A roof attachment system and methods of using same during the installation, maintenance, or repair of a roof on a commercial or residential building structure. The roof attachment system and the related methods of using and implementing the system include, among other things, an anchor or internal support assembly, and a hook or securement assembly. The roof attachment system enables the installer to utilize at least one internal support assembly, or at least one internal support assembly and the securement assembly to install the roof, depending upon the installation stage of the roof. Upon completion of the installation process, the roof includes multiple concealed internal support assemblies that provide multiple anchor points that are spaced an appreciable distance apart along the ridgeline of the roof. When the roof requires maintenance or repair, the securement assembly can be removably coupled to a specific internal support assembly to facilitate the maintenance or repair by a technician while also reducing the chances that the technician experiences a fall from the roof.
