Inadequate Ventilation vs. Over-Ventilation: Finding Balance

Ventilation is a vital part of your roofing system and your home. It’s important to supply your roof space with adequate air circulation so it doesn’t overheat and cause problems with other roofing materials, stops snow from melting and creating ice dams, and prevents moisture from building up. So, what’s the right amount of ventilation? Let’s take a look at inadequate ventilation vs over-ventilation.

Finding the Best Ventilation Balance for your Roof

The roofing ventilation balance in your home is essential to avoid problems arising in your home.

1. Ice Build-Up Without good ventilation, snow can melt and freeze repeatedly as heat builds up under your roofing structure and in the home. This can cause moisture to form and move under shingles, eaves, and gutters. If you notice icicles hanging from your roof, it means you could have ice build up on your roof.
2. Moisture Condensation As a home is lived in, moisture is released inside. It can accumulate anywhere. Some moisture will rise to the attic or ceilings under the roof and it can begin to cause problems if there isn’t ventilation to relieve it.
3. Mold This rise in moisture and moisture accumulation under a roofing system can lead to unsightly and unhealthy mold and mildew growth. Balanced roof ventilation can help alleviate this.
4. Heat Warmth in a home’s living area will rise wherever it can. As it works its way to the top level of a home, if there isn’t proper ventilation it can eventually pose problems in the attic and roofing space. The heat will rise to an area that is cooler and cause condensation that can accumulate on the wood, metal, and insulation materials of the roofing structure. Eventually, this can deteriorate the integrity and stability of a roof.
5. Summer Weather The higher temperatures need to escape a home’s roofing area or it will collect in the attic space and under the top ceilings, making cooling the home more difficult. A/C costs can rise and make the living situation unpleasant.

While roofing ventilation is a well-planned system for the structure, overdoing it can also cause problems. More doesn’t always equal better. Balancing the ventilation is essential to providing good airflow. In fact, too much ventilation will actually work against this process.

1. Codes Local building codes have been laid out to guide proper ventilation installation materials and methods. They take into account the minimum requirements to provide good ventilation in a certain location while considering common conditions.
2. Expense There is no reason to over-ventilate a roof. Use local building codes and manufacturers’ instructions to decide what is best, and consult with your favorite roofer. Ventilation can be installed in a new or existing roof to provide more adequate ventilation as needed.
3. Heating and Cooling Balanced roofing ventilation is just that, not too much and not too little to produce the right amount of airflow in your attic space. This allows for excess warm air to escape and avoid any type of moisture build-up.

How Do I Know if my Roof has the Right Amount of Ventilation?

If you are noticing condensation problems, high heating or cooling bills, ice accumulation, or other damage to your roof, the ventilation might be the culprit. Roof ventilation is a fine balance that has been developed and adjusted over the years with new technologies.

If you have an older roof, you will likely have an older ventilation layout and design. A roofing expert can advise you on whether it should be adjusted or even increased for your specific roof, home, and location.
