How to measure a roof to determine the number of bundles of shingles needed

You need to find the square footage of your roof in order to accurately determine the amount of shingle bundles you'll need. Here are four easy steps you can follow:

1. Measure the length and width of each portion of your roof
2. Multiple the length and width of each side
3. Add the amount from each section together to get the total square footage
4. Divide the total square footage of the roof by thirty-two to find the number of bundles or shingles that are needed
