We have a potential roofing company doing a new roof on our 3-bedroom end of terrace house. He quoted us that it would only take a 1.5 days. This seemed like a very short time to do the work and we are concerned that he may be a cowboy. He also quoted us a price of 3k and everybody else has been closer to 10k. Would anybody be able to give me a ballpark figure for a new roof? Any help would be appreciated.
