US Patent 7174677 Snow guard for shingled roofs

A snow guard for a shingled roof in which the flat attachment strap positionable between layers of shingles has mounted thereon a detachable mounting bracket that projects upwardly from the attachment strap. The body portion of the mounting bracket has a wedge-shaped receptacle on the top surface to mount devices such as a snow guard attachment, which can be locked into place on the mounting bracket by a threaded fastener that passes through the mounting bracket into the base of the snow guard attachment. The snow guard attachment can be easily replaced with aesthetically different snow guard members or a snow fence that spans across several aligned mounting brackets.
