Life is too short to have to do any job twice. I've seen it all too many times where a business person trusts another business without having ever checked their references or work. In the complicated specification world of Commercial Roofing this is even more important. A new roof can easily cost as much as a new car or even a new house. When dealing with that amount of money, connecting to the wrong flat roofing contractor, and or buying the wrong roof can be an expensive economic disaster.
