To figure out how many shingles or tiles you need for a roof, a roof area calculator is essential. Enter your roof's pitch and dimensions, and it crunches the numbers for the total square footage. This saves you from climbing up with a tape measure and doing complex math on a slope. Just remember to account for overhangs and waste—usually around 10% extra—to avoid a shortage mid-project.
