Benefits of ventilation system in your attic
Proper ventilation in your attic is a crucial factor of roof installation. It ensures that the cool and fresh air enters the attic at your roof’s eave or soffit. It also ensures that hot and moist air leaves the attic. Below are some benefits of having a well-ventilated attic:
Keeps ice damming at bay
If your property is in a cold climate, proper attic ventilation mixes cool air from the outside with air in the attic. This ensures that snow melts on the roof less, keeping ice damming at bay.
Gets rid of moisture
In warm climates, if your attic is well ventilated, hot air will be expelled. This hot air is moist and could damage the structure and degrade your roof.
Lower energy costs
When heat builds up in your attic, you need to have your air conditioning working harder. If your attic is well ventilated, hot air will be removed. The temperature in the attic will be lowered. The ductwork and the air inside are cooler. Cooler air flows through the HVAC, straining your A/C unit.
Longer roof lifespan
A properly ventilated attic ensures that your roof’s shingles are not damaged. Heat in the attic will literally bake the shingles, causing them to age prematurely. Proper ventilation will save you a substantial amount of money that you could have spent in repairs.
The right amount of ventilation
You need to consult a professional regarding your home’s ventilation. Too much ventilation and some roof vents could be potential leakage areas. Too little ventilation is also not good. You need to have just the right amount of ventilation for your home.
An attic fan is a crucial element. Vents do create passive cooling. An attic fan is the most effective cooling method to ensure maximum airflow through the attic. It also removes moisture from the attic. You can opt to install solar attic fans. They qualify for a federal tax credit – 30% of the total cost of installation and purchase. You may need 2 or 3 fans, especially if the house is over 1,600 square feet. Attic fans can actually mean that your bills will go higher, especially if they’re not solar. Note that attic ventilators could suck air from the crawl space into your house. They could also back-draft water heaters and put carbon monoxide into your home. Attic fans may suck conditioned air out of your house, even when they are solar, increasing the bills. For the fan to work, the air must come from the outside. It should not be pulled from the house. Your ceiling needs to be airtight.
All in all
The best thing to do is to ensure that your attic is well balanced in terms of ventilation. The intake vents – which are usually installed in the under-eave, roof’s bottom edge and soffit and exhaust vents, which are usually installed near or at the roof’s peak, should be well balanced. As we have seen, attic fans could be a solution, but only if the attic is airtight. The importance of a well-ventilated attic cannot be underestimated, though.
