About Pillar Roofing

Testing How Well Your Attic Breathes

Proper attic ventilation depends on a balanced flow of fresh air entering through the soffits and warm, moisture-laden air escaping through the roof’s exhaust vents.

Your Pillar Roofing Concierge uses controlled diagnostic smoke to reveal the direction and strength of airflow, while infrared temperature readings identify heat buildup and poorly ventilated areas.

These tests show whether existing vents are working correctly, obstructed, or simply inadequate for the size and design of the attic. With real data instead of guesswork, we can recommend the appropriate remedy—whether that means clearing restricted intake vents, improving the ventilation balance, or adding a more proactive exhaust solution.

Fight Texas attic heat-gain

About Pillar Roofing

Fight Texas attic heat-gain

Dynamics of Heat Gain in Your Attic:
Texas attics can exceed 140°F. Passive vents release some heat, but trapped hot air radiates in every direction, heating the insulation and increasing the workload on your A/C.

What the Builders Installed:
Builder-installed vents rely on hot air rising. This passive ventilation does not begin working effectively until heat has already built up and expanded throughout the attic.

Solar Attic Fans & Temperature Inversion:
Cooler, moisture-heavy air settles into the attic overnight and heats rapidly the next morning. This cycle increases indoor heat and can contribute to mold and mildew. Solar attic fans proactively address both problems.

Why & How Solar Attic Fans Work:
Solar attic fans begin working with the morning sun, exhausting trapped air and drawing in cooler outside air before heat accumulates. A cooler attic means less heat enters the home and less strain is placed on the A/C.

About Pillar Roofing

Built for Long-Term Performance

Depending on the manufacturer and model, the solar panel may carry a 20- to 25-year limited warranty, while the motor is often covered for five years.

A quality brushless Pittman motor is engineered for demanding, continuous service and may continue operating well beyond its written warranty when properly installed and ventilated.

Warranty coverage and expected service life are not the same—the warranty establishes the manufacturer’s obligation, while the motor’s actual lifespan can be considerably longer.

Published warranties also vary widely—one model lists 20 years on the panel and housing with five years on the motor, while others provide 10 or 15 years on all major components.
