Do Snow Guards Cause Ice Dams? Breaking Down Myths

A few different types of snow or ice buildups can be problematic for structures and their roofs in colder locations during the winter, and a top example in many locations here is the ice dam. A potential question from people who use snow guards as part of their snow protection approach: Do snow guards cause ice dams?

At Supply Maverick, a division of Mid Michigan Metal Sales, we're proud to offer an extensive range of metal roof snow guards, foam closure strips, roofing screws and other products to help protect your metal roof and underlying property. Here's a simple answer to the above question, plus a breakdown of some of the myths that have sprung up in this area surrounding snow guards and ice dam formation.

No, Snow Guards Don't Cause Ice Dams

The simple answer to the question is no, snow guards do not cause ice dams. In fact, they can actually help prevent them from forming in the first place. Snow guards work by evenly distributing the weight of accumulated snow on a roof, preventing large chunks of snow or ice from sliding off and potentially causing damage to people or property below.

This even distribution also allows for more controlled melting and runoff, reducing the risk of sudden water flow that can contribute to ice dam formation.

Debunking Myths

Despite evidence pointing to the contrary, there are still a few myths floating around that suggest snow guards cause ice dams. Let's take a look at some of these myths and why they're not true.

Snow guards create a barrier that traps snow and causes it to melt faster - This is simply not true. Snow guards do not trap snow, they are designed to hold it in place until it can safely melt or be removed.
Snow guards prevent proper drainage and contribute to ice dam formation - As mentioned earlier, snow guards actually promote controlled melting and runoff, reducing the risk of sudden water flow that can cause ice dams.
Installing snow guards will increase the likelihood of an ice dam forming - Some believe that installing any additional attachments on a roof can disrupt its integrity and lead to more issues like ice dams. However, when installed properly, snow guards are designed to work with the roof's structure and will not cause any additional damage or issues.

What Actually Causes Ice Dams

Don't worry, we aren't going to leave you out in the cold here (literally and figuratively!). Here are some of the main contributing factors to ice dam formation:

Heat loss from the interior of the home - This is a major factor in ice dam formation. When heat escapes through the roof, it can cause snow on top to melt and then refreeze at the roof's edge, creating an ice dam.
Inadequate insulation and ventilation - These two factors go hand in hand with heat loss. Inadequate insulation allows for more heat to escape, while inadequate ventilation can trap warm air in the attic space.
Warm weather followed by sudden cold snaps - A rapid change in temperature can contribute to ice dams forming as snow melts quickly and then freezes again when temperatures drop suddenly.

In some cases, a combination of these factors can work together to create the perfect conditions for ice dams. However, rest assured that snow guards are not one of these contributing factors.

Importance of Proper Snow Guard Selection and Installation

One possible exception to our claim that snow guards do not cause ice dams is when they are installed incorrectly or when the wrong type of snow guard is used. In these cases, it's not necessarily the snow guard itself that is causing the issue, but rather its improper installation or unsuitable design for the specific roof and climate conditions. This highlights the importance of selecting and installing snow guards correctly to ensure their proper functioning and effectiveness in preventing ice dams.

Be sure to consult with a professional or do thorough research before selecting and installing snow guards on your metal roof. And if you have any questions or concerns, our team at Supply Maverick is always happy to help guide you in the right direction.

In conclusion, snow guards do not cause ice dams - they can actually help prevent them.
