How To Figure How Many Squares On A Roof

The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.

How to figure how many squares on a roof.

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. However shingles are packaged in a way that they are light enough for the average person to carry around. Next find the square footage of the metal roofing panels you want to use. 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.

To properly calculate how many bundles of shingles are needed to roof your home you need to calculate the total square footage of the roof and convert it to squares. Calculate the square footage area of a hip roof. Singles are often sold in bundles with three bundles equaling one roof square. The top ridge will be shorter than the one of the gable roof but the four hips will add.

A square represents 100 square feet of area covered by shingles. 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. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. The calculator cannot account for complex shapes based on a measurement of square footage alone.

Convert the area to roofing squares. Use our roof pitch calculator to find the pitch of your roof. You will need to express this size in terms of square feet. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100. To accurately calculate the area of your roof you must first determine its slope or pitch. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. The only difference in this calculation to the one for a gable roof area is the amount of the ridge.

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. The first step in a free roofing estimate is measuring the roof dimensions. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
