1. The More Attic Ventilation, The Better

One of the myths we hear the most frequently is that more attic ventilation is always better. Unfortunately, just as is the case with air conditioning units and furnace capacities – more is not always better. While too little attic ventilation is definitely an issue, having too much may be an even bigger risk.

Roof vents create more access to the inside of your home, so having too many can increase the risk of leaks, weak spots for storm damage, or sparks entering your home and causing destruction on the inside.

This leaves the question: how much ventilation is just right?

2. Roof Vents Equals Attic Ventilation

Simply having roof vents does not mean that you have adequate attic ventilation. Depending on your home, roof and type of roof vents, your roof vents may not do much of anything for your attic ventilation. Each home and roof is unique, so the best way to ensure that you have proper attic ventilation is to hire a professional to install a ventilation system that will work for you.

3. Roof Vents Allow Warm Air to Escape During Winter

Many people fall into the belief that attic ventilation causes lower energy efficiency due to warm air rising. However, if your warm air is rising straight up to your attic and out of roof vents, you have bigger problems than attic ventilation.

Chances are, if warm air is escaping through roof vents during the winter, you have an insulation problem. Unfortunately, insulation problems can also increase moisture – meaning that attic ventilation remains a considerable concern as well.

4. Only Warmer Climates Need Roof Vents

This statement normally originates from people who assume roof vents are only to increase energy efficiency in the summer by allowing heat to escape – and while this is a benefit of good attic ventilation, there are other pieces that are better designed for energy efficiency. Shingle color, sun exposure and insulation each contribute more to energy efficiency.

However, attic ventilation is still very necessary, even in cooler climates. In fact, colder climates tend to benefit even more from proper ventilation than warmer ones. Colder climates have to worry more about condensation in the attic due to the chill outside, meaning that proper ventilation to keep moisture levels low is infinitely more important.
