How Does Roof Ventilation Work?

Like people, roofing systems need to breathe. In the roof, ventilation works to let the warm, moisture-filled air out of the attic and the fresh, cool air in. Its goal is to keep the attic space — and therefore the rest of the interior — cool and dry, helping keep your home in good condition.  

In this blog, Wortham Brothers roofing discusses the critical parts of roof ventilation and the problems you may face without it.

Critical Parts of Roof Ventilation

Intake ventilation is where the air enters the attic. It is located near the edges of the roof, particularly the soffits. Exhaust ventilation, on the other hand, is where air escapes from the attic. It is normally located at the peak or topmost part of the roof. A roof ventilation system that is set up properly will continually cycle air throughout the attic at all times. However, if one of these parts are missing, clogged, or installed incorrectly, it can hamper the ventilation process and keep the attic from staying cool and dry.

roof repair specialist adds that it is also important to have enough insulation in the attic to keep the heat inside the home in the winter (or out in the summer) and prevent heat transfer between the two areas.

Problems Caused by Poor Ventilation

Without proper ventilation in the attic, the space will get too hot and moisture will build up. Heat and moisture have been known to cause many issues in the attic, such as ice dams, mold growth, premature failure of shingles, pest infestation, and high energy bills. Make sure to have one sq. ft. of venting for every 300 sq. ft. of attic space to prevent these problems from occurring.
