How to figure square footage for roofing shingles.

A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. The number of squares determines the amount of shingles needed. In roofing terms a square is 100 square feet 9 3 meters. The shingle bundles will be plastic or paper wrapped bundles that are made to be light enough for a single person to carry.

Therefore divide your total area by 100 or 9 3 if you re using meters to get the number of squares. 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. So for instance if your total is 2 381 square feet that s approximately 23 8 squares or 24 squares rounded up.

A square of shingles will be the amount needed to cover an area of 100 square feet. For instance if the roof is 1550 square feet then it is 16 squares. 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. This means that if you are going to be using heavier shingles you will need to have more bundles to cover each square foot.
