Snow guards are devices used on rooftops to help snow and ice melt completely and drift off your metal roof in small amounts, rather than all at once. Without snow guards, your roof may be susceptible to “roof avalanches." A roof avalanche is the sudden release of snow and ice all at once, which can cause damage to your gutters, lower roof area, skylights, and any other objects or people below your roof. If you live in an area prone to snowfall, especially heavy snowfall, Norsteel highly recommends installing snow guards for metal roofs. As snow accumulates, ice dams can form, snow gets heavier, and your metal roof could be prone to damage which is not covered by the manufactures warranty. For more information, please email us.
