Every winter, snow accumulates on the roofs of Saint-Jean-Chrysostome. That's to be expected. What's not normal is when homeowners wait too long before taking action.
The result: ice dams, water infiltration and even the risk of collapse. These problems occur mainly on houses 25 years and older, but no roof is safe if it isn't well maintained or poorly ventilated.
At Solutions Rénovation Québec, we regularly intervene in Saint-Jean-Chrysostome and throughout Lévis to repair damage that could have been avoided. The good news is that, with the right preventive measures, your roof can make it through the winter worry-free.
Risks associated with snow and ice dams
Snow on a roof isn't just a question of aesthetics. It's a question of weight, heat and freeze-thaw cycles.
When snow accumulates, it can create a significant load on the structure. But the real danger is often what happens when it starts to melt.
The impact of Saint-Jean-Chrysostome's climate on your roof
In our neck of the woods, we experience between 50 and 100 freeze-thaw cycles per winter (a reasonable estimate). This means that the snow melts a little during the day, then refreezes at night.
This cycle creates what are known as ice dams, or ice dams. The snow melts because of the heat escaping from the attic, the water runs down to the gutters, then refreezes in solid blocks. The water then remains trapped behind these dams, eventually seeping under the shingles.
When accumulation exceeds 50 cm, the risk increases by around 40 % (reasonable estimate). Without adequate ventilation, the durability of your roof can decrease by 15 to 20 % over its expected lifetime.
Frequent consequences for homeowners
It is estimated that 20 to 30 % of winter claims in Quebec are related to unplowed or poorly managed snow (a reasonable estimate). Seepage causes stains on the ceiling, mold in the attic, and sometimes major structural damage.
It can also affect occupants' health. Moisture promotes mold growth, especially in poorly ventilated attics. And if the homeowner climbs onto the roof to clear snow without proper equipment, there's a real risk of falling.
SRQ solutions to prevent snow damage
Protecting your roof means understanding how it reacts to cold. Then, it's about implementing sustainable solutions.
We don't just recommend snow removal. Our goal is to reduce or eliminate the need for annual emergency interventions.
Ventilation and insulation to prevent ice dams
A well-ventilated roof keeps the attic close to the outside temperature. As a result, snow doesn't melt from underneath and create ice dams.
We install ventilated soffits and ridge vents, and make sure that air circulates properly between the insulation and the roof sheathing. We also add baffles to prevent the insulation from blocking the air flow.
On the protection side, we can install ice shield membranes on critical sections: bottom of slopes, valleys, around chimneys. These self-adhesive membranes prevent water from seeping through, even if a dam forms.
For new or renovated roofs, we prefer shingles that are resistant to freeze-thaw cycles and designed for the Quebec climate. We also perform bi-annual inspections - one in spring, one in fall - to detect problems before they become costly.
Professional snow removal and safety
When the accumulation becomes too great, snow removal becomes necessary. But climbing onto an icy roof without a harness or training is dangerous.
Our snow-clearing operations generally cost between 500 and 1,000 $, depending on area and access. We use plastic shovels to avoid damaging shingles, we work with harnesses, and we know where to put our feet.
We intervene mainly on steeply pitched roofs or on houses where the attic is not properly ventilated. The aim is to remove the overload without creating new problems.

Cost and return on investment of preventive solutions
Investing in prevention costs less than repairing water damage. It's as simple as that.
Professional snow removal costs a few hundred dollars. Repairs following an ice dam can easily cost between 2,000 and 6,000 $. A complete overhaul after repeated seepage can cost between 7,000 and 12,000 $.
Cost estimates for homeowners Lévis/Saint-Jean-Chrysostome
Here's what we regularly see in the region:
Professional snow removal 500 to 1,000 $ per intervention Ice dam repair 2,000 to 6,000 $ (depending on extent of damage) Partial re-roofing 7,000 to 12,000 $ for a damaged section Improved ventilation + windscreen 3,000 to 6,000 $ (one-off investment)
In comparison, improving ventilation and installing windscreen membranes gives a return on investment in 3 to 5 years, especially if it avoids a single major repair.
Subsidies and financial assistance
The Rénoclimat program sometimes offers grants for attic insulation and ventilation. This can cover part of the cost if the work improves the home's energy efficiency.
We can guide you through the process if your project qualifies. Every situation is different, but it's worth checking out.
Myths and realities about snow and roofing in Quebec
We hear a lot about snow and roofing. Some are true, others not at all.
