Roof Pitch Calculator
A precise tool.
What is the Roof Pitch Calculator & How does it work?
Roof pitch is a measure of the steepness of a roof, typically expressed as a ratio of vertical rise to horizontal run. This ratio can be used to determine the angle of inclination and the amount of material needed for roofing projects.
The formula to calculate the pitch in degrees is given by:
theta = arctan(frac{rise}{run})
theta = angle of inclination in degrees, rise = vertical rise, run = horizontal run
Understanding roof pitch is crucial for selecting appropriate roofing materials and ensuring proper drainage.

Frequently Asked Questions
How do I measure the rise and run of my roof?
Measure the vertical distance from the eave to the ridge for the rise, and the horizontal distance from one side of the roof to the other for the run.
What is a typical roof pitch for residential homes?
A typical roof pitch for residential homes ranges from 4/12 to 7/12, which means for every 12 inches of horizontal distance, the roof rises 4 to 7 inches.
How does roof pitch affect energy efficiency?
A steeper roof pitch can improve ventilation and potentially increase energy efficiency by allowing better airflow through the attic space.
Can I use this calculator for flat roofs?
This calculator is designed for pitched roofs. Flat roofs have a minimal pitch, typically less than 2/12.
What materials are best suited for steep roof pitches?
Steep roof pitches are well-suited for materials like asphalt shingles, wood shakes, and clay tiles due to their durability and ability to withstand wind uplift.
