In terms of roof slope, what is the definition of "slope"?

The definition of "slope" in terms of roofing refers to the vertical rise compared to the horizontal run. This ratio is crucial for understanding how steep a roof is. The slope affects water runoff and can influence the structural integrity and longevity of the roofing materials.

The measurement is typically expressed as a ratio, which indicates how much the roof rises vertically over a certain distance horizontally. For instance, a slope of 4:12 means that for every 12 inches of horizontal distance, the roof rises 4 inches vertically. This ratio helps builders and inspectors understand drainage patterns and potential snow load considerations, making it an essential factor in roofing design and maintenance.
