Normal roof slope for typical installation. A gable roof is a traditional triangle shaped roof that can range from a medium pitch to sharp angled roofs.

Normal shingle installation is allowed for all roofs with a pitch of 4 12 and above. To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope. It is uncommon to find a roof below 15 but for those very low pitch applications there are interlocking clay pantiles available suitable for use down to 12 5.
