Roof Area Calculator
Calculate roof area for different roof types. Estimate materials needed for roofing projects and calculate costs based on roof dimensions and pitch.
Step 1: Roof Dimensions
Understanding Roof Area
Roof area calculation depends on dimensions, roof type, and pitch. Gable roofs have a simple rectangular area, while hip roofs require more complex calculations.
Step 2: Roof Details
About Roof Pitch
Roof pitch is expressed as a ratio of vertical rise to horizontal run (e.g., 6/12 means 6 inches of rise per 12 inches of run). Steeper pitches increase the actual roof surface area.

Roof Area Calculation Formula
Surface Area = (Length × Width) × Pitch Multiplier
The roof area is calculated by multiplying the base area (length × width) by a pitch multiplier that accounts for the increased surface area due to roof slope. Different roof types have different calculation methods.
