Standard roof pitch degrees uk.

The way pitch also known as roof slope is measured is rise over run. The most commonly used roof pitches fall in a range between 4 12 and 9 12. This steep pitch is also an essential ingredient of cottage style. Some of the most common roof pitch types are conventional slope type roofs designed with pitch ranging from 4 12 to 9 12.

In the uk the typical house has a pitch between 40 50 although 45 should be avoided. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12. The 12 inch run is considered standard in roof pitch or angle terminologies.

Roof pitch is the measurement of roof steepness. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Roof pitch and corresponding angles. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. So use the 12 inch level as a constant run and 18 inch ruler as a variable rise.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. These are utilized in residential applications. Roof pitch varies depending on culture climate style and available materials. Roof pitches exceeding the level of 9 12 or approximately 37 degrees are termed steep slope roofs.

A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. In the usa the range of standard pitches is anywhere between 4 12 and 9 12. Pitches above 9 12 are very highly angled and are designated steep slope roofs. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.
