Everything You Need to Know About Snow Breaks and Metal Roofs

In Montana we often face massive bouts of snowfall, sometimes as much as two feet in a single day! Snow can accumulate on your roof very quickly and, in the case of some metal roofs, the snow can fall off of the roof unexpectedly. These “roof avalanches” happen because metal roofs—unlike shingle roofs—are very smooth, so they do not provide any resistance to keep snow from sliding off abruptly. In the case of a roof avalanche, the heavy and rapid snowfall can cause damage to property and hurt people. If you have a metal roof in a wintery landscape like Montana, having snow breaks can save you a lot of hassle and money later on. 

What is a Snow Break?

A snow break (sometimes called a snow stop or a snow guard) is a device installed on a roof to help snow and ice melt off slowly and in an organized way. They are often attached in a pattern, usually to the flat part of a metal roof panel, or clamped to the seam. Snow breaks increase friction between the metal roof and the snow, which helps them retain snowpack. This way the snow will evacuate in a predictable manner, not a sudden, sometimes deadly, roof avalanche. 

A roof snow break comes in two different categories: small profile (which is less than four square inches) and large profile (which is more than 4 square inches). Within these two categories, there are different styles of snow breaks you can choose from, including bar, fence, pad, and rail styles. Depending on how you want the snow breaks attached to your roof or the aesthetic you want, you may select either kind of profile or style for your home. If you need a hand choosing the best profile and style for your home/business’s metal roof, you can always reach out to one of our professionals for expert advice here

Top Benefits of Snow Breaks

Protection for Building Occupants and Pedestrians

Snow breaks can help protect your home/business’s occupants and the surrounding people who walk below your roof. Roof avalanches can be deadly, so it’s best to put safety first and install snow breaks. Protect the “danger zones” around your home/business, such as the entrance/exit doors or areas where pedestrians walk or vehicles load.

Protection for Surrounding Property

After steady accumulation, snow falling off the roof can be so heavy that it damages the surrounding property. Whether it’s a vehicle, patio furniture, or equipment, a roof avalanche can destroy whatever it lands on. Snow breaks can help you avoid this damage by diverting the snowfall from your property and breaking it up into manageable, lighter pieces of snowfall.

Reduce Roof Maintenance Costs

Did you know snow breaks can actually help you save money? Heavy snowfall can sometimes cause needless wear and tear on a metal roof or damage they were never designed to handle. This can lead to unplanned roof maintenance and unplanned bills. A properly installed snow guard system can help reduce your future maintenance costs.

How to Install Snow Breaks on Metal Roof Panels

A snow break is attached to a metal roof’s surface through adhering with a liquid adhesive, tape, mechanically with screws, or with clamps. Depending on the style of snow break you get, you will want to refer to the instructions and installation guides provided by the manufacturer. 

When installing snow breaks, remember to position them on the lower half of the roof. You will typically place them in a single line or multiple rows, depending on the type of snow break you get. One thing to keep in mind when installing snow breaks is ensuring the overall spacing of snow breaks on the roof is done properly. If the breaks are not spaced equally or in a pattern to equally distribute the snow, the ice and snow may shift suddenly and create a snow avalanche. 

Pro tip: It’s a good idea to get snow breaks for metal roofs installed before the snowy season hits. Many people either manually install or schedule installations in the late spring or summer so they can be prepared for the fall and winter seasons.
