A new roof is a big investment, and having proper roof ventilation is one way to make sure it stays in good condition and protects your home. Here are some things you should know.
Why Ventilation Matters
Good roof ventilation means you have good airflow under the roof and through the attic. This is important for two reasons. First of all, moisture can build up when there’s not good ventilation. This leads to mold and mildew problems that can damage the wood components of your roof and the insulation. Another issue to consider is the buildup of heat in the attic, which raises your energy bills.
Proper roof ventilation varies among roofs. As a rule of thumb, you need one vent for every 150 square feet of attic if there’s no vapor barrier or one for every 300 square feet with a vapor barrier. There are soffit vents, hood vents, ridge vents, and gable vents that work together to move air in and out. Roofers will consider all your roof characteristics to determine what will work best.
Signs of Ventilation Issues
It’s important to recognize signs of poor roof ventilation so it can be addressed. These signs include excess attic moisture or insulation that’s deteriorating. Your shingles may also start to show premature wear. They may buckle, curl, or crack because of trapped moisture and excess heat in the attic.
