A roof mount apparatus for mounting on a roof surface includes a first solar panel having a first frame secured to the roof surface, a second solar panel having a second frame secured to the roof surface, the second solar panel spaced from the first solar panel and defining a slot between the first and second frames, and a snow fence secured to the first and second frames. The snow fence includes a bracket positioned adjacent to a top of the first and second frames, the bracket protruding from the first and second frames to inhibit sliding of snow along at least one of the first and second solar panels, and a coupling device including an elongated portion positioned in the slot and extending substantially perpendicular to the roof surface and a wide portion positioned within a channel to couple the bracket to the first and second frames.
