1 12 Roof Pitch Calculator

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.

1 12 roof pitch calculator.

Calculate rise pitch angle and slope from entered run animated scaled diagram inch. A speed square and level can be used to easily find the pitch of a roof. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

You ll need a level and a tape measure or ruler. 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. Set the level on the edge of the speed square as shown below then place the heel of the speed square on a rafter or gable edge of the roof. 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.

Pitch angle precision color. Mark a spot on the level 12 inches from one end. Pitch measurement method 1. The pitch of this roof is 4 8 12.

Roof pitch refers to the slope which the rafter creates. Roof angles and rafter plumb cuts. Use one of these three methods below to calculate your roof s pitch. It will use the current cost of wooden rafters based on the average price found at home improvement stores.

The triangle diagram will be re drawn to scale with all dimensions marked. The calculator above can handle much of this math. Measure with a speed square. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

Find the inverse tangent of the pitch to find the angle in degrees. Angle the angle of a roof is the same as the roof s slope except instead of being. Enter base length to calculate rise and diagonal for current pitch angle. Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.

Set bevel gauge directly from phone or tablet screen. Select inches to enter decimal inches or millimeters for metric. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. What degree angle is a 12 12 pitch roof.

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. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Divide the first part of the ratio by 12 to work out the pitch. Roof pitch calculator results explained.

Visit this page on your phone to directly measure pitch and angles. A 12 12 pitch roof has a pitch angle of 45.
