In roofing, what represents a 'bundle'?

The correct choice represents a 'bundle' as a unit quantity of shingles, which is a standard measurement in roofing terminology. Typically, a bundle contains a specific number of shingles, usually around 20 to 30, depending on the type and brand. This unit of measure helps contractors and suppliers communicate more effectively about quantities needed for roofing projects.

Understanding this concept is essential, as roofing projects often require estimating the number of bundles required based on the area to be covered, the style of roofing, and the local building codes. Having a clear grasp of what a 'bundle' refers to aids in accurate calculations for material costs and inventory management in roofing applications.
