A proper roof installation is more than just laying down shingles to exact manufacturer specifications. No matter where you are in the country, ensuring adequate attic ventilation is essential in keeping the whole roofing system intact and preventing issues that are too costly to repair. Residential roofing contractor DePalma Construction explains its importance below.

Roof and attic ventilation

About Roof Ventilation

A roof’s ventilation system is composed of vents that serve two key functions. First, it allows cool, fresh air to enter the attic at the eave or soffit areas of the roof via the intake vents. Second, it draws out hot, moist air from the attic through the exhaust vents located on top of the roof.

Efficient attic ventilation provides year-round benefits for both residential and commercial roofing systems. These include cooler and drier attics in summer and winter, respectively, as well as protection from damage to materials and structure and lowering energy consumption.

The Damaging Effects of Heat and Moisture Inside Attics

Letting heat and moisture linger inside your attic due to a lack of ventilation can have damaging effects on your roof. When it’s hot outside, the sun beating down on the roof can increase attic temperatures. Heat can’t escape the attic, causing shingles to age prematurely and the roof’s decking to warp. It can also radiate down to your indoor living areas, resulting in comfort and energy consumption issues.

Meanwhile, below-freezing temperatures can lead to ice dam formation along the eaves due to a lack of ventilation. Humidity is also an issue during the colder months. As it enters the cool attic, it condenses into a liquid as it meets a colder surface. If left unaddressed, moisture can seep through the roof’s wooden components, compromising its structural integrity.
