CA 2418587

A metal snow guard is provided with 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 preferred soldering material comprises an interior layer of solder and an outer layer of flux. In one form, the soldering material is in the form of spaced spots or projections providing a rough surface on the underside of the snow guard with the projections melting and spreading laterally into uneven surfaces where the roof or the base of the snow guard is not flat. 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 preferred snow guards are formed of sheet metal of relatively few pieces and which are folded and joined together in an inexpensive manner. Preferably, the projections of soldering material are formed by forcing a paste of solder and flux through spaced holes in a plate or screen onto the base and then applying heat to melt the past and form a crust of flux on the outside of the projections which are mainly then comprised of solder. The outer crust layer of flux should protect the inner solder from oxidizing.
