It’s discouraging: you paid to have your roof, and water is still getting in. A stain that keeps coming back on the ceiling, a drip during the rain, humidity that persists. You wonder whether the repair was bad, or whether it’s a new problem. And above all, what to do now?
The first thing to understand: a roof that still leaks after a repair deserves a new assessment, not another improvised repair done blindly. Chaining together «patches» without a diagnosis often means wasting money without fixing the cause.
In Saint-Henri, in the Lévis area, at Solutions Rénovation Québec (RBQ licence 5811-7821-01), we regularly see «repaired» roofs that still leak. In this article, we explain why this happens, what to do right away, what your recourses are, and how to fix the problem for good.
Note: we are contractors, not lawyers. For your recourses against the previous contractor, consult the Office de la protection du consommateur, the RBQ or a legal professional — we come back to this below.
Why is your roof still leaking after a repair?
It’s frustrating, but there is almost always a technical explanation. A repair that doesn’t fix the leak isn’t bad luck — it often means the wrong spot was treated, or only the symptom.
The number one trap: the point where water enters is often far from the visible stain on the ceiling. Water enters in one place, travels along the roof decking, joists or membrane, and comes out somewhere else. Repairing under the stain, without finding the true point of entry, fixes nothing. This is a common mistake.
Another cause: a repair that treats the symptom without eliminating the cause. Replacing a few shingles when the problem comes from a defective flashing, for example, will not work. And our climate doesn’t help: freeze-thaw, snow, wind and humidity can accentuate defects and create infiltrations that mild conditions were hiding. A leak that comes back after a winter, or after a heavy wind-driven rain, often points to a poorly handled waterproofing detail.
Common causes of a persistent leak
Certain causes come up constantly when a roof keeps leaking after repair. Knowing them helps to understand why the first job wasn’t enough.
Flashings, valleys and roof penetrations
This is by far the most frequent source of persistent leaks. Metal flashings — those pieces that waterproof junctions and changes in plane — are often the cause when they are poorly integrated or deteriorated.
Penetration points are other classic suspects: valleys (the hollows where two slopes meet), chimneys, plumbing vents, skylights. Water slips through these waterproofing details well before it gets through a shingle. A repair that replaces shingles without correcting a defective flashing or penetration misses the real cause. That’s why we check the waterproofing details first, rather than systematically replacing shingles.
Attic ventilation and aging of materials
Attic ventilation and humidity can also play a role. Poor ventilation promotes condensation and humidity problems that sometimes look like a roof leak without really being one. That said, you shouldn’t assume ventilation is the cause without an inspection — it’s one possibility among others.
The aging of materials also comes into play. On an old roof, a spot repair has its limits: repairing one area when the whole is at the end of its life only postpones the problem by a year or two, before a new leak appears elsewhere. The age of the roof changes the situation a lot, as we will see.
Defective repair or roof at the end of its life?
Here is the key question: is the leak persisting because of a poorly done repair, or because the roof is simply at the end of its rope? Both lead to different solutions.
Several factors guide the answer: the age of the roof, the extent of the damaged shingles, and the condition of the decking, the membrane and the waterproofing details. A recent roof that leaks after repair points more toward deficient work; an old roof with multiple problems points toward end of life.
In all cases, a diagnosis is essential before deciding between another repair and a full redo. Without understanding why water is getting in, you risk paying again for a solution that won’t hold. It is this assessment that distinguishes an informed decision from a costly gamble.
Is your roof still leaking after an intervention?
Before another blind repair, you need to find the real cause. Request an assessment from Solutions Rénovation Québec — we assess the condition of the work and the next steps to consider.
What to do immediately if water is getting into your house?
When water is actively getting in, the goal is twofold: limit the damage and document the situation. Here is what to do, in the right order, without taking risks.
Protect the interior and document the damage
The priority is to limit the damage inside while the leak is active — while staying safe.
Safety and protection measures
First, safety. Keep occupants away from areas where water is infiltrating, especially if water is approaching electrical installations (a real danger). Protect exposed belongings by moving them or covering them, and place containers to collect dripping water.
Crucial point: never go up on a wet, snowy or icy roof. It is extremely dangerous, especially in winter. If the problem requires work on the roof, call a professional equipped to work safely. Your safety comes first — a leak is managed from the inside while waiting for the intervention.
Photos, invoices and proof of repair
While the leak is active, document everything. Take photos and videos of the infiltrations and visible damage (stains, blisters, water). Gather the invoice, the contract and the description of the previous repair work.
Note the dates: when the repair was done, when the leak reappeared. Keep your communications with the contractor who did the repair. This documentation is essential — it serves both to diagnose the problem and to support a possible recourse if the repair was deficient. A well-assembled file, starting now, protects you going forward.
When is urgent intervention needed?
Some situations require a quick response. An active and significant infiltration, water near electrical installations, a ceiling showing signs of deterioration (swelling, sagging), or significant damage that threatens safety: these are emergency signals.
