re: Residential roofing prices

I deal with roofing almost on a daily basis and I would go with the best architect shingle you can put. Although everyone has their own opinion, I think it looks better on most styles of residential construction as well as having less issues with leaks.
The only metal roof I would put on a house would be a standing seam system and the cost are pretty high. The issues with metal roofs are very seldom with the panels themselves but 90% with the fasteners, transitions and trim.
I get paid when metal is sold, so I'm not biased against metal, just given my opinion based on years in the business.
