How Do I Figure Roofing 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.

How do i figure roofing squares.

However shingles are packaged in a way that they are light enough for the average person to carry around. 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. 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. 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.

You will need to express this size in terms of square feet. Steeper sloped roofs are considered more aesthetically pleasing and last longer. To calculate the number of squares or bundles you need you should consider using the measurement method. Conventional slope roof range between 4 in 12 and 8 in 12.

Then add 10 to the number to account for waste. 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. These benefits do not come cheaply though. This method is considered the most accurate but you will need to get onto your roof to complete it.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. 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. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.

Singles are often sold in bundles with three bundles equaling one roof square. To properly calculate how. A 12 in 12 roof can cost up to 50 more than a 4 in 12 roof. The first step in a free roofing estimate is measuring the roof dimensions.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Anything more than 9 in 12 is considered steep. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. A low slope roof is anywhere from 2 in 12 to 4 in 12.
