A composite reinforcement for a vehicle roof opening that provides several advantages over the prior art metal ring design. The reinforcement is a composite bonded to the roof, can be polyurethane, and may include fiberglass, such as long fiber injection (LFI) or glass fiber mat. A honeycomb core can also be disposed within the polyurethane made from cardboard or aluminum. Steel inserts can also be formed within the composite to provide attachment points for a variety of functions, such as sunroof module, structural brackets, and locating assemblies. The steel inserts can have external threads to allow composite material to physically capture the insert during formation of the reinforcement. This roof assembly can be mounted to the vehicle in an optimized manner for ease of assembly, color matching, and to provide structure to support a mounted sunroof assembly.
