Does My Home Need Roof Ventilation?

Your roof protects your home from harsh weather. But even the strongest shield needs assistance to stay durable. That's where roof ventilation comes into play.

Pennsylvania and New Jersey's top roofing expert discusses whether your home needs roof ventilation and when to carry it out. We'll also describe what it involves and outline the benefits of roof ventilation. 

When should you carry out roof ventilation? 

Roof ventilation is an activity you should carry out year-round to keep the internal temperature constant and maintain the structural integrity of your home. Failure to do this can result in:

Shingle deterioration

Excessive heat weakens the shingles, developing cracks and fragility, ultimately decreasing longevity.

Moisture accumulation

Warm air has a higher capacity to retain moisture, and in poorly ventilated attics, this surplus moisture condenses on cooler surfaces. 

This condensation can foster mold growth, contribute to wood decay, and potentially compromise the structural integrity of the building over time.

Increased energy expenses

With a scorching hot attic, your air conditioning system works overtime to maintain a comfortable indoor temperature, leading to higher energy consumption. 

Adequate ventilation helps regulate the attic's temperature, alleviating the strain on your HVAC system and reducing energy bills.

 Ice dams

In the winter, improper roof ventilation can cause ice dams to form, which damages your gutters and shingles.

Exploring roof ventilation

Understanding roof ventilation involves knowing its two main components: intake and exhaust. 

Soffit vents, typically situated beneath the eaves, play a vital role by allowing cool air to enter the attic space. Once inside, this cool air circulates and exits through exhaust vents commonly located on the roof itself. 

Exhaust vents come in various forms, offering different functionalities:

Ridge vents: Positioned along the roof's peak, ridge vents facilitate a continuous airflow.

Gable vents: Placed near the gable ends of the roof, these vents create triangular-shaped openings to promote ventilation.

The extra benefits of roof ventilation

Apart from reducing energy bills, keeping your attic cool, and preventing moisture problems, roof ventilation offers more advantages:

Reduced ice dam risks

In colder regions, good ventilation helps prevent the formation of ice dams. Ice dams form when warm air from the attic melts snow on the roof, causing water to refreeze at the eaves, which can lead to roof leaks.

Prolonged roof lifespan

Through temperature and moisture control, ventilation extends your roof's life, saving you money by delaying the need for future replacements.

Improved indoor air quality

Proper roof ventilation promotes better indoor air quality by reducing the risk of mold, mildew, and other airborne contaminants. This creates a healthier living environment for you and your family.
