When calculating total square footage for roofing, what factor should be included?

When calculating total square footage for roofing, it is essential to include the pitch and overhang because these factors significantly affect the actual surface area of the roof. The pitch refers to the slope of the roof, which determines how much additional area is needed for the roofing material to cover the angled surface. A steeper pitch increases the square footage, as the surface area is larger compared to a flat or lower-pitched roof.

The overhang, which is the part of the roof that extends beyond the walls of the building, also adds to the total area that needs to be covered. This part is crucial for drainage and protection from weather elements. By considering both pitch and overhang in the calculations, you ensure that the estimate for roofing materials is accurate, preventing shortages or excess materials that could lead to additional costs.

In summary, including both the pitch and overhang allows for a comprehensive calculation of roofing area, which is necessary for effective material planning and ensures proper installation and performance of the roofing system.
