Do snow guards work on standing seam roofs?

Clamp-to-seam style snow guards are designed specifically for use with metal standing seam roofs, and are available in options for both vertical and horizontal seam configurations.

How are snow guards attached?

Two designs are mechanically-attached, using the process of either clamping to the seam (non-penetrating) or screwing through the roof material (penetrating). The third is chemically-attached and uses a “stick-on” method, which involves gluing individual snow guards to a roof.

Can a snow guard be installed on a metal roof?

The Snow Defender 4500 Series can be installed on a regular metal roof and the Snow Defender 6500 Series are for standing seam metal roofs. All of our snow guards are stainless steel, powder coated to match our metal roofing, but may also be custom-painted in 30 different colors.

How much weight does it take to install snow guard?

As Haddock notes, the steeper the roof, the greater the forces are that act on the snow guard assembly. “For example, a 4:12 roof that is 50 feet from eave to ridge with a 40-psf design roof snow load will exert 633 pounds per linear foot of eave on the snow guard assembly,” he explains.

What’s the difference between seam and seam snow guards?

There are standing seam snow guards that are a single unit (meaning that no additional parts are needed), and there are standing seam snow guards that require additional clamps in order to be attached. Snow guards work in conjunction with each other to form a snow retention system.

How big of a roof do you need for alpine snow guards?
