Can you please advise on any building code that sets a minimum for the pitch of a roof?
When obtaining an estimate for patio covering, I was told that a shingled roof wouldn't work the way I wanted due to minimum roof pitch code.
The answer for "what is Frisco's code" would suffice, but if you can briefly summarize any reasoning for a minimum slope, I'd love to understand the logic behind it.

Section R905.1 of the International Residential Code specifies the minimum roof slopes based on the type of roof covering material. Roofing material manufacturers also provide minimum slope recommendations. Asphalt shingles require a minimum slope of 2 inches in twelve inches. To utilize a lower slope you would need to choose a different roof covering material such as a standing-seam metal roof or a built up roof covering.
