Wonderlin Roofing has been incredible throughout the process. Not only were they responsive to my emails and calls, but were super understanding when it came to my not-so-flexible scheduling needs. When the weather threw a wrench in the schedule, they not only were super apologetic, but explained in detail what could be done and when. Secondly, the project was done in little time. They have a crew that is obviously proficient and expedient, and finished this roof with little fuss.
They cleaned up everything and anything related to the roof demo, and not a trace was left around the property. Not to mention the roof and gutters look fantastic - the company even got kudos from the painter who came and gave an estimate, and another from the county inspector. No joke, they have a GREAT reputation. I can't recommend Wonderlin enough. Beyond that, the office and field staff were always super friendly and helpful. Kudos to Grover and his staff. Do yourself a favor and a quote from these guys. You won't regret them coming to do the work either. Not that I WANT another roof anytime soon, but I would have them do it again in a heartbeat.

The owner and his son came and did my neighbor and my roofs. The employees and owner are helpful and very nice. They're very decent with keeping things organized and cleaned up. The work looks very well done and they were quite helpful answering all of are questions. I would say that I wish they were more clear on the timeline because it annoys are dog. Other than that, they were great.
