Consumer Tips - What to Know About Snow Guards - Q&A

A snow guard is a metal or plastic device installed at intervals on the roof to prevent snow and ice from sliding off the roof in a single avalanche occurrence.

We recommend metal over plastic guards because they can withstand changing roof temperatures and will hold up against the brutal effects of the sun without discoloration, cracking or breaking.

Who should consider snow guards?

Snow guards should be considered by homeowners in parts of the country where accumulating snowfalls occur.

Does my house need snow retention?

The type of roofing you have is a main determining factor. Snow tends to slide off all roofs, but is more likely to slide off "slick" roofs like metal, glazed tile, composite and natural slate roofs. These types of roofs have smooth surfaces and don't absorb water. This means that snow and ice have no place to "grip" as it might with some other roofing products. When snow begins to melt from a warm attic underneath and the sun above, the snow blanket on top may slide off the roof all at once.

How do snow guards work?

Snow guards add friction to the roof. This allows the snow to melt slowly off the roof instead of avalanching off in one big chunk.

Where should snow guards be place on my roof?

Snow guards should be placed in specific patterns on roof areas where sliding snow might land on people or property. Decks, walkways and driveways are examples of such areas.

What snow guards should I use?

There are many different types of snow guards. The most durable are made of copper, steel or coated aluminum. You or your roofing contractor can work with a snow retention company (RMSG) to specify the best snow guards for your roof and to have a snow retention layout created for your home.

What if my roof is already installed without snow guards?

While the best time to mount snow guards is when your roof is being installed, snow guards can absolutely be retrofitted after your roofing is already in place. This type of snow guard application, when done properly, will not compromise the integrity or longevity of your existing roof.

Consult a contractor or contact Rocky Mountain Snow Guards to help determine if you need snow guards. The final decision on whether or not to install snow guards rests with you.
