Why Is Roofing Ventilation Important

It’s probably not something you think about often but ventilation in your roofing system is important and unique to every home. Factors such as climate and roof/ceiling designs all need to be considered when venting your roof.

Proper ventilation allows for consistent airflow through the underside of your roof which prevents, depending on the season, the buildup of heat, cold, and moisture under your roof.

In winter months, proper ventilation helps maintain a colder roof temperature by exhausting hot air. This is important to prevent melting and refreezing of snow on the roof. When this happens, ice dams are created which can lead to leaks and water damage. In addition, proper ventilation removes moisture and humid air. Lack of ventilation can trap cold air causing moisture buildup, mould and mildew, damaging the roof and even the gutters during ice dams.

In summer, a poorly ventilated roof can result in an extremely hot attic space and moisture build-up which can lead to a variety of problems including warped and damaged shingles. Too much heat over time can also prematurely deteriorate roofing materials.

Not only does a properly ventilated attic extend the life of your roof but it helps reduce energy costs. When the temperature increases outside, a properly vented roof allows heat to escape, thereby reducing the workload on fans and air conditioners used inside. Overall, reducing your energy consumption.

Properly ventilating a roof is vital to protect against the problems caused by seasonal weather patterns. When reroofing your home, it’s the ideal time to ask your roofer to evaluate your ventilation and make sure the proper amount of ventilation is installed.
