I think Northern Virginia Roofing does a pretty good job of helping out and doing the right thing. I know of them because of my job in the construction business, and I had them out recently to do a complete roof replacement. There were some things they didn't finish at first, such as flashing on the side, and some gutter work, and it took them a bit to get out and get the job done. But other than that, everything was good. The workers do a pretty good job, and they have a quality control person, which I think goes a long way. I like them overall and will continue using them.
