As late-summer temperatures climb in Joliet, your roof takes a serious beating. From relentless UV exposure to attic heat buildup, the end of summer brings unique challenges that can reduce the performance and lifespan of even the most durable roofing systems. That’s why this season is the perfect time to apply expert late summer roofing tips, explore asphalt roof cooling tips, and invest in heat-resistant shingles Joliet homeowners can count on for long-term protection.
At Great Roofing, we understand how intense Illinois summers can be. The good news? You can take simple, effective steps to improve your roof’s heat resistance, reduce attic temperatures, and protect your home from the costly effects of thermal stress—all while making your home more energy efficient.
Why Late-Summer Heat Is So Hard on Joliet Roofs
The Roof-Top Hot Zone
Roofing systems absorb a significant amount of solar heat during the day, especially those with darker materials or poor ventilation. On a hot August afternoon in Joliet, surface temperatures on an asphalt roof can exceed 150°F. That much heat doesn’t just stress your shingles—it can raise attic temperatures, damage decking, and cause your HVAC system to work overtime.
Thermal Expansion and Roofing Materials
Heat causes roofing materials to expand. Over time, this leads to:
- Shingle curling or cracking
- Flashing loosening
- Warped decking
- Increased likelihood of leaks after storms
These issues often become visible after a long summer, especially if your roof is nearing the end of its lifespan.
Late Summer Roofing Tips for Homeowners in Joliet
Late summer isn’t too late to take action. In fact, it’s the ideal time to assess your roof’s condition and apply cooling solutions before fall storms and winter snow arrive.
1. Inspect for Heat Damage
A proper inspection can uncover signs of thermal wear that might go unnoticed. Look for:
- Discolored or faded shingles
- Granule loss on asphalt shingles
- Shingles that are brittle or lifting
- Sagging in the roofline
If you’re unsure, a professional inspection by Great Roofing can provide a full assessment and recommend the best next steps.
2. Improve Ventilation
Attic ventilation is key in controlling roof temperature. Without it, heat gets trapped, causing insulation to degrade and shingles to overheat.
We recommend:
- Ridge vents or soffit vents to create airflow
- Powered attic fans for homes with limited passive ventilation
- Clearing blockages in existing vents
The U.S. Department of Energy notes that proper attic ventilation can reduce cooling costs and extend the life of your roof. Learn more from their official energy efficiency guide.
3. Add Reflective Roofing Materials
Adding cool roofing features or replacing aged shingles with heat-resistant shingles Joliet homeowners trust can help reflect solar energy and reduce surface temperatures. Cool-roof-rated shingles are designed with reflective granules that help maintain lower roof temps.
This change:
- Keeps attic spaces cooler
- Reduces the need for A/C
- Extends shingle lifespan by limiting heat degradation

Asphalt Roof Cooling Tips to Beat the Heat
Asphalt shingles are among the most common roofing materials in Joliet. While durable and cost-effective, they can absorb more heat than other options. That’s why these asphalt roof cooling tips are essential.
Choose Light-Colored Shingles
Shingle color plays a major role in temperature regulation. Dark shingles absorb more solar heat, while lighter shades reflect sunlight. Choosing tan, light gray, or pale green shingles can lower your roof’s surface temperature significantly.
Install a Radiant Barrier
Radiant barriers are reflective materials installed in your attic to block radiant heat from entering your living space. While not a replacement for insulation or ventilation, they work well in tandem to keep things cooler inside.
According to research from Oak Ridge National Laboratory, radiant barriers can reduce attic heat gain by up to 10%, lowering cooling costs and roof stress. Learn more about the science here.
Apply a Reflective Roof Coating
For homes with flat or low-slope roofing systems, reflective coatings can drastically reduce surface heat absorption. These coatings are applied directly to the roof and are especially useful for older asphalt roofs needing extra protection.
Why Heat-Resistant Shingles Matter in Joliet
Choosing heat-resistant shingles Joliet homeowners trust is a smart investment that offers year-round benefits. These shingles are designed with high solar reflectance, infrared blocking properties, and enhanced durability to withstand thermal expansion and contraction.
Benefits of Heat-Resistant Shingles
- Lower roof temperatures by up to 50°F
- Reduce attic heat gain
- Minimize UV degradation
- Help qualify for energy efficiency incentives
- Support longer material warranties
Great Roofing works with trusted manufacturers that produce shingles specifically engineered for high-heat performance.
Should You Replace Your Roof Before Fall?
Late summer is a great time to evaluate whether your roof can handle another Illinois winter. If your roof is more than 15 years old or showing signs of wear, it may be time to replace your roof.
Key indicators:
- Repeated leaks or water stains
- Curling shingles across the roof
- Multiple missing shingles or visible bald spots
- Daylight visible through attic boards
- Sagging areas or soft spots on the roof deck
Great Roofing offers full tear-off and replacement services, and we’ll help you select heat-resistant shingles Joliet residents can rely on for strength and performance.
