Sheathing under a metal roof on a carport?
Hi,
new to the forum but its already helped me a lot in projects around the house. Thanks!
I have a carport "frame" built from 1.5" steel square tubing. Its about 8', 12' wide, and 16' long. I'd like to put a solid roof on it. Its basically flat, with enough of a slope so water drains. I'm thinking I will use corrugated metal roof panels.
It seems to me like it will be okay to just attach the panels directly to the frame (there's cross members to support them). I don't really need sheathing underneath it, do I?
Thanks,
Jeff

As long as you can screw the steel down to the cross members, and the cross members are every 3 ft or so, you'll be fine. No sheathing is needed.

Great, I was hoping someone would say that. After some thought, I've got a small workshop that needs a new roof as well. It has a nearly flat roof so I am reluctant to just use roofing felt and shingles - eveything I have read says that you need a steep pitch with that system.
So I guess that leaves me with a rolled roof type setup - felt paper/roofing tar/rolled roofing or elastomeric coating, OR
Think I could just use a corrugated metal roof on top of the rafters? Or maybe use some 1x4's perpendicular to the rafters for greater support? Living in Tucson, I don't think condensation will be a problem, and its not a living area or anything.
Thanks,
