Measure Roof Pitch Distance

The rise is the distance from the top of the roof to the bottom.

Measure roof pitch distance.

Find the inverse tangent of the pitch to find the angle in degrees. Measure the vertical distance from roof to level. The use of a 48 inch carpenter s level or a straight 2x4 board may be useful to create a smooth surface that mirrors the slope of the roof. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.

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. While run is the level distance among the crest of the roof as well as the wall rise is the elevation of the peak over the wall. Hold the 0 mark of the tape measure against the roof. Angle the angle of a roof is the same as the roof s slope except instead of being.

Note the vertical distance on the tape measure and write this value down. Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark. Extend it upward so it is perpendicular to the level. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.

A 12 12 pitch roof has a pitch angle of 45. Check your results with the omni roof pitch calculator. Marvel at your mathematical. 8 inches and you have an 8 in 12 pitch.

Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Roof pitch calculator results explained. When the matter is of calculating the roof pitch of your house it can be done in two ways.

If this distance measures 4 inches you have a 4 in 12 pitch. The run is the distance from the outside of the wall to the inside of the ridge. Roof pitch is used to describe the slope or angle of the roof. The pitch highest point of the roof is an important ratio when measuring the truss.

Occasionally you could even calculate the span. A roof that rises 1 inch for every 4 inches of its horizontal distance has a 1 4th pitch. This is basically the distance among the walls. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.

A sample calculation would be. To convert between american roofing ratios and pitch degrees follow these steps. In roof pitch calculator pitch value can be obtained by dividing n by. Divide the first part of the ratio by 12 to work out the pitch.
