What is Roof Pitch?
Roof pitch describes how steep a roof is. It shows how many inches the roof rises vertically for every 12 inches of horizontal run. For example, a 6:12 roof pitch means the roof rises 6 inches for every 12 inches of horizontal length.
Why Roof Pitch is Important in Construction
Understanding roof pitch is important for builders, contractors, and homeowners. It affects water drainage, roofing material selection, structural design, and overall building safety.
A steep roof drains water and snow faster. A low slope roof may require special waterproof materials.
How This Roof Pitch Calculator Works
This tool calculates the pitch ratio using the simple formula:
- Pitch Ratio = Rise ÷ Run
- Standard Roof Pitch = (Rise / Run) × 12
The result shows the roof pitch in the common “X:12” format used in construction projects.
