Understanding Attic Ventilation: The Foundation of Energy Efficiency
Living in Dover, NH , you understand the importance of maintaining comfortable indoor temperatures year-round. Effective cooling systems play a crucial role in energy efficiency , especially in our local climate conditions .
These systems work by promoting air circulation that expels heated air from your attic space. In hot weather , roof spaces can exceed dangerous levels, which forces your HVAC system to operate less efficiently .
The fundamental principle of attic ventilation involves creating a continuous airflow system that removes hot air from your attic space while drawing in cooler outside air. This process, known as the stack effect, occurs naturally when intake vents (typically located in soffits) allow cool air to enter while exhaust vents (like attic fans or ridge vents) remove heated air. For 03820 residents, this system is particularly important due to our regional climate patterns and seasonal temperature variations.

The Hidden Benefits of Attic Airflow
Beyond energy savings, proper attic ventilation provides critical moisture control that protects your home's structural integrity and prevents costly damage. In NH's climate, temperature differentials between indoor and outdoor air create conditions where moisture can condense in poorly ventilated attics. This moisture leads to mold growth, wood rot, insulation degradation, and potential structural damage that can cost thousands to repair. Industry reports indicate that moisture-related attic damage repairs typically cost $3,000-$8,000, making prevention through proper ventilation a wise investment.
