Roof Square Footage Calculator Pitch

To accurately calculate the area of your roof you must first determine its slope or pitch.

Roof square footage calculator pitch.

Here are the equations you may use to solve for the length of the slope and the rafter. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing. Roof pitch is used to describe the slope or angle of the roof.

The calculator cannot account for complex shapes based on a measurement of square footage alone. Things you will need steel tape measure. Dividing by 12 gives the ratio of inches in rise per distance. Use the following formula which also describes a right triangle.

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 roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Roof pitch is given as the number of inches in height change over the distance of one foot.

Divide your roof pitch by 12. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. 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 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. 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. 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. A 12 in 12 pitch is a.

You can also calculate roof pitch even without using a roof slope calculator. A roof with a 6 rise for every 12 run has a 6. The maths behind this number is that it is the square root of rise run 2 1.
