How Much Snow Can Your Home’s Roof Safely Support?

SkyRight, Coeur d’Alene’s trusted roofing expert, provides vital insights into how snow impacts your roof. Knowing how much snow your roof can handle is crucial for avoiding costly damage or dangerous structural failures during winter.

Understanding Snow Load on Roofs

1. Types of Snow

  • Fresh Snow: Lightweight, averaging 3–5 pounds per square foot.
  • Packed Snow: Denser, weighing 15–20 pounds per square foot.
  • Ice: The heaviest, weighing approximately 57 pounds per cubic foot.

2. Calculating Roof Load Capacity

Roof load capacity depends on factors like material, design, and age. Most residential roofs are built to handle 20–40 pounds of snow per square foot. However, older or damaged roofs may have reduced capacity.

3. Risks of Excess Snow Load

  • Sagging Roof: Indicates structural stress that could lead to collapse.
  • Cracks in Walls or Ceilings: Result from pressure transmitted through the roof structure.
  • Roof Collapse: A rare but catastrophic outcome of excessive weight.

Did you know? A cubic foot of wet snow weighs up to 20 pounds, meaning just 2 feet of accumulation could put severe stress on your roof.

Tips for Protecting Your Roof from Snow Overload

1. Regular Maintenance

Ensure your roof is in good condition before winter. Address loose shingles, weak spots, or damaged supports.

2. Professional Inspections

Schedule inspections with certified contractors like SkyRight to assess load-bearing capacity and potential vulnerabilities.

3. Snow Removal

Use a roof rake for safe, ground-level snow removal. Avoid climbing onto icy roofs, which is dangerous without proper equipment.

4. Reinforce Your Roof

Add additional supports or upgrade materials to increase load-bearing strength.

5. Insulate and Ventilate

Proper insulation reduces the risk of ice dams, which trap snow and add weight.
