Improper roof and attic ventilation are common underlying causes of roof failure. Your roof is always exposed to the worst forces of nature, so having the right ventilation can have positive effects on the lifespan of your roof, including greater comfort, fewer repairs and lower heating and cooling costs.
Here are some of the most certain signs you need better roofing ventilation.
Most homes have insulation, either under the roof decking or on the attic’s floor. Poor ventilation causes the absorbent insulation to soak up and trap moisture. Wet attic insulation loses its effectiveness increasing your household heating and cooling bills.
Quality roof shingles should last decades, but poor ventilation causes early damage. Buckling, cracking or warping shingles are a sign of a very high roof surface temperature. It is often caused by trapped moisture beneath the shingles. Adequate ventilation will protect shingles and avoid costly roof repair projects.
Rusting of Metal Fasteners
Rusting of the fasteners in your attic is a sign of moisture problems caused by poor ventilation. Roofing straps, HVAC components and electrical system components should be completely rust-free. Even mild-to-moderate surface rust on those components is a sign of improper ventilation.
Excessive Attic Moisture
A well-ventilated attic is a dry environment. Warm, moist air from household activities rises into the attic of your home. Proper attic ventilation pushes that moist air outside. Otherwise, that air gets trapped creating the perfect environment for mold and mildew. Ice dams and icicles forming on your roof and gutters are a sign of cold air trapped in your attic. Your gutters may also need a proper gutter installation.
