Abstract: A louver roof system having a simplified assembly and installation methods. The louver roof system is constructed with multi-functional mechanical components by means of pre-molded parts to reduce skilled installation time. Louvers of the roof system each include a louver body defining an integrally formed channel configured to direct water internally from the louver body, through the integrally formed channel of the respective louver, within a frame, and out of the louver roof system when the louvers are in a closed position. The louver body of each of the louvers includes a top surface with an uppermost portion of the top surface that defines, when in the closed position, a non-perpendicular angle relative to the vertical direction such that water is directed to the integrally formed channel of the respective louver Thus, a water drainage path is an integral part of the main structural assembly.
