Nathan's re-roofed our house on time, at a good price, and cleaned up the site well. However, they did not follow Virginia building code or the shingle manufacturer's recommendations about the amount of ice barrier to install (should be from roof edge to 24" inside exterior wall line). Nathan at first disputed this, saying the code only applied to new construction (incorrect, see R907.1), and that his use of an aluminum drip edge was more important (which the shingle manufacturer disputed). To resolve the situation, he agreed to extend his standard 5 year labor warranty to 25 years, and it seemed to be an honest misunderstanding on his part. And given the infrequent snow storms in VA, it's probably not a big deal. But I would insist that they follow codes, and verify that they are.
