The below chart shows the relationship between roof pitch and the angle (in degrees) of a roof. A roof pitch is the slope of a roof, which is determined by how much the roof rises (in height) for every foot of horizontal distance (also called “run”).
The first column of the chart lists different roof pitches, ranging from a flat roof (with almost no slope or pitch) to a very steep roof. The second column shows the corresponding angle (in degrees) for each roof pitch. For example, a roof with a pitch of 4:12 (which means it rises 4 inches for every 12 inches of run) has an angle of 18.43 degrees.
The chart is useful for builders, architects, and homeowners who need to know the angle of a roof based on its pitch. For example, knowing the angle of a roof can help with installing solar panels or choosing roofing materials that are appropriate for the climate.
It’s important to note that the table only shows common roof pitches and angles. Roofs can have a wide range of pitches and angles, so the chart is not exhaustive, for better results you can use our roof pitch calculator. Additionally, the chart assumes that the roof is a simple gable roof, meaning it has two sloping sides that meet at a ridge. More complex roof designs, such as hip roofs or mansard roofs, can have different pitches and angles on different sections of the roof.
