What is the general quantity of bundles typically utilized in shingled roofing application?

The typical quantity of bundles used in shingled roofing applications is approximately four bundles per square. A roofing "square" is a unit of measure that covers an area of 100 square feet. Most standard three-tab asphalt shingles require about four bundles to cover one square, taking into account the overlap and waste that occurs during installation. This standardization allows contractors to estimate material needs accurately when planning a roofing project.

Understanding this quantity helps contractors calculate the total number of bundles required based on the total square footage of the roof. While individual roofing shingles may vary somewhat in coverage, four bundles per square is a widely accepted industry standard, reflecting best practices in estimation and material procurement.
