Roofing/flat roof/using steel


I need to put a new roof on top of a willow walk that will be getting a reproduction railing (house is 170 years old)now minimum pitch is 2 to 3 inches in most cases and I have been told that 1" 1/4 can be used but with a tape or sealing (mastic)(butyl)I'm putting  a lot of money in to railing so I would hate to have 3" pitch roof.But don't want a leaking roof years down
the road, and rather not have a solder seam metal roof or a EPDM rubber roof. And would like to have it done before snow falls , Is there a type a seam locking steel roof that doesn't need a pitch that can be order ? or any other advise for this project would be helpful  thanks

Thanks for your question. You would have two options for a very low pitch metal roof:

1) A mechanically seamed standing seam.

2) A flat seamed copper roof where the joints are soldered.

The first could be done by a larger commercial or metal roofing contractor. The second could be done by a sheet metal contractor.

I hope this helps.

All Best,
