Roof pitch degree table.

Roof slope examples.

Measure the run length it is the horizontal distance between the roof ridge and the wall of the building. 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. If this isn t practical then perform the same measurement on the underside of the roof. Measure the rise of your roof.

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.

5 12 roof pitch 22 angle 22 62 degrees details. Roofing terminology for roof pitch are. 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. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.

To determine your roof pitch calculator. Thus pitch is typically greater in areas of high rain or snowfall. Understanding a roof s pitching can be quite tough if you are just getting started and working with a roofer can leave you a little bit unsure about what is being suggested with regard to the job there s so much to learn that it can become a bit baffling.

The slope of the roof on this modern pond side house allows the solar panels to take in as much energy as possible and lets rain water fall back into the pond to help with drainage around the house. The exact roof slope in degrees is given by the arctangent.

Calculate the rafter length substituting these values into the following formula.
