Abstract: A combined roof and solar heat collector includes a hollow box structure open at the top and presenting to the normal street viewer, the general appearance of a mansard-type roof. A row of heat collector panels in a common plane generally facing the direction of the sun is arranged within and adjacent one side of the box-like structure. A reflector surface extends from the base of the row of panels to the upper opposite edge of the box, and a rain gutter is positioned at the lowest portion of the reflector surface.
