How far apart should snow guards be placed?

In general, snow guards should be placed 1 every 40 inches over entire roof or in 2 groups of 3 staggered rows on 30 inch centers with 1 group at the eave and 1 group midway on roof slope. On long slopes, multiple groups with 6 ft. space separation maximum.

Do I need snow guards on my metal roof?

Do I Need Snow Guards? If you live in an area prone to snowfall, especially heavy snowfall, Bridger Steel 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 cave-ins.

How do you divert snow on a metal roof?

Prevent Snow From Sliding Off a Metal Roof The best way to stop snow from sliding off your metal roof is to install snow guards or a snow fence on your existing roof. Snow diverters are also important to stop sliding snow from damaging roof fixtures and causing leaks.

How many snow guards do you need for a metal roof?

Use: 1 snow guard per valley every 15 feet of roof. Snow load: Up to 45 PSF ground snow load. Starting at 1 foot from the bottom edge, place a snow guard in the center of each valley, in a staggered pattern, across the entire roof area.

What to put on metal roof so snow will slide off?

In order to prevent snow and ice from creating a small avalanche, many homeowners opt to install snow guards on their steel roofs. Snow guards are designed to keep large amounts of snow and ice from sliding off a metal roof all at once.

How do I keep snow and ice off my metal roof?

Snow guards are one way to prevent a massive avalanche of snow from falling off your roof. But in most areas of the Pacific Northwest, these are often thought of as overkill. They allow small amounts of snow to slide off bit by bit or hold it in place until it melts.

At what pitch does snow slide off a metal roof?

Anything over a 6:12 pitch tends to make massive amounts of snow slide off the roof without warning. Anything less than 1:12 pitch is a huge mistake in snow-prone climates. Standing seam metal roofs— which allow snow to slide more easily— might do better with a 2:12 or 3:12 pitch.
