Snow breaks (also known as snow guards) are roof-mounted at regular intervals and in two or more rows near the perimeter of a roof. The idea being that as snow and ice build up against the guards, it will harden and create a dam. The ice dam will prevent the mass of snow from coming off the roof all at once in a single sheet. While all agree how snow breaks are supposed to work, how do gutter installers decide among the many different designs? It is wise to choose a product that’s face is large enough to hold the snow, anywhere from 2.25 inches high and 3 inches across. Some people also think that snow breaks are better with a flat face rather than a pointed design, thinking the pointed design is more decorative than functional and does not effectively hold back as much snow.

The height and shape of the snow breaks face determine their ability to hold back layers of ice and snow. Snow guards need to be mounted in the lowest portion of a roofing panel where the snow and ice will accumulate. The flat surface should stand at least the height of the seam, creating a connected field to hold snow and ice motionless until it can melt off safely. This will protect your family and possessions from the damage of a large deluge.

The proper spacing and number of snow guards is also important for a snow breaks system to work correctly. Manufacturers should provide tested spacing layouts based on the roof pitch, panel runs from the ridge to the eave, panel widths and profile, and the snow load for which the home is designed. Using these templates, installers can use a tape measure and easily mark out where snow guards should be mounted.

Snow guards can be attached to the roof surface either with mechanical fasteners, adhesives, or tape. The adhesive mounting method is most effective on floating-type standing seam metal roofs; because it doesn’t restrict normal thermal expansion and contraction of floating metal roof panels. They can also be easily removed without damaging the panels or seams. As a general rule, tape fasteners should only be used as a temporary solution.

Finally, you have a wide selection of materials for snow breaks. Metal guards can be found in colors to match roofing panels. However, the visual benefit of color-matching can be offset by the “sundial effect” of upright metal snow guards casting shadows on the roof. Metal guards can also grow to be brittle in cold weather, and can sometimes produce rust-causing galvanic reactions with the metal roof. Another choice of material is clear plastic, including polycarbonates that are stabilized against ultraviolet rays to prevent discoloration and cracking. The plastic does not cause galvanic reactions and does not cast shadows. However, home-owners and architects can color-match the plastic snow guards to their roofs. But color-matched guards and roof panels can fade to different shades over time if the guard is not the same material as the roof.
