Choosing the Right Siding for Montreal’s Climate

Choosing the Right Siding for Montreal’s Climate

Siding in Montreal is not cosmetic. It is a structural defense against freeze–thaw cycles, moisture intrusion, wind, and UV exposure. Material choice directly affects durability, insulation performance, and long-term maintenance costs.

Vinyl siding remains popular due to affordability and low maintenance. Quality vinyl resists moisture and does not rot, but thickness and installation matter. Inferior products crack under temperature swings. Aluminum siding performs well against moisture and fire, making it suitable for older West Island homes, though it can dent. Fiber cement siding offers superior longevity and resistance to pests, fire, and warping, but requires higher upfront investment and professional installation.

Proper siding selection balances climate resistance, insulation value, and lifecycle cost. The wrong material fails early. The right one protects the structure for decades.
