How to Measure Your Roof’s Pitch
- Measure a horizontal distance of 12 inches (from the outside edge of your roof directly up the slope). This is called the run of your roof.
- Make a marking at exactly 12 inches. You can use chalk, a pencil, or removable tape. Extend a level line from the 12-inch mark, suspended in air, that reaches back towards the edge of your roof.
- Measure the distance vertically from the end of the level line downwards towards the edge of your roof. This is called the rise of your roof.
- The rise (vertical measurement) over 12 inches of run (horizontal movement) determines the pitch of your roof. (For our general estimating purposes a LOW pitch equals 3/12-5/12, MEDIUM 6/12-9/12 and HIGH 10/12- 12/12)
