Prevent Snow Buildup on Your Commercial Roof with Mint Roofing’s Commercial Roof Snow Removal Services.
It’s that time of year again when we get to enjoy the beauty of winter and all the joys it brings. Unfortunately, commercial flat roofs in Minnesota are not immune to snow buildup during this season. This can cause leaks and other costly problems for commercial building owners and managers alike. Fortunately, there is a solution – commercial roof snow removal services from Mint Roofing.
Do I need to clear the snow from my commercial roof?
The answer to this question depends on the type of roof, the weight of the snow, and the load capacity of your roof. Commercial property owners should generally schedule snow removal any time it gets to be more than two feet deep.
What should I watch out for?
If you look up at your roof and see ice dams in the downspouts or snowdrifts over the edge of the roof, you’ll need to take immediate action. You may also hear cracking noises inside your building if your roof has too much weight on it.
If you witness any of these signs, you should have an expert check it out as soon as possible to prevent damage to either your roof structure or the interior contents of your building.
The weight of accumulated snow can cause a roof to collapse, causing damage to the contents of the building and serious injury or death to its occupants.
How much does the snow on my roof weigh?
The weight of snow varies significantly based on the moisture content – generally, the colder the temperature during the snowfall, the lower the weight. Snow’s water content can range from 5% to 32%. Snow falling on a 10° day has much less moisture content than snow falling at or near the freezing point. Snowfall on warmer days also tends to have higher accumulation.
One inch of fresh snow weighs between .25 and 1.65 pounds per square inch, meaning a 6″ heavy, wet snowfall could weigh 9.9 pounds per square foot. That doesn’t sound like much, but it means that a commercial roof with an area of just 1,000 square feet could potentially have more than 10,000 pounds of snow weight – just from a single 6″ snowfall.
Of course, we all know that it doesn’t snow just once each winter in Minnesota. Snow accumulates. And as snow accumulates, it compresses and increases in density, increasing the weight on your roof.
Combined with freezing and thawing weather cycles (and even winter rain), the bottom layer of accumulated snow eventually turns to ice. Ice weighs as much as five times the weight of even heavy fallen snow. When your 6″ of snow turns to ice, and it snows just six more inches, your 1,000 square foot roof could now be supporting as much as 60,000 pounds! That’s like parking 20 Honda Civics on a 20′ x 50′ roof!
In addition to the increased weight, this layer of ice can prevent your roof from draining as designed. The presence of ice dams means no water is leaving the roof and that the scuppers are blocked as well.
Under intense pressure from the weight pushing down on it, melting water will try to escape wherever it can. With nowhere to go, the hydroponic pressure finds weaknesses in your roof structure, and the water may force its way inside your building.
Drifting snow makes matters even worse.
As the wind blows the snow around on your roof, it will invariably cause snow to drift in certain areas. Drifting causes snow weight to be concentrated in a smaller area of your roof, increasing the load per square foot. Increased load means a greater risk for roof damage – from leaks to roof collapse.
Should I try to clear snow on my commercial roof?
If you’re a commercial building owner or manager who is trying to decide whether it’s safe and effective to clear snow off your commercial flat roof on your own. We always advise our clients against attempting to do this on their own.
Damage from snow improper snow removal can cause costly repairs to your roof. Shoveling or blowing snow from your commercial roof snow risks damaging gutters, soffits, and even the roof surface itself. The type of roof you have determines the safest method to use.
The other issue faced by facility managers is that of roof access. The weight of even a moderate snowfall can make it impossible to open access hatches and doors. When this happens, the only way to access your roof is from the outside, requiring a ladder or more elaborate lift equipment.
If your roof is large, you’re going to have a lot of snow to move. Removing snow from large commercial flat roofs takes a lot of time and effort. And depending on your building’s location, you need to know where the snow should go and how to get it there safely. Great care needs to be taken to prevent snow from landing on cars, property, or people below.
It’s just not worth the risk to try to clear snow from your roof yourself.
