Giving your roof space to breathe

By Patrick Cochran and Matt Landry, Red Dog’s Roofing. 

Ventilation is key to keeping your roof healthy and performing efficiently. 

While we might imagine one structure when we think about our roof, it’s actually made up of a range of different parts and sub-systems. From the eaves to the decking to the shingles and beyond, all of these different products and materials affect how the roof and your home perform long term.  

For example, if you want to make sure that your space stays energy efficient and protected for as long as possible, you need to pay attention to the ventilation system beneath your roof. The team here at Red Dog’s Roofing has seen firsthand how this silent issue can cause premature roof failure. That’s why we’re sharing this article, which covers why ventilation matters so much to your roof.  

Heat buildup 

Without a well-designed system of intake and exhaust vents (such as soffit vents at the eaves and ridge vents at the peak), your attic becomes a heat trap. During Florida’s long summer months, this trapped heat can cause the roof to "bake" from the inside out, stressing your shingles, warping materials and increasing your cooling bills as your AC works overtime. 

Moisture accumulation 

Everyday activities like cooking, bathing and even breathing add moisture to your home. Without proper ventilation, that warm, moist air rises and settles in your attic. Over time, this leads to mold growth, dry rot and damage to your roof’s structural components, including the sheathing and plywood. Moisture is one of the biggest threats to roof integrity, and it’s often invisible until significant damage is done. 

Granule loss 

Shingle granules protect your roof from UV rays and physical wear. When attic temperatures soar and humidity levels rise, shingles age faster and begin to lose these granules prematurely. This results in a shorter roof lifespan and a greater likelihood of leaks and deterioration. 

Common ventilation issues 

• Insufficient soffit or ridge vents: A lack of balance between intake and exhaust ventilation reduces airflow and traps heat and moisture. 
• Broken or disconnected ductwork: Vents from kitchen hoods or bathroom fans sometimes dump moisture directly into the attic instead of outside, creating the perfect breeding ground for mold and mildew. 
• Lack of professional oversight: DIY roofing projects or unqualified installations often miss key ventilation requirements, putting your entire roofing system at risk. 

Proper attic ventilation isn’t just about roof health; it’s about whole-home efficiency and long-term savings.
