Roof Picth Mulitpier

A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof.

This roof pitch table displays a multiplier for adding for different roof pitches. A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof. Then proceed to draw the surface area of the roof that has a different pitch. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

The maths behind this number is that it is the square root of rise run 2 1. If you know the pitch of a roof you can use the numbers in the following pitch table to do the following. How to find your what roof pitch category. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.

Simply multiply this number by the area covered by a sloped roof to obtain the total surface area of the roof itself. Determine how many square feet of roof area a building has by measuring from the ground. If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12. 100 1 054 105 4ft2.

First find the slope by finding the tangent of the degrees eg. For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. Degrees to pitch rise in run determine the area of the roof s footprint which is the area covered by the roof regardless of slope or the apparent area of the roof when you look straight down at it like from a satellite. Then multiply the slope by 12 to get the rise.

After drawing the perimeter of the roof add a new drawing layer with the plus symbol found in the bottom right corner. How to convert angle in degrees to roof pitch. For example a 4 12 pitch roof that is 100 square feet. If the roof has multiple pitches such as those found on dormer windows or porches you will need to draw these separately.

The roof pitch multiplier is a number that allows you to find the total surface area of your roof. The roof pitch multiplier is responsible for giving an accurate pitch measurement of the roof.
