Can the 16 ft. SM-Rib Galvanized Steel 29-Gauge Roof Panel work on a low pitch?

Per the warranty, the roof pitch minimum is 3/12.

The warranty has a 3/12 limitation but technically the panel will still work at a lower pitch. The life of the panel will be shorter the lower you go and depending on how long the panel is you could run into a situation where the side lap could leak. Simple rule is the quicker the water gets off the roof the better. If the volume of water collecting on this roof is minimal then 1-1/2:12 pitch will work but it’s pushing the limits.
