Roof Square Footage Calculator Pitch

Roof pitch is used to describe the slope or angle of the roof.

Roof square footage calculator pitch. 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. A 12 in 12 pitch is a. 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. Dividing by 12 gives the ratio of inches in rise per distance.

Things you will need steel tape measure. 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. 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.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. The maths behind this number is that it is the square root of rise run 2 1. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Roof pitch is given as the number of inches in height change over the distance of one foot.

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.

The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. A roof with a 6 rise for every 12 run has a 6. You can also calculate roof pitch even without using a roof slope calculator. Divide your roof pitch by 12.

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 s pitch is determined by how much it rises vertically for every foot it runs horizontally. 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.
