Metal roof for lean to shed?

[shedpaul]

Leafing through the lean to shed plans and saw that a metal roof was recommended as the pitch is very low. The Home Depot selection of metal roofs indicate they want a minimum of 2 1/2 pitch which I think is almost 12degrees. The lean to plans have a 7deg sloped roof. Do I need to find a specific metal roof type for this low pitch?

Thank you,
Paul

Just make your screws are water tight. Either by using screws with rubber washers, or tar on the screw heads. Also use as few as possible. More pitch is better but I have built many sheds and porches with a low slope that don't leak.
