ABSTRACT:
A method of making a metal snow guard is disclosed. The snow guard has a solid layer of soldering material on its base to be heated and melted with application of heat to the upper side of the snow guard to solder the base to an underlying metal roof. The soldering material may be applied as spaced spots or projections providing a rough surface on the underside of the snow guard. The amount of solder and/or flux in the solid layer is limited so that the solder and/or flux does not flow outwardly from the snow guard and run down the metal roof thereby damaging or marring the metal roof surface. The snow guards may be formed of a few pieces of sheet metal. The projections of soldering material may be formed by forcing a paste of solder and flux through spaced holes in a plate or screen onto the base.
