There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 12. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.

On the other hand a roof with a ratio of 9 12 or a roof that rises nine inches for every 12 inches covered is considered a very steep slope. Water your biggest roofing concern in texas is likely water or storm damage. Roof pitch affects the amount of material needed and the type of roofing materials that can be used. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

Pitches above 9 12 are very highly angled and are designated steep slope roofs. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

For example 2 12 means a roof that rises two inches for every 12 inches covered. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.
