Reduce the burden on your AC unit with proper ventilation

AAR Expert Henry Staggs says a well-ventilated attic lowers monthly energy costs and extends the life of your HVAC system.

This month, we turned to our AskARoofer Experts to explore one of the most important — and often overlooked — components of a high-performing roofing system: ventilation. Proper attic ventilation plays a critical role in regulating temperature, improving energy efficiency and protecting the long-term health of both the roof and the home.

To better understand its impact, we asked our Experts to weigh in on the following question: How do ventilation design choices impact attic temperatures, HVAC performance and long-term shingle durability? 

Henry Staggs, founder of The Arizona Roofer, shared his thoughts:

In the Arizona heat, roof surface temperatures can easily exceed 160°F, causing attic spaces to climb well above 140°F. Without proper airflow, that trapped heat eventually "soaks" through your insulation and into your living space. 

A well-ventilated attic creates a thermal buffer, significantly reducing the burden on your AC unit. By allowing your home to "breathe," you aren't just protecting your shingles — you're lowering your monthly energy costs and extending the life of your HVAC system.
