The Roofing Calculator is a free online tool designed to estimate roof surface square footage and asphalt shingle bundle counts. It allows you to perform these calculations quickly and accurately without manual computations.

Input the footprint base floor area of your roof along with the slope classification. Once you enter these values, the calculator will automatically compute and display the results instantly.

The Roofing Calculator uses the following formula to calculate your results: Roof Area = Base Area * Pitch Multiplier Bundles = Roof Area / 33.3 (typical coverage area of a single bundle) This formula is standard and widely accepted for these types of calculations.

Sure! Here is a practical example: A 2,000 sq ft base floor plan with a Medium pitch (1.118 multiplier) has a roof surface area of 2,236 sq ft, requiring 2,236 / 33.3 = 68 shingle bundles. This example demonstrates how the inputs are processed through the formula to yield the final results.

To use the Roofing Calculator, you need to enter: Roof Base Floor Area, Roof Slope / Pitch. These inputs help the tool calculate precise results tailored to your situation.

The Roofing Calculator outputs the following details: Total Roof Surface Area, Shingle Bundles Required. This comprehensive breakdown helps you understand the different aspects of the calculated figures.