Here's what we see regularly, and what's really happening in the field.
Common myths
«Snow is natural insulation».» False. Snow can provide some protection against the cold outside, but if it melts underneath because of the heat in the attic, it creates ice dams. This is the opposite of protection.
«I can clear the snow myself, it's so easy».» Not really. Climbing onto a snow-covered, icy roof without equipment means risking a serious fall. What's more, using a metal shovel or pulling too hard on the shingles can damage the coating.
«Ice dams are only for old roofs».» No. All roofs can be affected if the ventilation is poor or the insulation lets too much heat through. Even a poorly designed new roof will have problems.
«The heat in the house melts the snow, that's normal».» That's the problem. If the heat rises to the roof, the insulation or ventilation is inadequate. Snow should stay cold and not melt.
«My roof is new, I don't need to clear snow».» An accumulation of more than 50 cm is heavy. Even a new structure has its limits, especially if the slope is shallow or the building was designed for lower snow loads.
Facts verified by SRQ and manufacturers
Here's what really works:
Good ventilation and insulation eliminate most ice dams. Biannual inspections detect problems before they cause damage. Ice-barrier membranes, installed to RBQ standards, protect critical areas even if a dam forms.
And above all: doing things right from the start is always cheaper than fixing them after the fact.

FAQ: Roofing and snow in Saint-Jean-Chrysostome
Which snow accumulation requires professional snow removal?
As a general rule, an inspection is recommended after 50 cm of accumulation. If the slope is shallow, or if you see signs of overloading (doors jamming, creaking), you need to act quickly.
How does ventilation reduce the risk of ice dams?
Good ventilation keeps the attic cold, at the same temperature as the outside. Snow doesn't melt from below, so it doesn't create ice dams. This is the most effective long-term solution.
DIY snow removal: what are the risks and limits?
Falls are the main risk. A snow-covered, icy roof is slippery. Without a harness or training, it's dangerous. What's more, improper snow removal can damage shingles and flashings. If you're not comfortable, call in the pros.
What is the average cost of a winter inspection in Lévis/Saint-Jean-Chrysostome?
A basic visual inspection can be free if combined with a quotation. A full inspection with detailed report usually costs between 150 and 300 $. SRQ offers free on-site estimates.
Are windscreen membranes compulsory?
According to the Quebec Construction Code (Chapter I, Building), ice barrier membranes are mandatory in certain critical areas, especially if the slope is shallow. It's an essential protection against infiltration.
What subsidies are available for snow prevention and ice dams?
The Rénoclimat program can cover part of the cost if you improve the insulation and ventilation of your attic. Criteria vary, but it's worth checking your eligibility.
What inspection frequency does SRQ recommend?
Two inspections a year are recommended: one in the spring to check for winter damage, and one in the fall to prepare the roof for snow. This is the best way to detect problems early.
How long does a snow removal operation last?
It depends on surface area and build-up, but generally between 2 and 4 hours for a standard single-family home. We work fast, but we never rush things to the point of compromising safety or damaging the roof.
Can heating cables be installed to prevent ice dams?
Yes, but that's not our first recommendation. Heating cables consume electricity and don't solve the cause of the problem. We prefer to correct ventilation and insulation, which are permanent solutions and more economical in the long term.
How do I know if my attic has enough ventilation?
If you see ice forming on the edges of the roof during the winter, or if your attic is much warmer than the outside, it's a sign of poor ventilation. A complete assessment can be made during a free visit.
Do all types of shingles withstand ice dams?
No. Some lower-end shingles deteriorate faster when water infiltrates. We recommend quality shingles designed for the Quebec climate, with ice barrier membranes properly installed underneath. It makes all the difference.
What happens if I do nothing and the snow accumulates all winter?
At best, nothing. In the worst case, partial or total roof collapse, especially if the structure is weakened or if the accumulation exceeds what the roof was designed to withstand. In between, water infiltration, mold and costly spring repairs.
Conclusion: protecting your roof from cold and snow
Snow is part of our Quebec winters. We can't avoid it, but we can manage its effects on our roofs.
With proper ventilation, well-installed windshield membranes and regular inspections, you can considerably reduce the risk of damage and infiltration. And if a winter is particularly harsh, professional snow removal can help you avoid costly problems.
At SRQ, we don't sell miracle solutions. We do what needs to be done, according to RBQ standards, with materials adapted to the Quebec climate.
