Note: The rafter length is calculated from the eave to the ridge. Total roof area includes both sides of a gabled roof.
Introduction to Sloping Roof Calculators
A sloping roof calculator is an indispensable digital tool that helps homeowners, builders, architects, and DIY enthusiasts accurately determine critical measurements for pitched roof construction. Whether you're planning a new build or calculating materials for a roof replacement, understanding your roof's dimensions is fundamental to project success.
How to Use the Sloping Roof Calculator
Using a sloping roof calculator is straightforward, requiring just three basic measurements: Roof Span (horizontal width), Roof Rise (vertical height), and Roof Length (building length). Enter these values in meters and click Calculate to get your pitch angle, rafter length, and total roof area.
Understanding Roof Measurements
The pitch angle indicates steepness, rafter length helps determine timber requirements, and total roof area is essential for calculating tile, slate, or membrane quantities.
