Proper ventilation prevents ice dams, reduces energy costs and extends your roof's lifespan by 5 to 10 years.
Attic ventilation is one of the most underestimated aspects of a high-performing roof. A poorly ventilated attic creates ice dams in winter (heat rises, melts snow that refreezes at the eaves) and overheating in summer that accelerates shingle aging.
The solution is a balance between air intake (soffits) and exhaust (ridge vent or aerators). We evaluate your current setup and optimize airflow to achieve the Building Code recommended ratio: 1 sq ft of net ventilation for every 300 sq ft of attic space.
Inspection of existing ventilation — soffits, vents, aerators — and airflow ratio measurement.
Installation or replacement of soffits to ensure adequate air intake.
The most effective method to exhaust hot and humid air from the attic.
Solution performante pour les configurations qui ne permettent pas un évent de faîte.
Empêchent l'isolation soufflée de bloquer les soffites et de couper la circulation d'air.
S'assurer que la ventilation n'introduit pas d'infiltrations d'eau ou de neige.
Une ventilation adéquate empêche la fonte-regèle qui forme les digues de glace destructrices en hiver.
A well-ventilated attic reduces summer overheating and improves your insulation's efficiency.
Proper ventilation can add 5-10 years to your shingles' lifespan.
Respect du ratio de ventilation requis par le Code du bâtiment du Québec.
Warning signs: ice dams in winter, very hot attic in summer, attic mold, prematurely curling shingles. Une inspection gratuite permet de diagnostiquer le problème.
Depending on the work needed, expect $500-$3,000. The investment is quickly recouped through energy savings and extending your roof's lifespan.
We systematically evaluate ventilation during every replacement. If insufficient, we optimize it within the project — it's the ideal time.
La combinaison la plus efficace est l'évent de faîte continu avec soffites perforés. Les aérateurs Maximum sont aussi excellents pour les configurations qui ne permettent pas un évent de faîte.
