Metal roofing is well known for its durability, longevity, and excellent performance in Canadian winters. One question we hear frequently from homeowners is:
“Will snow slide off my metal roof?”
The short answer is yes, metal roofs shed snow more easily than asphalt shingles. The good news is that this is a benefit when managed properly. Let’s explore why this happens, whether it’s a concern, and how homeowners can stay safe during winter.
Why Snow Slides Off Metal Roofs
Metal roofing has a smooth, non-porous surface. Unlike asphalt shingles, which grip snow and ice, metal allows snow to release naturally as temperatures fluctuate.
This helps:
- Prevent heavy snow buildup
- Reduce ice dam formation
- Protect the roof structure from excessive weight
In many cases, shedding snow is a sign that your roof is working exactly as it should.
Is Sliding Snow a Safety Concern?
While snow shedding is beneficial, it can become a concern in certain situations, such as:
- Roofs above entryways or walkways
- Areas above decks, patios, or driveways
- Steeper roof slopes
- Homes with high snowfall accumulation
When snow releases all at once, it can fall in large sheets, potentially causing injury or property damage below.
How Snow Guards Help Control Snow Shedding
Snow guards are designed to manage how snow leaves the roof. They hold snow in place so it melts gradually instead of sliding off in one large mass.
Benefits of snow guards include:
- Improved safety around entrances and walkways
- Protection for eavestroughs and landscaping
- Reduced risk of damage to vehicles or outdoor features
- Peace of mind during freeze-thaw cycles
Snow guards are especially recommended for Canadian homes where winter conditions can change quickly.
Do All Metal Roofs Need Snow Guards?
Not every metal roof requires snow guards. Whether they are needed depends on:
- Roof pitch and design
- Snowfall amounts in your area
- Where people or property are located below the roof
- The type of metal roofing system installed
A professional assessment can determine whether snow guards are necessary and where they should be placed for maximum effectiveness.
Will Snow Guards Damage the Roof?
When properly selected and professionally installed, snow guards do not damage metal roofing systems. It is essential that the snow guard style is specifically matched to the type of metal roof profile or shingle being used to ensure proper performance and load distribution.
Choosing the correct snow guard system and installation method helps maintain the roof’s long-term performance, appearance, and warranty coverage, which is why professional assessment and installation are strongly recommended.
