There is no minimum slope. The minimum slope for asphalt shingles is 3/12. Less than that you need to use roll roofing or EDPM rubber membrane.
That's a virtually flat roof. You need to use a membrane for a pitch that shallow. Anything under 1/12 is problematic for roll roofing.
I'm afraid not. When I say membrane I mean a rubber (EDPM) membrane.
