Are you one of those homeowners that don’t give a thought about attic ventilation or roofing? I suggest you should start doing so because to avoid falling victim to trending myths about attic ventilation. These myths do not hold any bit of truth, so you have to debunk them.
Ridiculous Myths About Attic Ventilation
Several myths spread about attic ventilation. However, we are going to pick out a few of them and discuss them in this article.
These myths include:
1. Roof vents are needed only in hot weather
2. Vents discharge warm air at winter
3. Installing roof vents shows your attic is in good conditions
Let’s explain more about these myths and know if they are right or wrong notions.
Roof vents are needed only in hot weather
This is a huge mistake and a wrong consideration. Roof vents are needed in both hot and cold weather conditions, even in regions where they experience the four seasons.
Many homeowners believe that attic ventilation is made only for making a building energy-efficient in hot seasons. This is accepted because warm weather is the period when hot air goes in and out of the house. The fact is, it is more than that – moisture is also a point to consider.
A proper ventilation system is needed to suck out moist air and blow in drier and cooler air. You are bound to face mildew and mold issues if your ventilation system is trapping damp air in your attic. Also, this might open some parts of your roof to rot or damage.
Vents discharge warm air at winter
Many people would say that hot air goes up, so heated air from inside your home travels out of the house through the attic. This is very wrong! That is not how roof vents function.
The air in the attic shouldn’t be heated or cooled by the HVAC system. When the insulation is not working perfectly, that’s when warm air passes through your attic in winter. The temperature in the attic vent should be almost equal to the one outside.
Installing roof vents shows your attic is in good conditions
If you have some exhaust ventilation on your roof, it is not a sign that your attic is correctly vented. A standard and professional ventilation system needs both exhaust and intake vents. At times, these vents get blocked and in cases like this, the system malfunctions.
Your roof must be inspected at least once a year by a professional roofer. The ventilation system should be checked to make sure it is working correctly. Roofs are vulnerable to severe damage when the ventilation stops working and could lead to full roof replacement.
As a homeowner, any time you notice a sign that your roof vent is malfunctioning, you can call for an inspection. Ensure that your shingles, roof vents, and other roofing components are in perfect working condition. Lastly, do your best to stay off any myth related to the attic ventilation.
