How To Determine The Angle Of A Roof

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

How to determine the angle of a roof.

Calculate the tangent of the roof angle by dividing the roof height by the roof width. If you prefer to work the angle out the traditional way without our handy calculator you can use the following equations to find the length of the rafter and the slope. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Rafter height width from pythagoras remember that at school so.

Angle the angle of a roof is the same as the roof s slope except instead of being. The value displayed as the rise will be your x. Roof pitch is used to describe the slope or angle of the 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.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. If you re thinking about replacing your roof with a new one you will need a roof truss calculator. This online truss calculator will determine the all in cost of your truss based on key inputs related to the pitch width and overhang of your roof. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.

Roof pitch calculator results explained. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. Pitch tan angle where angle is the roof pitch expressed in degrees. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

The angle of your roof is calculated the same way you d work the angle of a right angled triangle. If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. Knowing the pitch of your roof is useful when designing an addition installing skylights or cutting new rake boards. For example if the height is 7 5 feet and the width is 15 feet the tangent of the roof angle is 0 5 because.
