This tool will calculate the slope of your roof to help you with design and construction planning.
How to Use the Pitch of a Roof Calculator
To use this calculator, input the dimensions and selections for your roofing project:
- Run Length: Enter the length of the run, which is the horizontal distance covered by the roof from the edge to the highest point.
- Rise Height: Enter the vertical height of the roof from the base to the apex.
- Roofing Material: Select the type of material you are planning to use. This is important as different materials can have different coverage areas due to their weight and handling specifics.
- Rafter Spacing: Enter the spacing between rafters in inches which determines the load and distribution across the roof.
Explanation of Results
This calculator provides the following results:
- Roof Pitch: The slope of the roof in inches per foot.
- Rafter Length: The length of each rafter required, based on the rise and run inputs.
- Total Roof Area: The total surface area of the roof that needs to be covered.
- Estimated Material Area: The adjusted coverage required based on the selected roofing material.
Limitations
Please note that this calculator provides estimates only. Other factors such as overhangs, waste, and local building codes can affect material requirements. It is advisable to consult with a roofing professional for a comprehensive assessment before proceeding with your project.
