That s a 7 12 pitch the roof gets 7 inches higher for every 12 inches of run toward the peak. On the other hand a roof with a ratio of 9 12 or a roof that rises nine inches for every 12 inches covered is considered a very steep slope.

In snowy areas your roof should be at least 10 12 40 to allow snow to shed while the safest roof pitch in very windy areas is between 4 12 6 12 18 5 26 5. What to consider with roof pitch. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Roof pitch is the angle of your roof or its slope.

For example 2 12 means a roof that rises two inches for every 12 inches covered. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. Steeper slopes increase the sail effect that makes them susceptible to wind.

In roofing the pitch is usually referred to as a ratio. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Pitches above 9 12 are very highly angled and are designated steep slope roofs. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

Water your biggest roofing concern in texas is likely water or storm damage. However you can only use this pitch with built up roofing or specialized synthetic roofing. The most commonly used roof pitches fall in a range between 4 12 and 9 12.

Pitch also impacts how well your roof dispatches water and handles debris. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12.

Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.
