When you own a home for the first time, one of the first things you should know about is the importance of roofing ventilation. If your bathroom and other parts of your home aren’t well ventilated, you’ll have a tug-of-war with mold and mildew growth. The same can be said for your roof, as this will cause problems for your home. In this post, the top roof replacement contractor, Innovative Roofing & Siding, shares the key things to know about roof ventilation.

Importance of Roof Ventilation

Many roofing contractors emphasize the importance of air sealing and insulation to improve your home’s energy performance. After all, your home isn’t a vacuum-sealed box that shouldn’t allow anything in. As such, airflow is one of the most important factors of a home, especially in the attic and roofing system. Remember that warm air rises to escape, so with poor insulation and ventilation, you’ll experience uncomfortable heat all-year long.

Poor Ventilation Through the Seasons

During the summer months, your roofing contractor will tell you that heat will build up in the attic, causing the roof deck to overheat, and your ceilings to radiate heat into your living space. Your shingles will age even quickly due to sustained exposure to heat. The sustained heat will cause poor energy efficiency since your HVAC system will have to work harder to sustain comfortable temperatures.

During the winter, warm and moist air will get into your attic. Condensation will follow afterwards which can cause wood rot, as well as mildew and mold growth on the attic insulation. Warm air will also cause snow to refreeze on the roof, causing ice dams.

To prevent these issues, make sure that you get regular roof inspections to see if your roof is well ventilated, and have it treated if there are any issues spotted.
