Roof Area Calculator Introduction

This calculator is specifically designed for architectural design to quickly compute key parameters of roof areas (sloped roofs), including roof length, rafter length, rise height, area, volume, etc., assisting construction workers, designers, and property owners in accurately estimating material quantities and construction plans.

Roof Area Calculator Formulas

Roof Length = √((Width/2)² + Rise Height²)
Rafter Length = Roof Length
Rise Height = (Width/2) × tan(Roof Angle) or (Width/2) × Roof Pitch Ratio
Roof Area = 2 × Roof Length × Roof Width
Roof Volume = Roof Area × Roof Thickness
