How Do I Figure Roofing Squares

A 12 in 12 roof can cost up to 50 more than a 4 in 12 roof.

How do i figure roofing squares.

In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. Conventional slope roof range between 4 in 12 and 8 in 12. Steeper sloped roofs are considered more aesthetically pleasing and last longer. Anything more than 9 in 12 is considered steep.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. These benefits do not come cheaply though. 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. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

Singles are often sold in bundles with three bundles equaling one roof square. To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof. The first step in a free roofing estimate is measuring the roof dimensions. You will need to express this size in terms of square feet.

Then add 10 to the number to account for waste. To properly calculate how. However shingles are packaged in a way that they are light enough for the average person to carry around. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square.

The answer is the number of roofing squares for the roof. A low slope roof is anywhere from 2 in 12 to 4 in 12. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. 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.

The calculator cannot account for complex shapes based on a measurement of square footage alone. 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. 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. Convert the area to roofing squares.
