Roof Square Footage Calculator Pitch

The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.

Roof square footage calculator pitch.

A roof with a 6 rise for every 12 run has a 6. 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. The calculator cannot account for complex shapes based on a measurement of square footage alone. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

Here are the equations you may use to solve for the length of the slope and the rafter. Dividing by 12 gives the ratio of inches in rise per distance. To accurately calculate the area of your roof you must first determine its slope or pitch. Use the following formula which also describes a right triangle.

Roof pitch is used to describe the slope or angle of the roof. The maths behind this number is that it is the square root of rise run 2 1. 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. Rafter rise run this formula is from the pythagorean theorem.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Things you will need steel tape measure. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing.

You can also calculate roof pitch even without using a roof slope calculator. 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. As you begin to calculate various costs you will see that the cost is a result of the interplay of many different variables including roof area in terms of footage measurement of any roof extras like.

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. 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. Roof pitch is given as the number of inches in height change over the distance of one foot.
