The roof pitch factor is a multiplier used to adjust the square footage of a building's footprint to account for the slope of the roof. Steeper roofs have a higher factor because they require more materials, like shingles and underlayment. This calculation is essential for accurate material estimates and cost planning in roofing projects.
