• Moisture Control: Ventilation helps to prevent moisture buildup in the attic, which can lead to mold, mildew, and rot. Moisture can enter the attic through various sources such as condensation, leaks, or improperly vented appliances.

• Temperature Regulation: Proper ventilation is crucial in hot climates as it helps to eliminate excess heat from the attic, which can decrease the strain on air conditioning systems. This, in turn, helps to maintain a comfortable indoor temperature. Similarly, in colder climates, ventilation can prevent ice dams from forming on the roof by maintaining a consistent temperature.

• Energy Efficiency: A building's overall energy efficiency can be improved by adequate attic ventilation, which reduces the workload on heating and cooling systems. By allowing hot air to escape in the summer and preventing heat loss in the winter, ventilation helps to create a more stable indoor environment.

• Roof Longevity: Proper ventilation can extend the lifespan of the roofing materials by reducing the likelihood of damage caused by excessive heat or moisture buildup. It can also help prevent premature deterioration of the roof structure.

Fact! All major shingle manufacturers will void their shingle warranties if their shingles are installed over improperly ventilated attics.
