The professional installers at GMCI not only have the knowledge, but we also have all the right tools to fix any sort of repair. To get an experienced installer out to your property, we charge $100 to diagnose your roof repair. This will include the service fee, along with one hour worth of work. The $100 does not include any material, so based on the diagnosis, material and labor costs will be presented. We are confident you will be satisfied with the professionalism and crafsmanship GMCI offers.
