To calculate the number of shingles needed for a roofing project, first determine the total area of the roof in square feet by measuring the length and width of each section and multiplying them together. Then, divide the total area by the coverage area of a bundle of shingles (usually around 33 square feet per bundle). It's advisable to add an extra 10-15% to account for waste and overlapping. Finally, round up to the nearest whole bundle to ensure you have enough shingles for the job.
