How Do You Figure How Many Squares In A Roof

The number of squares determines the amount of shingles needed.

How do you figure how many squares in a roof.

You will need to express this size in terms of square feet. 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. When figuring the amount of shingles needed to roof a house you first convert the total square footage of the roof to squares a square represents 100 square feet of area covered by shingles. A square simply refers to a 10 x 10 square of roofing.

To find the squares divide the overall roof area by 100 and then round up. Next you will need to use a roofing materials calculator. The top ridge will be shorter than the one of the gable roof but the four hips will add to the ridge length. When calculating square footage for your roof always add at least 10 percent of the total to account for waste.

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. The answer is the number of roofing squares for the roof. Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet. Outside of the u s a degree angle is typically used.

This is simply 100 square feet of roof. Estimate the pitch of the roof. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.

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. Check that your footage measurements are within this range so you can start off on the right foot. Calculate the square footage area of a hip roof. Singles are often sold in bundles with three bundles equaling one roof square.

The only difference in this calculation to the one for a gable roof area is the amount of the ridge. The square footage of a hip roof area is identical to the square footage of a gable roof of the same size. For instance if the roof is 1550 square feet then it is 16 squares.
