Need to know the "ground snow load" for your area?
Ask your local building department, or call a truss manufacturer in your region. Or, as an online tool, try Jabacus.com (go to the snow load tool, and select your province and town, then use "0" as the roof pitch/slope, since you want the "ground snow load", and then use the highest number that appears on the right hand column (in pounds per square foot - PSF).
Why are snow retention systems needed?
Snow and ice can dangerously avalanche off of glossy-coated metal roofing. These hazards can be prevented with the installation of snow guards.
Once frozen, precipitation loses its grip on a metal roof and begins a down-hill slide. A row of guards placed along the eave or gutter edge of the roof is not always enough protection against these dangers.
Our approach to snow guard placement involves placing snow guards throughout the entire area of the roof to keep snow and ice from initially shifting. If you hold snow and ice in place with an effective snow guard layout, you are able to evenly distribute the load on the roof and snow guards; virtually eliminating the threat of an avalanche. An evenly distributed snow load will preserve the long-term integrity of the structure and snow guard pattern.
Use our project estimator to learn about the placement of snow guards for your project.
U.S. Army Corps of Engineers Commentary on Snow Loads
This document is used by the U.S. Army Corps of Engineers as Technical Instructions for snow loads. Our SnoJax II is found on page 26, however, contrary to the image, we suggest that multiple rows of staggered snow guards be installed throughout the roof to effectively hold snow in place.
