And that s the number you were looking for.
Slope roof into sq ft.
Flat roofs if your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width.
So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having 1 350 square feet multiply 1 350 by 1 0541 to get 1 423 square.
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.
Roof pitch is used to describe the slope or angle of the roof.
And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier.
A roof with a 6 rise for every 12 run has a 6.
As an example if your overhang is 12 inches you ll add 2 feet to the overall length and 2 feet to the overall width of the house.
The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
So 2400 x 1 12 2 688 2 88 sqs added for pitch.
