How To Figure Out Roof Pitch

To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

How to figure out roof pitch.

First measure 12 inches from one end of the level and make a mark. For more on calculating roof pitch and understanding how pitch and slope are different read on. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Marvel at your mathematical.

However if you have a more complex roof you may need to calculate pitch section by section. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. If you are trying hard to work out how to figure roof pitch measurements the calculator takes away all of those problems for you more or less instantly. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page.

The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need. Includes result for hip valley factor slope factor and the roof slope in degrees. 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.

To convert between american roofing ratios and pitch degrees follow these steps. Roof pitch calculator results explained. A 12 12 pitch roof has a pitch angle of 45. Here s an easy safe way to determine the pitch from inside your attic.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. 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. Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement.

If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter length. Divide the first part of the ratio by 12 to work out the pitch. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. After measuring the slope estimate the roof pitch by dividing the slope by 2 if you have a simple gable roof.
