Attic ventilation services
Extend the life of your roof with proper attic ventilation
Genesis Roofing offers the professional attic ventilation Toronto homeowners have come to depend on — keeping your roof cooler in summer, preventing frost buildup in winter, and slowing shingle deterioration over time.
These systems function by pushing continuous, outside air into your attic in order to remove heat and moisture. Proper ventilation means your roof and attic stay cooler during those hot summer months, and it also prevents frost from building up beneath your shingles in the winter.
As well, attic ventilation will extend the life of your shingles, prevent roof rot, and slow the deterioration of your roof over time.
A combination of insulation and vents keeps roofs cool by allowing the natural flow of outdoor air into the attic. Use both rafter vents and soffit vents, and avoid covering soffit vents with insulation.
An attic fan draws in cooler air from outside while pushing out hot air. Your attic should be well-sealed so fans don't pull conditioned air from your home and drive up your energy bill.

How do I know if my attic needs maintenance?
Not sure if your attic is properly ventilated? Genesis Roofing has a few tips. Be on the lookout for these signs that may indicate your attic is unventilated or under ventilated:
- Check your eaves and roof for vents. Don't have any? Then you need some — some vents are harder to spot than others, so do a thorough search.
- Feel your ceiling on a warm, sunny day. If it's hot, your attic is even hotter and needs better ventilation.
- See thick ridges of ice on your eaves in winter? That's a sign of poor ventilation and can lead to ice dams that damage your roof's structure.
- Take a flashlight and inspect your attic during winter. Dampness or frost means warm, moist air has escaped your living space into the attic.
Attempting to ventilate the attic on your own can be very difficult if you're not a professional, and you may not realize you're causing more harm than good until the damage has been done.
