King County: Use caution with rooftop snow loads

King County warning about snow on roofs

Heavy snow, followed by rain creates a potential hazard with snow loads on rooftops and awnings, which could lead to structural collapse or sliding snow.

The King County Department of Development and Environmental Services (DDES) urges the following precautions:

• If a roof is in eminent danger of collapse, stay away from the structure and call 9-1-1 for emergency help.
• Removing snow from your roof with a shovel can trigger unexpected snow slides causing crushing/suffocating injuries or death. Keep people and animals away from potential slide zones. It is strongly recommend not to access your roof to clear snow. Consider hiring experts who have experience and specialized equipment for safely clearing snow or ice.
• Clear any accumulation of snow around side wall vents for appliances.
