Are you concerned about the snow load on your building? Well, you have a good reason for caution as data shows that it can be quite costly if not proactively managed in the right manner. Luckily for you, Supreme Roofing offers snow removal services all across the nation, including New England, Denver, and Oklahoma City.
The Damage Snow Has Caused on Roofs
In February of 2015, New England accumulated over 100 inches of snow after more than a month of blizzard-like conditions. “More than 160 roofs have collapsed or faced imminent collapse since Feb. 9 in Massachusetts alone, the epicenter of this season’s roof collapse epidemic,” Sam Schultz reports for Channel 4 NBC New York News. New Hampshire had 10 roofs collapse over the course of that year as well. Snow load on commercial roofs can prove to be very costly and dangerous for property managers everywhere.
If you don’t hire snow removal services, you risk spending a great deal of money in roof repairs and replacements in the future. It’s best to take care of the snow early, than wait until it’s too late. Supreme Roofing is only a call away! Our team has been providing snow removal services for many years, and we have dealt with all kinds of weather conditions and roofs.
Uniform Vs. Nonuniform Snow Load
There are a couple of things to consider when thinking about snow load on the roof of your commercial building: uniform and nonuniform snow load.
Uniform snow load is when the snow places a vertical, downward force equally on the roof of your building. Nonuniform snow load is when you have lateral force and unequal weight distribution placed on your building with things like a snow drift.
Where property managers can run into problems is when they experience a lot of high winds (nonuniform snow load) and snow that melts, refreezes, and takes on subsequent snow on two-level roofs.
Insurance records suggest that roughly 75 percent of snow-related structural damage comes from drift loads on two-level roofs. Snow drifts can get really dangerous: snow can drift 20 feet wide by 300 feet long on different commercial buildings. This is definitely something every property manager should pay close attention to.
Usually, our team of commercial roofing experts will find little snow up on the higher roof, but it can blow from the higher to the lower level and hammer that lower roof.
How Supreme Roofing Deals With Snow On Your Commercial Roof
Throughout the country, there are varying snow load requirements that are measured in pounds per square foot – ranging from approximately 40 to 65 pounds per square foot.
Supreme Roofing measures this by cutting out a 12” x 12” square, going straight down to the roof deck, and putting that in a trash bag. Next, we measure the weight of the bag of snow on a scale to determine if we are breaching the international building code requirements for snow load. Sometimes, Supreme Roofing will bring in a structural engineer to give us expert advice on how much the snow is weighing, further ensuring we are doing what is safest and in the best interests of the property manager.
Signs That You Need a Snow Removal Fast
Some key interior visual signs to watch for in determining if you are having problems with snow load on your commercial building include:
- Deflection or separation of the roof deck
