ABSTRACT:
The present invention relates to a snow guard device for use on a sloped roof having a roof decking supported by a roof substructure. The roof decking may have a plurality of elongate corrugations transversely spaced therealong. The snow guard device includes a pair of posts anchored to longitudinal members mounted to the roof substructure and extending proud of the roof decking. The posts support a rail member, which extends transversely of the elongate corrugations. The snow guard device further includes a pair of mounting brackets, which are fastened to the rail member. The mounting brackets are oriented to extend upslope and substantially downwardly toward the roof decking. The brackets carry a plurality of snow barrier members therebetween for discouraging snow from downwardly sliding along the roof decking. The snow barrier members are positioned at a location upslope of the support means and are sized to correspond generally to the spacing between a pair of adjacent corrugations. The snow guard device may also be used on other types of sloped roof surfaces, for instance, those having standing seams.
