The Importance of Proper Roof Ventilation

Roof ventilation is a vital aspect to any residence or building. Without it, your roof is more prone to leaks, decay in the buildings structure, and heat build-up. Proper ventilation greatly prolongs the life of your roof. The damage caused by poor roof ventilation is often expensive, so it is important to know that your home has a properly working air flow system.

Signs You Need Better Roof Ventilation

• Your ceiling is hot to the touch on a warm sunny day. This is a sign your attic is essentially acting like a solar panel. This will cause unwanted heating of your home and a rise in energy costs
• Any dampness, mold, frost, or leaks in your attic is a sign that warm moist air is condensing and causing excess moisture.
• Peeling paint or decaying of your home’s exterior around your attic
• Uneven frost accumulation on your roof on a cold sunny morning

What You Need to Know

Because roof ventilation is different for every building and roofing system, you need to know what your roof needs. An attic should always be vented, but not every single-ply membrane roof will. Some vent systems are not overly visible, but could be there and functioning properly. Climate should be a factor when deciding what your roof needs, for example, in warmer climates, ice dams may not be an issue. Doing research and talking to your contractor will help you determine what your roof needs.
