Frequently Asked Questions
What is roof pitch?
Roof pitch is the steepness of a roof expressed as inches of vertical rise per 12 inches of horizontal run (e.g., 6/12 pitch means 6 inches rise per 12 inches run).
What is a common roof pitch?
Common residential roof pitches range from 4/12 (18.4 degrees) to 8/12 (33.7 degrees). Low slope roofs are 2/12 to 4/12, while steep roofs are 9/12 and above.
How to measure roof pitch?
Measure vertical rise over 12 inches of horizontal run using a level and measuring tape. Alternatively, use an angle finder for direct degree measurement.
