The attic may be out of sight, but it shouldn’t be out of mind. Proper ventilation reduces energy costs, prevents mold and mildew growth, extends roof shingle life, minimizes ice dam formation in winter, and enhances indoor air quality. But how do you know when your attic’s ventilation system isn’t working? Here are six red flags that it’s time to call a roofing professional for an attic inspection:
1. A warm, humid attic.
When your attic isn’t properly ventilated, excessive heat rises through the attic and into living spaces below. In addition, moisture accumulates in the attic and causes damage to wood and insulation. Mold and mildew thrive in these conditions, and can spread to walls and ceilings of living spaces below. Peeling paint and blisters are other signs of poor attic ventilation. URL https://www.sprayfoaminsulationphoenix.com/
2. Unexpectedly high utility bills.
An attic with improper ventilation allows heated air to escape, forcing your HVAC system to work harder to maintain comfortable temperatures. Insufficient attic vents or blocked soffit vents also can limit airflow, driving up heating and cooling costs.

3. Frequent ice dams in the winter.
Improper attic ventilation creates warm, moist environments that attract pests like termites and carpenter ants. Poor ventilation also makes it easier for these insects to access attic spaces, especially if the soffit and ridge vents are clogged or damaged. When these insects infest your home, the result can be costly structural damage and extensive repairs. Fortunately, proper attic ventilation minimizes ice dams and other roof water damage by keeping the roof surface cooler and preventing snow melt from reaching the gutters.
