When getting a new roof, many homeowners will be focused on the roofing system itself. What a lot of people don’t realize is that they also have to pay attention to their attic ventilation and ensure they have a proper one in place if they want to avoid roof repair services. Why is this?
Let’s start the discussion by understanding first how attic ventilation functions.
Attic Ventilation Function
Attic ventilation primarily functions in two ways: lets in cool, fresh air into the attic and allows hot, moist air to escape from the attic. In cold climates, this keeps a roof “cold”, helping prevent snow on the roof from melting and keeping ice dams at bay. In warm climates, it helps get rid of hot air, which promotes moisture problems.
What You Avoid With Proper Attic Ventilation
- Premature Damage to Roofing Materials – When heat accumulates in an attic, it can “bake” shingles from within, causing premature damage which can give rise to a need for early roof replacement.
- Poor Energy Efficiency – When heat builds up in an attic, the thermal transfer occurs, making it difficult for cooling systems to reach desired indoor temperatures. As a result, cooling systems work doubly hard, using more energy than necessary and causing high energy bills.
- Moisture Issues – When there’s too much moisture in an attic, wooden components in the roofing structure start to rot. Additionally, the buildup of moisture leads to mold growth, which can lead to health problems in the long run.
