how many square feet in one bundle of roofing
The surface area of a roof is measured in squares of shingles. Each square covers 100 square feet. However, when you buy shingles, they're usually priced per bundle. Calculate the number of bundles needed by measuring the roof's square footage (length X width). Divide that number by 100 to get the number of squares needed. Multiply the number of squares by 3 (in most cases) or the number of bundles it takes to equal one square. Again, in most cases 3 bundles = 1 square.
