Why should you Cent an Attic?

How will the right attic ventilation protect the roof? When it comes to attic ventilation one may think it's just air and how could it impact an asphalt shingle roof. Well, the right attic ventilation is a system that balances exhaust and intake vents to allow smooth airflow throughout the year, helping reduce moisture buildup and heat. There are many different systems for giving important exhaust and intake.

If the right airflow isn’t there, early shingle deterioration and roofing system failure can occur. In winters moist warm air created by cooking, heating appliances, showering, and other activities in the living space rose into the attic. Without non-stop flow of outside air, the water vapour cannot escape. Trapped water vapour and moisture generated in the interior cannot escape. This moisture can lead to wood rot, mildew, mold, and wet insulation. To add to this warm air that’s trapped could condense on the cool roof deck’s underside causing more moisture-related issues in cooler climates.

Warm attic space, when warmer than outside, may cause snow on the roof to melt. This melted snow forms an ice dam near the gutters after refreezing. This will create leaking and damage to the gutter, shingles, and the roof system. During the summers humid, hot air is unable to escape which cause high temperatures in the attic region forcing the air conditioners to work harder, adding to the energy costs. But when roofing systems absorb heat and combines it with humidity related moisture, possible roof failure and rotting may still occur. Avoid these problems by installing a foil blanket insulation.
