How many square feet in a package of roof shingles.

A square of shingles will be the amount needed to cover an area of 100 square feet. With heavier materials a square might consist of four or five bundles each with fewer shingles than the normal bundle. However shingles are packaged in a way that they are light enough for the average person to carry around. This means that if you are going to be using heavier shingles you will need to have more bundles to cover each square foot.

Each square will need three bundles of shingles to cover it. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. This is simply 100 square feet of roof. To find the squares divide the overall roof area by 100 and then round up.

There are 29 standard shingles in a bundle. The number of square feet in a bundle is printed on the paper or plastic packaging that covers the bundle. A square simply refers to a 10 x 10 square of roofing. Shingles are packaged in paper or plastic wrapped bundles designed to be light enough for a person to carry so heavier shingles require more bundles per square.

Before placing shingles on a roof roofers determine the total area to be covered and divide by 100 the area of a square to determine the total number of bundles needed to complete the job. With the metric square each bundle contains 22 shingles. Roof shingles are sold by both the bundle and by the square. Each shingle is 13 1 4 inches by 39 3 4 inches and the square covers 99 98 square feet using 65 shingles.

A square of shingles is the quantity needed to cover 100 sq. Each plywood sheet is 4 x 8 feet or 32 square feet which coincidentally is almost exactly equivalent to the coverage of one bundle of traditional three tab shingles. Find the total square footage of your roof by multiplying the width by the length and then divide that number by 100 and you will get the number of squares you need to cover. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.

The shingle bundles will be plastic or paper wrapped bundles that are made to be light enough for a single person to carry.
