Our townhome in Cary NC came equipped with a patio pergola made of heavy pressure-treated wooden beams. The top of the pergola has a very modest slope, perhaps 3/4 inch per foot. If we decide to install a roof over the pergola, would the vertical seam style be viable? The reason for our choice of vertical seam roofing is that other sections of our townhome have that style installed (bronze) and our Covenants are very strict with regard to architectural details. If necessary I can supply a photo of the pergola.
Thanks,

located in upstate NY. Existing roof is 2 on 12, with 3 layers of asphalt shingle. Plan is to strip of all existing & begin a new with metal roofing. Inside the roof transitions from a flat S/R ceiling to a cathedral S/R ceiling. The latter being perhaps 8" thick at best. My plan is to insulate all avaiable areas with spray in foam, a ventsulation asphalt type underlayment & then the metal roofing.
1. Any thoughts or suggestions?
2. metal roofing type or manufacturer?
Thank you,
Pat

At that low of pitch, you would need to use a mechanically seamed standing seam but, yes, it could work.

I think it sounds like a good plan and I can suggest any of the MRA member manufacturers.

That slope, as Todd said, can be accommodated by a proper standing seam.
A picture always helps and make sure that you have a slip layer between the two and PT lumber should not contact the underside of any un-coated metal or fastener.
