Figuring Square Footage Of A Roof

A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.

Figuring square footage of a roof.

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. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.

Use this information if. However shingles are packaged in a way that they are light enough for the average person to carry around. 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. The top ridge will be shorter than the one of the gable roof but the four hips will add.

So continuing our example if you ve got a two story house with a total square footage of 2 700 square feet with each floor having 1 350 square feet multiply 1 350 by 1 0541 to get 1 423 square. Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy. With the area measurement you can learn the approximate cost of a new roof. 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. Calculate square footage for a roof by measuring and by performing some basic math equations. 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. 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.
