How to calculate square feet of a roof.

How do you determine square footage of a roof.

Convert the area to roofing squares. Multiply the length by the width to arrive at. This would yield 1 3 next square your result. Multiply the length and width of each square or rectangle shaped plane.

Calculate each plane separately. Depending whether the roof area is measured horizontally possibly from a drawing or photograph a correction factor is necessary to determine the actual area of the roof. Measure the length and width of every roof plane or surface. 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.

Given pitch and a horizontal area measurement multiply the horizontal area by a correction factor corresponding to pitch provided in the table below to determine the actual area of the roof to be used in the roofing material calculator. To determine the number of squares on the gable roof above simply divide its total of 24 000 square feet by 100. Calculate the square footage of a gambrel style roof using imperial measurements. The result is 240 and this means you would need 240 squares of shingles to cover that roof.

How do you calculate square footage for a roof. The distance from the outside edge of a perimeter stud wall to the center of the house. Include dormers the small outjuttings over attic windows. For example if your roof s pitch is 4 in 12 you would divide 4 by 12.

Roof pitch is measured by rise run. Measure the ground dimensions of the house using a tape measure and write down these dimensions. L x w a in square feet to find square feet multiply the length measurement in feet by the width measurement in feet. If you don t want to do a lot of measuring you can use your pitch calculation to get an estimated square footage of your roof.

The distance from the top of a stud wall to the peak of the roof. The lower slope length is measured from outside wall to the start of the upper sloped roof section. Because each 100 square feet of roof is one roofing square divide. A square is an area of roof which measures 100 square feet.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
