    If anyone needs a new roof I highly recommend A-1 Contractors Inc in Great Falls.
    They started one afternoon and had it finished the following day. The
    … More group was extremely friendly and efficient. I was impressed at how clean my yard stayed during the entire process. When they left, there was no sign that they were here except for a fantastic new roof and their sign in our yard.

    My family and I were cleaning up an old building that was in desperate need of a new roof before any other work could take place. A friend of the family … More recommended A-1 Contactors. They said they had heard many good things. We couldn't agree more! They were quick to answer us about an estimate (which was very reasonable) and when they would be able to start. They even squeezed us in sooner than they said which, in construction, is always a happy surprise! Their employees were very polite and informative when I had questions. It was nice to have someone take the time to explain why they needed to do what they were doing. It all went very quickly and they cleaned up everyday. Our roof looks amazing and it is the best feeling to hear rain go down the gutter now instead of in the building!! A-1 Contractors is a great business and I would feel very comfortable recommending them to anyone. We are grateful for your help with our diamond in the rough!
