Have you ever gone up into your attic in the middle of summer and it feels like you’re stepping into a sauna? Chances are, your home doesn’t have a proper roof ventilation system. It may seem like a minor inconvenience – after all, how often are you in your attic? However, homes without roof ventilation may be at higher risk for more significant problems.
What is Roof Ventilation?
Roof ventilation generally uses turbines or vents in the attic and roof to help regulate the temperature in your attic and upper floors.
It’s recommended that houses in the U.S. have at least one square foot of ventilation for every 300 square feet of space in their attics. The goal is to have the temperature in your attic be just a few degrees different than the temperature outside – whether it’s the summer heat or winter cold.
Here are three reasons proper roof ventilation is essential in your home:
1. Roof Ventilation Saves on Energy Costs
Without roof ventilation, your AC system is doing more work than necessary to keep your home cool in the summer.
Of course, you probably aren’t air conditioning your attic. But even with the best insulation, some of that heat will seep into the upper floor (or main floor if you live in a single-level home) – forcing your system to work overtime to handle the extra heat. If your roof has proper ventilation, it should keep temperatures down in the summer and up in the winter.
2. Roof Ventilation Prevents Damage
In the heat of the summer, attics that don’t have roof ventilation can get extremely hot. If that heat has nowhere to go, it basically acts like an oven and bakes your attic.
Not only can this damage anything you’ve stored up there, but it can weaken your shingles or other roofing materials. These scorching temperatures can force you to repair or replace your roof sooner than expected.
3. Roof Ventilation Reduces the Chance of Mold and Mildew
Improper venting also increases the risk of condensation forming in your attic. Mold thrives in dark, humid places, and if you have water in your attic, you may develop a mold infestation.
This issue can quickly become a significant health problem and could force you to spend thousands of dollars in mold removal services and material replacements.
Finding the Roof Ventilation System That’s Right for You
Installing a roof ventilation system might not be cheap. But when you consider the cost of the potential problems that may arise without ventilation – plus the energy savings – your investment might be worth it.
It’s important to remember that every house is different and will have different ventilation needs. Do your homework to determine which type of system will best benefit you.
