Q: How important is attic ventilation?
A: Proper attic ventilation is essential in Ontario’s changing climate. With hot summers and freezing winters, your attic experiences extreme temperature shifts that can impact the performance and lifespan of your roof.
In the winter, poor ventilation can lead to trapped warm air in the attic, which contributes to ice damming and attic condensation. This moisture buildup can cause mold growth, insulation damage, wood rot nd structural deterioration.
In the summer, inadequate ventilation allows excessive heat to build up, which can prematurely age shingles, reduce energy efficiency and increase cooling costs.
A properly balanced ventilation system helps regulate temperature and moisture year-round, protecting your roof, improving energy efficiency and extending the life of your roofing system.
