Normal home roof pitch.

However you can only use this pitch with built up roofing or specialized synthetic roofing. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. Many manufactured home builders will even do 6 12 or 7 12 pitch roofs. For most home styles roof pitches fall in a range 4 12 a moderate slope up to 8 12 fairly steep.

The pitch of a roof is arrived at by dividing the vertical rise and its horizontal span or what people in the roofing industry would refer to as the slope. 3 5 12 pitch is 3 5 inches of rise per 12 inches of run. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Pitches above 9 12 are very highly angled and are designated steep slope roofs.

Gable roofs on ranch style homes can have a variety of pitches from low to steep. Roof pitches exceeding the level of 9 12 or approximately 37 degrees are termed steep slope roofs. These are utilized in residential applications. Hipped roofs are also common which offer a slightly different design and lower pitch.

Gable roofs offer the advantages of easily shedding rain and snow in cold climates. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. Examples of extreme slopes range from 1 4 12 almost flat to 12 12 sloping down at a perfect 45 degree angle. This home was thatched by dodson brothers image credit.

Roof pitch in layman s language simply refers to the steepness of the roof. On a single wide home the roof can be considered flat since it is typically under a 3 5 12 pitch. This steep pitch is also an essential ingredient of cottage style. Roof pitch is simply calculated as follows.

A 5 12 would be 5 inches of rise for 12 inches of run. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. So the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. The most commonly used roof pitches fall in a range between 4 12 and 9 12.

High and low pitch examples two examples at each end of the spectrum. If a roof increases in height by four inches for every foot of horizontal run it is considered to have a 4 in 12 pitch or just a 4 pitch talk in terms of pitches and you will always be understood in the roofing universe.
