If a storm has damaged your home, it’s essential to take the proper steps to ensure that your insurance claim is filed correctly. Many homeowners try to deal with their insurance company on their own, but this can be a complex and time-consuming process. It’s important to have a professional roofing contractor on your side who can help you through the process and avoid common mistakes. At ACI Roofing and Exteriors, we have a system in place that will help you get the highest possible settlement from your insurance company.
