This is a loaded question. some metal roofing systems claim to be capable of shedding water at only 1/2" per foot slope. It is also true that there are some membrane type options (cold process) that will work at very low pitches. Having said that, as a roofer who has installed every single one of these different methods, including hot mop, I would lean ...
Where is the water going? Off the highest point. Use manual nut driver and long enough screws. The valleys of the panels are the most likely source of leaks! Metal roofs with screws need far less fasteners than one would think. The roof will expand and contract better with less fasteners-No it will not blow off any quicker than a single screw tile roof ...
We really need to see a photo of the house to make specific suggestions. Here's one that would lead to a more modern look. The idea is to frame out a 'level' frame with the roof inside it. From the ground, it appears to be a horizontal awning and you can clad it any way you see fit. Here's a crude ascii sketch showing a side-view cutaway: ...
One of my business partners is a roofing and gutter company in Eastern NC. It varies, but code requires a membrane roof on a .25/12 pitch and I have seen a number of houses around here with a small covered entry like what you describe with a EPDM (black rubber membrane) roof. Typically it will be trimmed with a metal edge band and doesn't look bad at all. ...
Best way to improve looks is to rebuild it so that the roof has a real slope to match other parts of the house 4/12, 5/12 6/12 etc. To get that slope tie the rafters up higher on the side wall of the upper level or merge into the upper roof. Then roof this with roofing to match the rest of the house. Nearly flat roofs with corrugated plastic / fiber glass ...
You are absolutely right. The kind of roof you describe does not need to be vented, and in fact cannot be vented without compromising all the polyiso insulation you had added (that was a good idea!). The roofers have damaged your insulation layer and put your roof at risk. Call them back and make them fix it. If they won't, call the contracting board.
This would be a situation where you'll have to use gutter straps (usually in T or K style): Image credit to acehardware.com They install on the roof decking - make sure to follow the manufacturer's instructions, as you'll be penetrating the singles. Image credit to www.heritagehillweb.org
Usually this is prepared at the time of roof install, but with care, may be retrofitted, using these brackets.
