Understanding Roof Pitch in Ohio
Roof pitch is a crucial measurement in roofing, representing the vertical rise of the roof divided by its horizontal run. Though often compared to slope, they are not identical. In the United States, roof pitch is measured over a 12-inch (1-foot) run, indicating how many inches the roof rises over this distance. For example, a 7/12 roof pitch means the roof rises 7 inches for every 12 horizontal inches. In many other countries, roof pitch is expressed in degrees.
Roof pitch significantly influences various aspects of roofing, including cost, total roof area, and the type of materials used. It also impacts walkability and drainage efficiency, with steeper pitches being common in regions with high rainfall or snowfall.

Method One: Measure From the Roof
- Tools Needed: A 12-inch level and a tape measure.
- Step-by-Step:
- Hold the level perfectly level on the roof.
- Measure the height from the roof to the level 12 inches away from where it touches the surface; this is the rise.
- Example: If the level end is 4 inches above the roof at 12 inches away, the pitch is 4:12.
Method Two: Measure From the Attic
- Tools Needed: A 12-inch level and a tape measure.
- Step-by-Step:
- In the attic, hold the level perfectly level touching a rafter at one end.
- Measure the distance from the level to the rafter 12 inches away from where the level touches the rafter.
- Example: If the level end is 4 inches above the rafter at 12 inches away, the pitch is 4:12.
Method Three: Measure the Total Rise and Run
- Tools Needed: Knowledge of the total height of the peak and the roof’s width.
- Step-by-Step:
- Example: If the peak is 4 feet (48 inches) and the total roof width is 20 feet (240 inches), the run is 120 inches.
- Divide the run by 12 to get the multiplier (120 ÷ 12 = 10).
- Divide the rise by the multiplier to get the pitch (48 ÷ 10 = 4.8). The pitch is 4.8:12.
Method Four: Measure With a Speed Square
- Tools Needed: A speed square and a level.
- Step-by-Step:
- Set the level on the edge of the speed square.
- Place the heel of the speed square on a rafter or gable edge.
- Holding the tools level, locate the measurement on the speed square where it meets the rafter’s bottom edge to find the angle of the roof in degrees.
