ABSTRACT:
By incorporating an elongated, generally upstanding, aperture-bearing tube member in the top of a roof drain cover or debris guard, with said elongated pipe extending into the interior of the roof drain assembly, a unique roof drain system is achieved which virtually eliminates clogging of the drain by debris, water, ice or snow buildup. By incorporating the upstanding, elongated pipe member, a safety overflow system is provided which establishes a clog-free flow path for carrying away any water buildup that might otherwise occur from clogged drain covers. Preferably, a generally cylindrically-shaped, elongated tube member is employed which is adjustably mounted to the roof drain cover or debris guard for telescopic, axial adjustable movement relative thereto. In this way, the length of the tube member exposed above the drain cover is adjustable, in order to accommodate alternate roof constructions and drainage problems.
