Looking for a Real Metal Roof Pro in Raleigh, NC

Guys, I'm contracting a large remodel project which includes a 16*28 foot screened porch addition. The design requires a near flat roof (approx. 1/4" = 3/8" fall per foot). I'm looking for a recommendation on a roofer in the Raleigh, NC area that is a real pro with custom metal roofing, and knows exactly how to fabricate a water tight flat roof.

Thanks!

Hears just a few pictures of what you need. Flat lock copper with soldered joints.

Wow, that's impressive work. Anyone do this kind of work in the North Carolina area?
