Six concrete reasons, and one nobody mentions
Surface treatment is not magic. It is an economic and practical calculation that holds up, when the covering is still sound.
A fraction of a replacement
Replacing a shingle roof in Quebec runs $9,500 to $16,500 for a single-family home. Treatment sits in an entirely different bracket.
One day, not one week
No tear-off, no dumpster in the driveway, no hammering for three days straight. Most homes are finished before supper.
Built for our climate
Saguenay gets roughly 950 mm of precipitation and 330 cm of snow a year, with only 95 to 110 frost-free days. That cycle is what kills roofs here, and the data sheets specify protection against freeze-thaw periods.
Your home stays livable
No dust in the attic, no debris in the yard, no tarps over the windows. You stay put while we work.
The surface keeps breathing
Unlike a film-forming coating, the official data sheets state the product does not impair surface breathability. That is the direct answer to shingle manufacturers' main reservation.
Something to show at resale
A written inspection report and a treatment certificate are documents you can hand a buyer, and a pre-purchase inspector.

Replace or treat: the full picture
Replace the roof
- Full tear-off, dumpster in the driveway
- Three to five days of work
- Several tonnes of shingle to landfill
- Risk of water intrusion during the work
- Dust and debris in the attic and the yard
- Resets the clock completely, the only option if the decking is gone
Treat the roof
- No tear-off, no dumpster
- Most homes: a single day
- Nothing sent to landfill
- The roof is never opened, so no intrusion risk
- You stay home, the yard stays clean
- Not suitable if the decking is rotten or the roof already leaks
Replacement pricing comes from published 2026 Quebec ranges (asphalt shingle, single-family home, including tear-off and disposal). Treatment pricing depends on pitch, access and the condition of the covering: only the on-site inspection gives a firm price.
The seventh reason: your insurance policy
This is the angle nobody in our industry talks about, and probably the most factual one. Intact has revised its roof underwriting: standard coverage on asphalt shingle is now capped at 20 years. Beyond that, an exclusion endorsement applies with a $5,000 deductible for water intrusion, and no coverage for damage to the roof itself.
Add the reasonable-maintenance concept present in nearly every policy: a claim can be refused if the insurer establishes clear negligence. A roof under thick moss that nobody has climbed in fifteen years defends itself poorly.
Let's be precise about what a treatment does and does not do here. It does not change your roof's age as an insurer understands it, and we will not claim otherwise. What it delivers: a cleaned covering, a surface that repels water better, and a dated, documented maintenance record. In a conversation about negligence, that documentation counts.
What to know before saying yes
Treatment does not fix a leak. Active intrusion is a mechanical failure that must be repaired first.
It does not save a roof that is finished. Most granules gone, brittle shingles, soft decking: replacement is the only right answer.
The season is short. Dry surface and temperature above roughly 2 °C: in Saguenay, realistically May through October.
Your manufacturer warranty deserves a check. Several explicitly exclude products applied after installation.
What a full replacement would cost, and what you could avoid spending
Enter your roof's approximate dimensions. The math uses published Quebec market pricing, not invented numbers.
Automated estimate, for guidance only. Replacement pricing comes from published 2026 Quebec ranges: $6–$12/sq ft for asphalt shingle, $11–$21/sq ft for elastomeric membrane. The per-square-foot rate is an average. Your actual price depends on pitch, access, the condition of the covering and any repairs needed first. Only an on-site inspection gives a firm price.
Past 25 years, the condition of the covering may require repairs beforehand. The on-site inspection confirms the price.

Not sure your roof qualifies?
That's exactly why the inspection is free. We go up, we look, and we tell you the truth, even when the answer is "it needs replacing".
