How should estimates for wood shingles always end?

Estimates for wood shingles should always end in quarters because this practice aligns with the typical measurement and pricing conventions used in the roofing industry. Shingles are often sold by the square, which represents a coverage area of 100 square feet. The pallet of shingles may be packaged in a way that allows for fractional quantities in quarter units, making it easier to calculate and order the required amount for a roofing project.

Using quarters allows for precise calculations that can accommodate slight variations in coverage and wastage, which are common in roofing projects due to cutting and fitting of shingles. This method of estimation helps ensure that there is enough material to complete the roofing job while also minimizing excess waste. Thus, concluding estimates in quarters is not only a standard practice but also facilitates better communication and understanding among contractors, suppliers, and clients regarding the materials needed for a roofing job.
