How Snow Load Can Affect Roof Structure and Safety

Heavy Snow Is More Dangerous Than You Think

We all love the peaceful look of snow-covered rooftops—but when snow piles up too high, it can become a serious threat to your home’s structural integrity.

Here’s what you need to know about snow load and how to protect your home from collapse or costly damage.

❄️ What Is Snow Load?

Snow load is the weight of accumulated snow and ice on your roof. The average roof can support about 20–40 pounds per square foot, but that varies depending on:

• Roof pitch

• Framing style

• Material used

• Snow type (wet snow weighs more than dry snow)

If snow isn’t shedding properly, the risk goes up quickly.

⚠️ Signs of Overloaded Roof

Watch out for these warning signs:

• Creaking or popping sounds

• New cracks in drywall or plaster

• Doors that suddenly stick

• Sagging ceiling lines

• Leaks or wet spots near the attic

If your roof is showing any of these signs after a snowfall, it needs immediate attention.

🧹 Should You Remove Snow from Your Roof?

In some cases, yes. Especially if:

• You have a flat or low-slope roof

• The snow is wet and heavy

• Ice is forming under layers of snow

Use a roof rake from the ground or call a professional—never try to walk on a snow-covered roof.

🛠️ Structural Repairs and Inspections

If your home is older or has been through multiple severe winters, it’s worth having your trusses and rafters inspected for bowing, cracking, or load fatigue.
