Your roof needs proper ventilation. Without it, trapped heat and moisture can cause your energy costs to increase, the roof's lifespan to decrease and the risk of mold/mildew damage to skyrocket. Poor ventilation is the biggest threat to your roofing system.

Proper ventilation allows air to enter through intake vents (usually in your soffits) and exit through ridge vents, roof vents and power vents, etc. This air flow removes moisture and heat from the attic and helps prevent ice dams in the winter.

Poor ventilation can ruin your insulation, destroy your shingles, raise your energy costs, damage siding and paint and cause mildew growth. In summer, improper ventilation can cause attic heat to build in excess of 160°F!

A common mistake found in homes today is exhaust fans that push moist air into the attic rather than the outdoors. Bathrooms, kitchens and clothes dryers all require exhaust fans but all too often those fans empty into an attic, adding moisture and sometimes creating water damage.

It is estimated that nine out of 10 homes in North America do not have proper attic ventilation. Is yours one of them? Our free estimate will include a comprehensive review of your roof's ventilation system.
