Snow accumulation on roofs is a significant concern for homeowners in colder climates. Effective snow removal is crucial to prevent damage to the roof and underlying structures and to ensure the safety of inhabitants. This article outlines best practices for snow removal, the science behind snow-related roof stress, and guidelines for when to remove snow to prevent damage.
Understanding Roof Snow Load
Snow load refers to the weight of snow that a roof can safely support. Exceeding this limit can lead to roof damage or collapse. It's important to understand both the density and depth of the snow, as these factors influence the overall weight load on your roof.
Calculating Snow Weight
Dry, Light Snow: Typically, ten inches of dry snow equates to one inch of water, or about five pounds per square foot of roof space.
Wet, Heavy Snow: One inch of water depth from melted snow can weigh approximately five pounds per square foot. Therefore, wet snow is significantly heavier than dry, fluffy snow.
Regional Snow Load Standards
Standard Guidelines: In regions like Coeur d'Alene and Post Falls, building codes specify that roofs must handle about 40 pounds per square foot, accounting for snow and other loads.
When to Remove Snow from Your Roof
Removing snow from your roof is not just about the depth of snow; it's about understanding the changing conditions and the type of snow.
Optimal Timing for Snow Removal
1-2 Feet of Snow Accumulation: As a general rule, consider removing snow once it reaches one to two feet in depth, especially if it's wet or packed snow, which is heavier.
After Severe Weather: Following storms or rapid accumulations, it's wise to remove snow to prevent the buildup from compressing and becoming ice, which adds significant weight.
Techniques for Safe Snow Removal
Effective and safe snow removal protects both the structure and the individuals performing the task. Here are key techniques and tools:
Tools and Equipment
Snow Rakes: Use specially designed roof snow rakes to remove snow safely from the ground.
Plastic Shovels: If accessing the roof, use plastic shovels to prevent damage to roofing materials.
Professional Snow Removal
Hiring Professionals: For safety and efficiency, consider hiring professional snow removal services, especially for steep or high roofs. Professionals, like those at Summit Exteriors in Coeur d'Alene, ID, are equipped with the necessary tools and experience to safely remove snow without damaging your roof.
Preparing Your Roof for Winter
Preventative measures can reduce the need for frequent snow removal and protect your roof from winter damage.
Insulation and Ventilation
Enhance Attic Insulation: Proper insulation keeps heat within your home, preventing the uneven melting of snow on the roof.
Improve Ventilation: Good attic ventilation allows cold air to circulate and reduces the risk of ice dams.
Regular Inspections
Pre-Winter Inspection: Have your roof inspected by professionals to ensure it is in good condition to withstand winter stresses. This includes checking for damaged shingles, ensuring gutters are clear, and confirming that flashings are sealed.

Understanding when and how to remove snow from your roof is critical to maintaining the structural integrity of your home during the winter months.