In these cases, you must act quickly to protect your home and your occupants, without taking personal risks on the roof. A rapid professional intervention can install temporary protection (tarp, safe sealing) while awaiting a permanent repair. The important thing is not to let water cause damage for days hoping it will sort itself out.
Have the cause of the infiltration assessed quickly
The faster the cause is found, the less damage there is. Request an inspection from Solutions Rénovation Québec — damage and the probable cause are assessed before it gets worse.
What recourse if the repair was defective?
If the repair you paid for did not solve the problem, you may have recourse. Here is the process in summary — but remember that for your specific situation, the competent organizations are your best resources. And above all, do not conclude that a repair was defective without a technical diagnosis that demonstrates it.
Check the contract and the contractor's licence
Start with the file. Identify the contractor who performed the work and check their RBQ licence — the RBQ also recommends verifying the validity of the licence and the appropriate sub-categories even before signing a contract, but this verification remains useful afterwards.
The RBQ offers a public online registry where you can confirm free of charge whether the contractor holds a valid licence and for the relevant categories (including roofing). Then review your written commitments: the contract, the description of the work, and any warranty mentioned. These documents largely determine your rights. Guaranteed work that fails quickly may give rise to a request for correction.
Document and communicate
If you believe the repair is deficient, the first step is often to report it in writing to the contractor and request a correction. Many situations are resolved this way, especially if the work was guaranteed.
Your documentation supports this approach: the contract, the invoice, the timeline of interventions and leaks, the photos, and any technical assessment. If dialogue fails, a formal communication (often called a formal notice) describing the problem and requesting a correction within a reasonable timeframe may follow. Drafting such a request and choosing the right recourse benefit from being adapted to the facts of your file — a legal professional can advise you if needed. Always keep a copy and proof of sending of your communications.
Understanding RBQ bonding
The RBQ licence bond is a separate mechanism that can, in certain situations, compensate for harm related to work by a licensed contractor. Important: it is not an automatic guarantee of satisfaction, and it has its own conditions, deadlines and amounts.
These conditions and amounts are governed by regulations, which can change — regulatory changes have also been proposed recently. That is why you should not rely on figures circulating: to know the conditions, deadlines and amounts applicable to your situation on the date of your process, check directly with the RBQ. It is the only reliable and up-to-date source on this mechanism. The courts (including small claims for eligible amounts) remain another possible avenue. To choose the best approach, inform yourself with the OPC, the RBQ or a legal professional.
A documented technical assessment helps your file
An objective finding of the cause of the leak strengthens your position. Request an assessment from Solutions Rénovation Québec — a documented diagnosis can help you prepare your discussions with the contractor concerned.
Repair again or redo the entire roof?
Once the cause is identified, the real question becomes: a new targeted repair, or a complete overhaul? The answer depends on the actual condition of your roof. Let's see how to decide.
When a localized repair may be enough
A targeted repair can solve the problem durably under certain conditions: when the damage is limited and the cause clearly identified, when the general condition of the roof is still satisfactory, when the materials are compatible, and when the waterproofing details (flashings, penetrations) are properly addressed.
In other words, if your roof is relatively recent and in good condition, and the leak comes from a specific point (a flashing, a valley) that can be properly corrected, a well-done repair is enough. The key is that this time, the real cause is addressed — not just the symptom. That is precisely what was missing from the previous repair if it failed.
When to consider a complete overhaul
In other cases, repairing only postpones the inevitable. A complete overhaul becomes logical when the roof shows generalized aging, multiple leak zones, deterioration of the decking or other components, or when the cumulative cost of repeated repairs and the uncertainty about remaining lifespan no longer justify continuing to repair.
When a roof is at the end of its life, each repair only buys a few months before the next leak elsewhere. At a certain point, doing it properly costs less and provides far more peace of mind than chaining together patches. An honest diagnosis will tell you which situation you are in — and a good contractor will not push you toward an overhaul if a repair is enough.
Roofing costs in Lévis
The cost depends on several factors: the roof area, the slope, the materials (asphalt shingles, metal), accessibility and the condition of the substrate. The ranges circulating are indicative estimates to be verified, not fixed rates.
A targeted repair obviously costs much less than a complete overhaul — but an overhaul solves the problem for years and avoids repeated repairs. One sometimes hears a «rule» like «if repairs approach a certain percentage of the cost of a new roof, it's better to redo it.» It is a useful benchmark, not an absolute standard: the decision depends on the actual condition of your roof. An on-site assessment gives the only reliable figure for your situation.

Why choose an RBQ contractor for your roof in Saint-Henri?
A roof that still leaks after repair is often a sign that a more rigorous approach is needed. The choice of contractor makes the difference between a leak finally fixed and another repair that fails.
An approach adapted to Quebec homes
We know the roofs of single-family homes and bungalows in the region, including older buildings that require particular attention. Our climate imposes its demands: freeze-thaw, snow, wind, humidity — all factors that create infiltrations if the waterproofing details are not impeccable.
