Roof Square Footage Pitch

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

Roof square footage pitch.

Divide your roof pitch by 12. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. It is often compared to slope but is not exactly the same. See the image below for more explanation on rise run and pitch.

Get your roof size by using this roof pitch calculator. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. 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.

Roof pitch is used to describe the slope or angle of the roof. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.

You will need to express this size in terms of square feet. Dividing by 12 gives the ratio of inches in rise per distance. The first step in a free roofing estimate is measuring the roof dimensions. Roof is 6 12 pitch and measures at 2 400 square feet so 2400 x 1 12 2 688 2 88 sqs added for pitch.

A 12 in 12 pitch is a steep 45 degree angle roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. The costs for foam roofing on a 1 100 1 500 2 400 and 3 000 square foot home are 7 535 10 275 16 440 and 20 550. 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.

In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. Foam roofing costs 4 50 per square foot installed and an additional 1 63 sf to remove the original roof bringing it to 6 85 per square foot to account for roof pitch.
