  • LOAD SENSITIVE SNOW BARRIER DEVICE
    Publication number: 20100192479
    Abstract: A snow-retaining device comprises a detachable upper member attached to a base anchor. The base anchor is adapted to be coupled to a roof. The upper member prevents snow from sliding off the roof during regular snow conditions. In order to prevent catastrophic damage to the roof, if a snow load on the roof exceeds a maximum threshold, the upper member detaches from the base anchor to allow some or all of the snow to slide off the roof. The device optionally integrates a snow melting device.
