A Premier Roof Waterproofing Company

Your roof is designed to withstand the force of the elements and secure your home, but that doesn’t mean it’s fully protected itself. For many roofs, an extra layer of protection can help not only withstand a shifting climate but also to protect against the risks of water damage in the home.

Count on Great Falls’ reputable roofing company, A-1 Contractors, Inc., to protect your home or commercial property against water damage in just a few easy steps.

Our Services

Most people think that shingles and tiles are all it takes to protect your home against the elements when in actuality they are only the first line of defense. Many options exist for underlayers, gutter systems, and other options that should protect your roof against future internal damage. Be it from rain, snow, or sleet, your roof can be protected, and a protected roof means a protected home. Simply call us and schedule a estimate today!

    They are amazing! My mother needed a last minute replacement on her roof for the sale of the house. Within 24 hours they had the estimate back to us and … More the job scheduled. They did everything they had to so they could squeeze us in last minute. They job was done within two days! We have had roofs replaced before and usually find nails and wood all over the yard after. I couldnt believe how clean the yard was after! They really came through for us in a critical moment. We appreciate them and their professionalism so much!
