Roofing Calculators
Convert roof pitch, check sloped area and estimate roofing material quantities. These roofing calculators connect simple roof geometry with editable product coverage and waste assumptions.
Available calculators
1 live toolCalculate related roof geometry and material quantities in one tool.
- Rise, degrees and percent slope
- Roof SF, squares and shingle bundles
- Underlayment and roof-edge materials
- Metal panels for supported simple roofs
Choose Gable, Shed, Simple Hip or projected Area Only; no structural roof design.
Open CalculatorDistinguish plan area from roof surface
Pitch increases roof surface area above its horizontal projection. Choose the supported roof type or enter known projected area, then use the actual specified coverage for materials.
Simple geometry does not provide an exact hip-roof metal-panel layout. Rafter/truss design, loading and flashing design are outside the tool.
Measure the full roofing system
A complete roofing takeoff reviews plans, details and specifications for insulation, underlayment, flashing, accessories and transitions as well as the main covering.
Use the free tool for a defined roof check; use drawing-based measurement where intersections, penetrations or multiple systems require a coordinated scope.
