How to Calculate Area for Shingles

Hi, this is Jon on behalf of Expert Village. In this video clip we'll be calculating shingles. To calculate the number of bundles of shingles for a basic gable roof first we need to measure the length and the width of the rectangular areas that is adding incline on the roof. For this particular roof we're going to say that it's 44 feet X 16 feet. So we would get a total square footage for one side to be 704 square feet however, since we needed to do both sides we're going to multiple it that by 2 and get 1408 square feet. Now each bundle of shingles covers about 32 square feet so to figure out how many bundles we're going to need we're going to have to divide our square footage by 32 and that's going to give us about 44 bundles. That we're going to need to buy to roof this house. Now on all projects you need to add in the waist factor you're not going to use every shingle and you're going to cut some so you need to add a little bit for waist in addition to starters strip and the cap. You're going to have add a little bit for those.
