5 Things to Know About Attic Ventilation - Martino Home Improvements

Improperly vented attics can cause major damage to your roof. Many homes in the U.S. have high levels of moisture due to improper ventilation. To save your roof, we?re going to go over 5 things that you need to know about attic ventilation.

1. Too Much Ventilation Is A Bad Thing
The amount of attic ventilation that you need for your home is precise. To avoid insufficient ventilation and the moisture problems that can occur, some people overdue it on their ventilation. This is a major mistake as too much ventilation can be just as bad as too little.

2. 1:300 Is the Right Ratio
To determine how much ventilation you need, you should talk to a professional. However, the general ratio is 1:300. So for every 300 square feet of ceiling, you need 1 square foot of attic ventilation.

3. Poor Insulation Lets Out Warm Air, Not Attic Ventilation
People often think that ventilating an attic during the winter will release warm air and lower heating efficiency. If you do have this problem, it?s usually due to poor insulation.

4. Roof Vents Aren?t Enough
Most types of vents trap air inside the attic, circulate air only through a smart part of your attic, or leak. Yet many home owners think that roof vents are the only ventilation they need. An inspecting with any roofing company will show you that they?re wrong.

5. Different Areas Need Different Ventilation
Ventilation needed in Michigan is going be different from that needed in Florida. Attic Ventilation is a science and is unique for different homes in different areas. This is why it?s difficult for any homeowner to decide and install their own attic ventilation. Talking to a roofing professional with experience in your region is the best way to get the best ventilation.
