When (and How) to Shovel Your Roof After Heavy Snow
Chelsea O'Donnell
If it feels like we’ve been living inside a snow globe lately, you’re not imagining it. Connecticut has taken a serious beating this week, and while most of us have been focused on clearing driveways and walkways, there’s another place snow quietly causes trouble: your roof.
Last week, we talked about ice dams, those thick ridges of ice that form along the roof edge and trap melting snow, often forcing water back under shingles. One of the best ways to prevent ice dams is also one of the most overlooked winter maintenance tasks: roof shoveling.
So when should you shovel your roof, why does it matter, and how do you do it safely (or decide not to do it yourself at all)?
When to shovel your roof
There’s no hard-and-fast rule like “six inches equals shovel time,” but there are some clear signals. If your roof has accumulated a foot or more of snow, especially heavy, wet snow, it’s worth paying attention. The same goes if you’re seeing icicles forming along the eaves, uneven snow melt, or signs of ice dams starting to build.
Older homes, homes with flatter or low-pitch roofs, and houses with less insulation or ventilation tend to be more vulnerable. And if we’re in one of those cycles where snow melts during the day and refreezes at night (hello, New England winter), snow buildup becomes more than just a cosmetic issue. It becomes a structural and water-infiltration risk.
Why roof shoveling matters
Snow is deceptively heavy. A roof holding several inches of wet snow can be supporting thousands of extra pounds. Over time, that stress can contribute to sagging, cracks, or long-term damage, especially if your roof was already nearing the end of its lifespan.
But the bigger issue for many homeowners is water. Snow melts, water moves, and when it refreezes at the roof edge, it has nowhere to go. That’s how you end up with leaks, stained ceilings, peeling paint, and mold growth, sometimes weeks after the snow is gone.
Roof shoveling reduces the amount of snow available to melt and refreeze, helping to prevent the ice dam cycle we talked about last week before it starts.
How to shovel your roof safely
If you’re going the DIY route, safety comes first. You should never climb onto a snow-covered roof. Instead, use a roof rake with a long extension and work from the ground. Pull snow down gently, starting at the roof edge and working upward a few feet at a time.
The goal isn’t to scrape the roof bare. In fact, you don’t want to. Leave a thin layer of snow to avoid damaging shingles. And always be aware of what’s below—snow and ice come down fast and heavy, and no one wants a surprise avalanche landing on them or their landscaping.
If your roof is steep, high, or difficult to access, or if ice has already formed, that’s your cue to stop.
When to call a professional
There’s no prize for doing this yourself. Roof shoveling can be dangerous, and every winter, people get hurt trying to save a few dollars. A professional has the right tools, safety equipment, and experience to remove snow and ice without damaging your roof or themselves.
Many local home improvement companies like ours offer roof shoveling during heavy snow seasons. We already understand roofing systems inside and out, can assess whether snow removal is necessary and handle it safely when it is. That kind of experience matters, especially when ice dams or existing roof issues are in play.
Roof shoveling isn’t something most homeowners think about until there’s a problem. But paired with good insulation, ventilation, and awareness (like spotting ice dams early), it’s one more way to protect your home during a tough Connecticut winter.
If you’re unsure whether your roof needs attention, trust that instinct or call a pro. It’s always better to address snow buildup proactively than to deal with water damage once everything melts.