Our approach starts with diagnosis: finding the true entry point of the water, not just repairing under the stain. We assess the materials, flashings, penetrations and execution details. It is this rigor that solves persistent leaks — the ones that quick repairs fail to correct.
Solutions Rénovation Québec: marks of trust
We operate under RBQ licence 5811-7821-01, led by Marco Savoie, with more than 500 projects completed, more than 10 years of combined experience and a 5-year warranty on labour, according to applicable conditions. We focus on free, no-obligation quotes, direct communication, clear project management and clean, safe worksites.
These commitments protect you — especially after a bad experience with a repair that did not hold. You know who you are dealing with, what is agreed, and you have a warranty on the work. That is exactly what is needed to resolve a persistent leak with confidence.
Fix your leak for good

Myths and realities about roof leaks
A few preconceived ideas deserve to be corrected. Here is the truth from the fiction.
«If the roof still leaks, the repair must have been bad.»
Reality: not always. The leak may come from a new entry point, or from a roof at the end of its life where each repair only lasts a while. You should not conclude that a repair was defective without a diagnosis that demonstrates it.
«Replacing the shingles fixes all leaks.»
Reality: no. Most leaks come from waterproofing details — flashings, valleys, penetrations — not from the shingles themselves. Repairing without addressing these details often leaves the leak persisting. The diagnosis must find the true entry point.
«The stain on the ceiling indicates where the leak is.»
Reality: rarely. Water travels along the decking and joists before emerging, often far from its actual entry point. Repairing under the stain without finding the true source fixes nothing. It's a classic mistake.
«A warranty automatically covers any new leak.»
Reality: it depends on the warranty, its conditions and the cause of the leak. A contractual warranty has specific terms. Check exactly what it covers, and distinguish it from legal obligations and the RBQ surety bond.
FAQ – Roof leaking after repair in Saint-Henri
Why is my roof still leaking after a repair?
Often because the repair treated the symptom without finding the true entry point of the water, which may be far from the visible stain. Flashings, valleys and penetrations are frequently the cause. Sometimes it's also a roof at the end of its life. A diagnosis identifies the true cause.
Should I contact the same contractor?
If the work was covered by a warranty, yes, you can report the problem to them in writing and request a correction. Document your exchanges. Depending on your contract and the situation, this is often the first step. If dialogue fails, other remedies exist — inform yourself with the OPC or the RBQ.
How much does a roof repair cost in Lévis?
It depends on the surface area, the slope, the materials, the accessibility and the condition of the substrate. A targeted repair costs much less than a complete redo, but prices vary widely. An on-site evaluation gives an accurate figure for your roof — be wary of fixed rates advertised without having seen the roof.
Can a roof leak cause significant damage?
Yes, if it is ignored. Water can damage the insulation, the decking, the framing, the ceilings and the walls, and promote mold. A small problem treated early avoids costly damage. That's why you must act as soon as a leak persists, rather than waiting.
Should I have my roof inspected by an independent professional?
It can be useful, especially in the event of a disagreement with the contractor who made the repair. An independent assessment provides an objective finding of the cause of the leak, which helps to understand the work required and to support a possible recourse. In a litigious situation, it is often an asset.
Does the contractor's warranty automatically cover a leak?
Not automatically — it depends on the terms of the warranty and the cause of the leak. A contractual warranty has specific conditions that must be read. It also differs from legal obligations and the RBQ surety bond. Check exactly what your warranty covers and communicate with the contractor.
How do you verify a roofer's RBQ licence?
The RBQ offers an online public register where you can check free of charge whether a contractor holds a valid licence and for the appropriate sub-categories (including roofing). Consult the Régie du bâtiment du Québec register. It is a simple check, ideally to be done before hiring.
When should a roof be replaced rather than repaired?
When it shows generalized aging, multiple leak zones, deterioration of the decking, or when repeated repairs no longer hold. At a certain point, redoing costs less than chaining repairs. A diagnosis evaluates the age, general condition and extent of the damage to decide.
A leak that persists can be fixed — but with method
Ultimately, if your roof is still leaking after repair in Saint-Henri, the solution is not another blind repair. It is a methodical approach: protect your interior, document the damage, have the real cause assessed, and check your recourses if the repair was deficient.
Above all, remember that the water entry point is often far from the visible stain, and that most leaks come from waterproofing details — flashings, valleys, penetrations — not from the shingles. Without a good diagnosis, you repair the wrong spot and the leak returns. That is what explains so many failed repairs.
And before concluding that the previous repair was defective, a technical finding is needed to demonstrate it — sometimes, it is simply a roof at the end of its life. An RBQ contractor who diagnoses rigorously, finds the real entry point and proposes the right solution (targeted repair or full redo depending on the actual condition), that is what turns a recurring leak into a problem finally solved.
