Clean Off Your Roof
Agricultural experts are warning that heavy snows can trigger roof collapses.
Snow should be cleared from a roof if snow loads are greater than a structure can bear, or if the building shows signs of stress. In Wisconsin, state codes require roofs to withstand at least 30 to 40 pounds of snow per square foot, but agriculture buildings are exempt.
The university extension warned that removal can be dangerous, since snow can slide, burying those below. Officials suggest using a roof rake from a safe distance
