Stop roof snow slides with Roof Snow Guards.

Installation Instructions

Snow and ice can dangerously avalanche from metal roofs because it begins to melt and lose its grip with the slick metal surface. Snow guards are installed throughout the entire roof area, using a spacing diagram, to help prevent dangerous avalanches. Snow and ice that is held in place with snow guards is safer and is also more evenly distributed across the structure and snow guard installation.

Important Considerations:

  • Installing snow guards can be dangerous if your are inexperienced or not qualified to be on the roof.  Please consult with or hire a local roofing professional if you are unsure about being on the roof.
  • The SureBond SB-190 adhesive require a full month of warm weather to cure correctly.  It is best to install glue down snow guards in late spring or early summer.
  • Snow guards attached with screws require adequate material to screw into.  Metal roofing material alone is not enough.  Be sure to screw into wood purlins, metal purlins or heavy plywood decking.
  • Both screw down and glue down methods will cause adhesive or silicone to squeeze out around the perimeter of the guard.  Be sure to wipe around the entire perimeter to close any gaps. It is important to prevent water from seeping under the guard, where it will freeze and expand, causing the guard to eventually fall off.


How To Install Snow Guards:

  • Begin by referring to the spacing diagram we provided and determining the number of rows required.
  • Mark the first row using a string running the length of the roof.  Snow guards are installed in a staggered pattern, instead of straight rows, to better distributed the load on that row.  Snow guards are also installed centered on the panel. Proceed to mark each spot with a pencil.
  • Wear protective work gloves and clean the area around each mark with warm soapy water or isopropyl alcohol. The surface should be clean of any grease or dust.
  • If using the glue down method (adhesive attachment), apply clear SureBond SB-190 snow guard adhesive to the bottom of the first snow guard. Be sure to evenly cover the entire bottom of the guard with the adhesive. Firmly press the snow guard onto the roof. Repeat for each snow guard in the row.
  • If using the screw down method (mechanical attachment), apply high grade outdoor silicone to the bottom of the first snow guard. Be sure to evenly cover the entire bottom of the guard with the adhesive. Firmly press the snow guard onto the roof. Hold the guard in place and using the correct screws and a powered drill, proceed to screw the guard in place.  Repeat for each snow guard in the row.
  • Repeat the process for each row up the roof run, according to the snow guard spacing diagram.
