Understanding This Calculator
Roofing Formulas
Calculate roof geometry.
- Pitch = Rise / Span
- Slope Angle (θ) = arctan(Pitch)
- Actual Area = Plan Area / cos(θ)
Example 1
Plan: 100 m², Rise: 2m, Span: 8m (Pitch=0.25)
- Angle ≈ 14°
- Area = 100 / cos(14°) ≈ 103 m²
How to Use
- Enter plan dimensions.
- Enter rise and span for pitch.
