Roof Square Footage 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.

Roof square footage pitch.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. You will need to express this size in terms of square feet. 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.

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

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. Things you will need steel tape measure. Roof pitch is used to describe the slope or angle of the roof. 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 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. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. 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. 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. A 12 in 12 pitch is a steep 45 degree angle roof.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Get your roof size by using this roof pitch calculator.
