  • "Simpson's work has been consistently excellent. Their roof inspections and repairs have resolved many long standing problems with no call backs or leaks after service. Their work on our balcony project was efficient, complete and well done. Again, no call backs or issues after their service. I look forward to calling on Simpson when needs arise as I know their work is excellent. I called on them because of their excellent work on another project I managed, with same good results."

  • "Had 3 roofing companies come out, could never find my leaks. Has these guys out and in less than 2 days found the leaks and fixed them. Needless to say, I will be using them again and again."

  • "I have been working with Simpson Unlimited for well over 20 years and they have always been professional from beginning to end of every job. Their quality of work is always outstanding. They make ever effort to make sure the job has been completed right the first time. Prices are very competitive and are a pleasure to work with."

  • "Simpson Unlimited has been my sole roofing contractor for over 10 years at multiple commercial building properties. They are always prompt with their pricing when a job requires a pre-approval. They always do quality work and their guys always skilled. They always show their me the repairs that were made and always clean up after themselves. I have come to know most of the guys by name. I use Simpson unlimited solely because I know I can rely on them to do the job right. I trust them enough that I have them do the inspections and repairs of all my roofing."
