Why waiting is the worst strategy
In Quebec, roofs undergo extreme thermal stress, going from +35°C in summer to -30°C in winter. Waiting for the roof to leak before replacing it often leads to enormous hidden costs: rotting of the wooden deck, mold in the attic insulation, and damage to interior ceilings. A roof replaced at the right time costs up to 30% less than an emergency replacement after water damage. We highly recommend booking a preventative inspection every year.
The 5 unmistakable signs: checklist
-
1. Curled or buckled shingles
The edges of the shingles lift. Wind can now easily infiltrate and tear off large sections during the next storm.
-
2. Missing or cracked shingles
Dark spaces or completely missing shingles following strong winds. The underlying membrane is directly exposed to UV and weather.
-
3. Accumulation of granules in gutters
Granules protect the asphalt from the sun. Minor losses are normal, but piles of black sand in downspouts mean the shingle is "cooked" and crumbling.
-
4. Signs of moisture or ceiling stains
Water damage visible from inside the house often indicates that a small leak has been active for months in the attic without you knowing.
-
5. Presence of dark moss or algae
On a shaded roof, moss holds moisture on the shingles. In winter, this moisture freezes, expands, and destroys the structure of the asphalt shingle. During heavy snowfall, it is wiser to use our expert snow removal services.
