About Roof Pitch
Roof pitch is the steepness of a roof expressed as a ratio of rise to run. A standard pitch is measured as the rise in inches for every 12 inches of horizontal run. Understanding roof pitch is essential for proper roofing material selection and installation.
Common Roof Pitches
- • 3/12 to 4/12: Low slope, special roofing required
- • 5/12 to 7/12: Standard residential pitch
- • 8/12 to 12/12: Steep pitch, excellent drainage
