Metal Roof Snow Guards Spacing

In some cases, a single row will be adequate, especially if the roof runs are short. On longer slopes, a single row at the eave rarely stops a full sheet of sliding snow. Multiple staggered rows distribute weight evenly across the roof surface and greatly reduce the force placed on the lowest row. Each spacing chart linked above shows the row count recommended for that system.

Roof pitch influences both row spacing and the recommended number of snow retention rows. Steeper roofs shed snow faster and typically require additional rows, evenly spaced up the roof to prevent snow and ice from moving. Each spacing guide includes pitch-specific recommendations based on how that system performs under load.

No. Isolated rows concentrate all the sliding force in one small area and often fail. Snow guards must be installed across the entire roof width to distribute the load evenly. We never recommend localized placement for most SnoBlox-Snojax snow guards. The only exception to this rule would be if you used the snowBreaker and spaced the snow guards in a V pattern, as shown on the SnowBreaker Isolated Spacing Chart.

No. You must never puncture a Standing seam metal roof. Doing so may damage the panel and void warranties. Use adhesive-mounted guards, seam-mounted SnoCleat RC/RCT, or clamp-on SnoBar® and ColorBar rails instead. Each spacing page above lists the correct attachment method.

System selection depends on roof type: standing seam, exposed-fastener, PBR/R-panel, or 2.67 corrugated. Each image block above links to a dedicated spacing page that explains which snow guards are compatible with your profile and how to space them.

Projects with heavier snow loads require manufacturer layouts to ensure proper load distribution. Contact SnoBlox-Snojax for a custom SnoBar® or ColorBar layout before ordering materials.

Yes. Adhesive systems such as SB-190 must cure fully before the roof if subject receiving a snow load. Cure time varies by temperature and humidity. The adhesive spacing and installation guide linked above provides detailed preparation and cure information.

If you space rows of snow guards too far apart, the system can't retain snow and ice as it should. Push it past the limits, and guards can bend or even pop off under the weight. Ensure proper spacing, as indicated in our charts, to evenly distribute the snow load across the roof.
