Roof shingles are sold by both the bundle and by the square. A square of shingles is the quantity needed to cover 100 sq. ft. of roof. 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.
How many bundles of shingles cover on a square? most of the time, if it is a three tab, 20yr shingle it takes 3 bundles, some thirty year shingles take 4 bundles, and most if not all 40yr and above take 4-5, because they ar â¦ e thicker, and there are less shingles per bundle.. hope this helps..
