Roof Ventilation Myths You Shouldn’t Believe


Most people don’t understand the importance of attic ventilation. Experienced roofers understand the importance of allowing fresh air into your attic and reducing moisture levels. Attic ventilation can be a roof-saver, if not a life-saver. Here are some myths and facts about it.

More Attic Ventilation Is Good

You want only the exact amount of attic ventilation. Not enough causes moisture in winter and low energy efficiency in summer. Too much can be as bad, if not worse. How much ventilation do you need? Professional roofing experts will tell you exactly.

Roof Vents Are for Warmer Climates

Too many people believe that roof ventilation is important only during the summer. Roof vents reduce hot air in summer, but there are also other ways to achieve this. Shingle color, sun exposure and insulation also help.

Moisture damage in winter does more harm to your residential roofing than the hot summer air. In warmer climates, you don’t need to worry about condensation. Thus, attic ventilation benefits you more in colder climates.

I Have Roof Vents, So That Means That I Have Roof Ventilation

Not all roof vents are so effective. Ridge vents are the most cost-effective option. Without baffles, though, they create almost no ventilation at all. Gable vents circulate air through only a small area of your attic. Static, roofline vents have leak issues. Soffit vents often trap air at the top of your attic. The most effective system is a ridge-and-soffit continuous ventilation system. Still, these designs can vary from roof to roof.
