Protect Your Building from Snow and Ice

February 2011 – In light of recent snow accumulations of up to 30 inches, the National Weather Service issued a statement warning building owners to clear snow from roofs and terraces.  With today’s storm depositing up to an inch of ice on top of substantial snow loads, building maintenance personnel have been advised to safely remove accumulated snow and ice to protect overtaxed roofs.

Cases of collapsed roofs and decks have already been reported across Massachusetts, Connecticut, and New Jersey.  Of particular concern are flat roofs, which do not permit snow to slide off.  Drains clogged with ice and debris further contribute to the problem.

Parking garages are also under strain from snow loads.   Avoid piling snow in a portion of the garage, which may not be able to support the weight.  Structural damage can occur when snow drifts exceeds design loads, or when heavy plow trucks drive on elevated decks.  Steel plow blades can damage parking decks and ramps already under stress from temperature cycling and freeze-thaw degradation; rubber-edged plow blades can help protect sensitive surfaces.  Use care in selecting deicing chemicals, as many can be corrosive to steel and destructive to masonry and concrete.

Continuous building usage is important, but so is building component longevity.  With a proactive snow and ice management plan, you can enable your building to safely weather the storm.
