

Using the calculator is simple and requires only a few inputs.

Add the labor cost per square foot charged by your contractor or the average rate in your area.

Step 4: Set Waste Factor

The waste factor accounts for extra materials needed due to cuts, overlaps, and errors. A default of 10% is common, but you can adjust it.

Step 5: Click Calculate

The tool shows a short progress indicator, then automatically scrolls to your results.

Step 6: Review Results

You’ll see:

• Adjusted total roof area
• Material cost
• Labor cost
