Roof Square Footage Calculator Pitch

Use the following formula which also describes a right triangle.

Roof square footage calculator pitch.

To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area. Things you will need steel tape measure.

Rafter rise run this formula is from the pythagorean theorem. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing. A roof with a 6 rise for every 12 run has a 6. The calculator cannot account for complex shapes based on a measurement of square footage alone.

A 12 in 12 pitch is a. Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. The maths behind this number is that it is the square root of rise run 2 1.

The best part of a roofing calculator is that it offers a free insight into the total cost of the replacement roof project on a sq ft basis. Dividing by 12 gives the ratio of inches in rise per distance. Roof pitch is given as the number of inches in height change over the distance of one foot. The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Roof pitch is used to describe the slope or angle of the roof. 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. Here are the equations you may use to solve for the length of the slope and the rafter.

To accurately calculate the area of your roof you must first determine its slope or pitch. Divide your roof pitch by 12. You can also calculate roof pitch even without using a roof slope calculator.
