Winter Roof Maintenance: Protecting Your Metal Building
Posted on November 17, 2025 by Ceco Building Systems
As the long, hot days of summer fade and winter begins to settle in, the season brings its own charm – snow on rooftops, the smell of wood-burning fireplaces and kids hoping for a day off from school. While others enjoy the colder months, building owners and facility managers need to focus on something important overhead: the roof of their metal building.
The Risks of Snow and Ice Buildup
Snow and ice may appear peaceful, but they can pose challenges for metal buildings. When heavy snow collects on the roof, the extra weight can strain roof panels and structural framing. Steeper roofs may shed some snow, but cold surfaces often retain more than expected. Ice can also form in layers, which increases weight and can cause water to back up under panels. If this buildup goes unnoticed, the structure may experience unnecessary stress or early signs of wear.
How to Prevent Snow and Ice Accumulation
Preparation is one of the best ways to protect your roof through the winter season. A few helpful steps include:
- Install Snow Guards: These devices help break up large sheets of snow or ice before they slide off the roof. This reduces sudden impact, protects gutters and increases safety around the building.
- Add Heat Tape: Placing heat tape in gutters and downspouts helps keep water moving during freeze and thaw cycles. When meltwater has a clear path to drain, you lower the chance of ice dams and reduce strain on the roof edges.
- Check Drainage Paths: Clear debris from gutters, drains and scuppers before temperatures drop. Good drainage allows snowmelt to leave the roof quickly instead of refreezing on the surface.
When Prevention Is Not Enough
Even with strong preparation, winter storms can still leave large amounts of snow on your roof. Fresh snow usually weighs around 10 to 12 pounds per cubic foot, but once it compacts or absorbs rainwater, the weight rises quickly. One storm or a series of freeze and thaw cycles can push a roof load close to capacity.
It is important to pay attention to early warning signs. If interior ceilings look uneven, if purlins appear stressed or if doors and windows become harder to open, the structure may be carrying more weight than intended.
Safe Snow Removal Tips
Removing snow from a metal building roof requires caution and the right approach. Keep these guidelines in mind:
-
- Consult a Professional: Before removing any snow, contact your metal building manufacturer or a structural engineer. They can help you understand the roof load capacity and advise you on safe removal methods.
- Remove Snow Evenly: Clear snow in small layers of about six inches at a time across the entire roof surface. Removing snow from only one section can create an uneven load that places stress on the structure.
- Refer to Trusted Resources: The Metal Building Systems Manual provides detailed guidance on proper snow removal techniques for metal buildings. Reviewing these recommendations can help you avoid mistakes.
- Use Safe Tools: Avoid metal shovels or sharp tools that can damage roof panels. Choose plastic snow rakes or soft-edge tools to protect the surface.
Stay Ready for Winter
With the right preparation and awareness, you can protect your Ceco metal building from the challenges that winter weather brings. Managing snow loads, maintaining drainage systems and acting quickly when buildup occurs can help reduce repair costs and extend the life of your roof.
A little attention now can help you navigate the winter season with confidence, knowing that your building is well-prepared for whatever the weather brings.
