Roofing Calculator

The Roofing Calculator helps estimate the total roofing material needed based on roof dimensions, pitch, and material type. It also provides an estimated cost.

Formula:

Total Roof Area (sq ft) = Roof Length × Roof Width × Pitch Factor

Squares Needed = Total Roof Area ÷ 100

Total Cost = Squares Needed × Cost per Square

How to Use the Roofing Calculator

  • Enter the roof length and width in feet.
  • Select the roof pitch from the dropdown menu.
  • Choose the roofing material type.

  • Specify the waste factor percentage to account for extra material.
  • Click "Calculate" to see the total area, squares needed, and estimated cost.

Why Use a Roofing Calculator?

  • Avoid underestimating or overordering materials.
  • Get accurate cost estimates for budget planning.
  • Plan for material waste due to cutting and adjustments.

FAQ

What is a roofing square?

A roofing square is a unit of measurement equal to 100 square feet of roofing material.

How does pitch affect roofing material needed?

Steeper roofs require more material due to the increased surface area caused by the slope.

Why is a waste factor needed?

Roofing materials need extra coverage due to cutting, fitting around structures, and installation errors.

Can I use this calculator for metal or tile roofing?

Yes, simply select the appropriate material type and enter the cost per square.
