With the winter storm bringing heavy snowfall across Nevada County, the Building Department cautions residents and businesses to monitor their buildings for signs of stress from accumulating snow. With continued snow, the total weight on roofs can increase rapidly.
“Higher elevations are seeing the greatest snow totals and carrying significant weight, but we’re also concerned about buildings in the lower elevations, where snow is less common,” said Building Director George Schureck. “Even smaller accumulations can create real structural risks for buildings that may not be designed for snow events.”
Vulnerability is particularly high for manufactured homes, carports, and structures with flat or low-slope rooflines. Property owners should also be aware that buildings constructed before the implementation of modern snow-load standards in the early 1960s, or those with complex roof geometries such as parapets and saw-tooth designs, are more prone to dangerous, uneven snow drifting.
Beyond structural concerns, the accumulation of snow and ice can create severe respiratory hazards by potentially obstructing chimneys and exhaust systems, leading to a buildup of lethal carbon monoxide. To mitigate this risk, ensure all exterior vents remain clear and that portable generators are never operated indoors or near open windows.
The weight of the snow can also shift or damage gas lines and valves. If you detect a gas odor, evacuate the premises immediately and contact 911.
Residents and business owners should use caution when clearing snow from roofs, as heavy accumulations can create hazards such as falling snow or ice, damage to roofing materials, and potential contact with electrical lines or equipment.
Anyone needing assistance from a licensed professional can consult the Nevada County Contractors’ Association (NCCA) or the Contractors’ Association of Truckee-Tahoe (CATT), both of which maintain directories of qualified local contractors.
