Two Side Slope Roof

Before taking any measurements you must first confirm that it s safe to walk on your roof.

Two side slope roof.

Also known as pitched or peaked roof gable roofs are some of the most popular roofs in the us. Roof pitch is the measurement of roof steepness. See also roof pitch crow stepped corbie stepped stepped gable. Take the measurement of the vertical.

Take a measurement of 12 inches using a level. Since it is half the span the angle of the roof would be 45 degrees. 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. If asphalt shingles are to be installed on a low slope roof special steps are required to avoid short roof life and roof leaks.

Low slope roofs are from 0 to 3 12 in pitch. The way pitch also known as roof slope is measured is rise over run. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain. Slopes greater than 18 12 are found on a frame roofs and some mansard style.

See low slope roofing. A gable roof with its end parapet walls below extended slightly upwards and shaped to resemble steps. 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 mansard roof also known as a french.

The result of joining two or more gabled roof sections together forming a t or l shape for the simplest forms or any number of more complex shapes. But most important is the roof pitch the angle or slope of the roof which can be expressed in fraction ratio or degrees and divides the rise by the span. The sides are all equal length and come together at the top to. Some sources consider low slope to include 3 12 pitch roofs.

Position your level against the roof until the bubble of the vial sits between two lines. In other words if a roof has a span of 4 meters and a rise of 2 meters the pitch would be 1 2 or one half of the pitch.
