The roof pitch or slope refers to the rise or fall of a roof over 12 inches. Roof slope is typically expressed numerically, such as 1:12 or 1/12, meaning the roofing plane increases 1 inch above the eave height for each 12 inches the run travels toward the ridge.

Metal roofing is well-known for its outstanding performance against mother nature. From hailstorms to hurricanes, metal roofing performs better than other material options like membrane roofing and shingles. With that said, like with any other product, problems can occur.

While installation errors lead to most issues, panel side laps, incorrect panel profile selection, and fastener locations can be problematic for exposed fastener panel installations on lower roof slopes.
