Roof slope style. Divide the rise by the run the run is 12. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Pitch has a basic range but it s not uniformly defined however the range from flat that is not perfectly flat but is sloped in order to drain water is up to 12 2 12.

A low slope roof is anywhere from 2 in 12 to 4 in 12. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. A flat roof has a slope of 2 in 12 or less. A 4 12 slope is enough to accommodate water runoff but is not suitable for regions that are affected by heavy snowfall.

To determine your roof pitch calculator. Roofing terminology for roof pitch are. Roof slope roof angle and pitch degrees. Most roof s have a pitch in the 4 12 to 9 12 range.

This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof. To see roof pitch to degrees equivalents. Roof pitch refers to the slope which the rafter creates. Conventional slope roof range between 4 in 12 and 8 in 12.

Conventional forms range from 4 12 9 12 and steep slope roofing is more than 9 12 and requires extra fasteners. There are two main categories of roofing. What is a roof pitch examples. However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.

A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof for roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain. The run always remains constant at 12 inches. Roof is 6 12 pitch and measures at 2 400 square feet so 2400 x 1 12 2 688 2 88 sqs added for pitch.

5 12 roof pitch 22 angle 22 62. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Get your roof size by using this roof pitch calculator. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
