Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
Slope roof into sq ft.
The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
Multiply the roof length by the gable wall length 40 24 960 multiply this amount by the slope factor 960 1 1180 1073 28 the area of this roof 1073 3 sq.
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.
Roof is 6 12 pitch and measures at 2 400 square feet.
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.
Get your roof size by using this roof pitch calculator.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
So 2400 x 1 12 2 688 2 88 sqs added for pitch.
That gives you 5 590 square feet which is the actual area of the surface of the roof.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
Roof pitch is used to describe the slope or angle of the roof.
