If you live in an area where snow is not only a constant winter companion, but also one that doesn’t leave, then you know by springtime, it can turn into mountains in parking lots and create canyons out of roads. What many homeowners fail to remember is that this kind of pile-up also puts a lot of weight on a roof. While home construction can be rugged if done right, your roof has a limit when it comes to extra weight, and the weight of snow can be deceptive. As more of it piles up, the stuff on the bottom is compressed, becoming thinner without losing any weight. That means a foot of snow can have much more than double the weight you would see from six inches of snow if it comes slowly and compresses old layers of precipitation instead of falling in a single spree.
How To Manage Snowy Rooftops
Any home that has a high insulation factor in the upper levels and roof will wind up with a snow pileup, because if heat doesn’t escape the house to melt the snow it won’t just melt off on its own until the thaw. To know whether it’s time to intervene on your roof, you need a system that can handle measurement of roof snow load levels and warn you if they reach a dangerously high point. From there, it’s a matter of deciding how to clear the weight. You’ll want to work with a professional partner who can safely remove the load without worrying about the slippery winter weather.
Prevent Water Damage
Keeping snow buildup minimized is about more than just the weight on the roof. It’s true, cracking roof boards or even having a cave-in would be catastrophic. The more common and just as costly consequence, though, is the slow water damage over time from the lower levels compacting into ice that partially melts and refreezes as the snow above insulates it. This allows for ice and eventually water that forces its way under shingles or even vent caps. This damage is quite common and totally preventable.
