2018 update:
We had a flat roof leak during the ice storm earlier this year that leaked into my son's bedroom. Ryan hadn't replaced the flat portion of our roof when he did our roof in 2015. At the time he said that the condition of the flat roof was fine. Ryan stopped by after the ice storm this year to have a look. He said that the issue wouldn't happen again on the flat roof until another ice storm since he said it was due to ice buildup. He said that we could address it before the next winter.
Then with some of the 2018 torrential summer rain we had, the flat roof leaked into my son's bedroom again. I texted Ryan about the flat roof leak. It took Ryan about a week to get back to me. He sent a one line message saying that he was sorry, he wouldn't be able to fix the flat roof.
I recently had the flat roof inspected by other roofing companies and they found numerous big issues with it that Ryan had surprisingly never pointed out to me the numerous times that he inspected our flat roof. In addition, the other roofing companies found a couple of installation issues from Ryan's work that I plan to pay them to correct.
I would have appreciated it if Ryan would have not left me hanging about the flat roof, so that my attic wouldn't be unnecessarily ruined by rain. I was not impressed with his inability to proactively follow up to get to the root cause of flat roof issues. I can't confidently say that Ryan stands by his clients, and I definitely wouldn't recommend him for any flat roof work.
2016 update:
Fast forward to September 2016...and there was a 6 inch diameter water stain in one of our small bedrooms. I called Ryan and he came out quickly to inspect the roof, take photos, and show me what happened. It turns out some pesky raccoons had decided to damage one part of our roof - I'm assuming they were trying to get into the attic. Ryan quickly fixed the issue for a very reasonable fee.
2015:
Ryan did our roof in July 2015. He came in at a reasonable price and did a great job on our house. It looks amazing. He communicated well, and got back quickly. He took the time to thoroughly explain things. He removed the old shingles, fixed a couple of pieces of wood under the roof, and significantly improved the curb appeal by removing an unused roof vent located on the roof facing the street.
Ryan did all of this for us in a timely manner, and cleaned up the worksite well.
