Deflection Monitoring: The Key to Effective Roof Management

Anyone who owns or operates a large facility in a snow-prone area must be aware of the snowfall on their roof. But many individuals are unsure about the specifics of snow monitoring. Take a minute to learn more about our process—deflection monitoring—to see if it is right for you.

Understanding the Weight of Snow

For something that's often portrayed as fluffy clouds of winter joy, snow can wreak serious havoc on a roof. The key to understanding the weight of snow is density. However, this idea is easy to understand in principle but complex in practice. Essentially, more water packed into the snow means more weight—even if it looks the same from the outside.

A common way to measure this density is with the Snow Water Equivalent (SWE), which looks at how much of a given sample is comprised of water as opposed to pockets of trapped air. Because this ratio can change quickly, the weight of snow can vary drastically from one day to the next. This frequent change in weight is what makes deflection monitoring the most reliable way to keep your property safe.
