    Had a recent storm?
    Your roof may be damaged
    even if it looks fine.

    Hail and wind damage is often invisible from the ground. Insurance covers most storm damage repairs at little to no out-of-pocket cost, but waiting too long can void your claim window.

    What Our Customers Say

    200+ Five-Star Reviews Across Google, GAF, and BBB

    "ACI acted quickly and efficiently in taking care of our roof claim. Shawn came over right away and inspected our roof. ACI worked well with our insurance company, and their installation crews worked tirelessly to finish the tear off and replacement in one day. The gutter crew followed the roofers and then the window wrap crew finished us up. I would gladly recommend ACI for roofing and exterior needs. They are First Class Professionals."

    "Shawn and his crew were great. They managed working with the insurance company. We had renters coming in and they got it done in time. It looks great. Thanks ACI!"

    "We had a great experience with ACI. Shawn was quick with providing an estimate and explained everything to us up front. Quality of work was excellent and they didn't try to up-sell us on anything we didn't need. You won't find a better 'bang for your buck' than ACI. I have a new patio that will need a roof soon and there is no doubt in my mind who I will call for the job."
