Attic Ventilation 101

The word “Ventilate” is a Latin word that means “to fan.” This is simply just the act of moving air. Push out the hot, and filter in the cool. This is the process of how ventilation works. Every time old air in your attic or living spaces is vented out and fresh air is pulled in to replace it, you have a very simple air exchange happening in your home.

Attic ventilation performs two main functions: it lowers attic temperatures and removes extra moisture from the room. Lowering the temperature in the attic can help bring down AC energy costs and roof temperature. This optimizes the life of your roof and lowers the possibility of ice damage when it gets cold. Areas with hot summers and colder winters can suffer the effects of both types of issues within their attics. When it is hot outside and the sun is beating down on the roof you will notice an increase in the temperature of the attic. Exposure to this excessive heat can warp the roof sheathing and distort and prematurely age the shingles. In the winter months, excessive ice and snow can likely cause problems as well.
