Button-
Do I need snow retention on my metal roof?
Metal roofing can allow accumulated snow to release quickly. Whether snow retention is appropriate depends on your roof design, snow loads, and what is located below the roofline.
-
What's the difference between ColorGard and DualGard?
Both are S-5! snow retention solutions, but they use different system designs. GSMRF can help you determine which option makes sense for your project.
-
How much snow retention does my roof need?
System requirements vary based on the roof and project conditions. S-5! provides a load calculator, and our team can help point you toward the appropriate system and components.
-
Can I add snow retention to an existing metal roof?
Depending on the roofing system and conditions, snow retention may be added to an existing metal roof. Talk with our team about your roof profile and project.
-
Do you carry the clamps and accessories I need?
Yes. GSMRF stocks snow retention and related metal roofing accessories from our Gunnison shop.
-
Is taller snow fence better?
Extra height increases tipping force through leverage. Taller bars usually mean failing snow retention systems.
