Best Residential Plumbing Systems in Phoenix AZ

Diversified Roofing is the company who installed the roof on my new build house in Dec.2013. It appears they installed the O'hagin vents incorrectly, and now have water stains on my ceiling. Disappointed, but not surprised after reading reviews. They wouldn't even come out to look without charging me $95, which I said forget it. Of course several other roofing companies were happy to come out, free of charge to look to see how they can fix Diversifieds mistakes. Zero stars for workmanship and customer service.
