As temperatures rise throughout the Chicagoland area, many homeowners notice their second floors becoming warmer, their air conditioning running longer, and their energy bills climbing. In many cases, the culprit isn't the air conditioner—it's excessive heat trapped in the attic.

Your attic plays a critical role in the overall performance of your home, and your roofing system is one of the biggest factors in determining how much heat builds up during the summer months.

How Hot Can An Attic Get?

On a sunny summer day, roof surface temperatures can easily exceed 150°F. Without proper ventilation and airflow, attic temperatures can climb to 130°F–160°F or more.

That trapped heat doesn't stay in the attic. It radiates downward into your living space, forcing your HVAC system to work harder to maintain comfortable indoor temperatures.

The result can be:

  • Higher cooling costs

  • Uneven temperatures throughout the home

  • Increased strain on your air conditioning system

  • Reduced indoor comfort

  • Premature aging of roofing materials


The Role Your Roof Plays in Attic Heat.

Many homeowners think of a roof simply as protection from rain and snow, but a properly designed roofing system does much more.

A high-performing roof helps regulate temperature through:

Proper Ventilation​

One of the most important components of any roofing system is attic ventilation.

Intake vents allow cooler air to enter the attic while exhaust vents allow hot air to escape. This continuous airflow helps prevent heat from becoming trapped beneath the roof deck.

Without adequate ventilation, your attic essentially becomes an oven during the summer.

Quality Roofing Materials

Modern roofing products are designed to reflect more solar energy and withstand extreme temperatures better than older materials.

As shingles age, they can lose some of their effectiveness, making your home more susceptible to heat buildup and energy loss.

Proper Installation

Even the best roofing products can underperform if they are not installed correctly.


Signs Your Roof May Be Contributing to Excessive Attic Heat.

You may want to have your roofing system evaluated if you notice:

  • Upstairs rooms are consistently warmer than the rest of the home

  • High summer energy bills

  • Excessive attic temperatures

  • Your air conditioner runs constantly during hot weather

  • Your roof is approaching 15-20 years old

  • You have never had your attic ventilation assessed

These symptoms often indicate that your roofing system may not be ventilating as effectively as it should.
