Use this tool to convert roof surface area to standard roofing squares (100 square feet) and 3-tab shingle bundles (3 bundles per square).
This tool is built for roofing contractors and estimators who need to instantly translate measured roof areas into precise shingle bundle counts and square totals before heading to the supplier. Reducing estimation errors saves time and profit by ensuring you order the right amount of material every time.

Q: How many shingle bundles make up one roofing square?
A: For standard 3-tab shingles, one roofing square consists of exactly 3 bundles.
Q: What is the difference between a roofing square and a standard square foot?
A: A standard square foot is a single unit of measurement, while a roofing square represents a commercial block of 100 square feet of roof surface area.
Q: What waste factor should I use for hip and valley roofs?
A: Hip and valley roofs generally require a minimum of 15% waste factor due to increased side-cutting and material discard compared to simple gable styles.
