How Each Material Stands Up to Midwest Heat, Storms, and Humidity
Illinois summers bring more than long days and green lawns—they also bring intense heat, high humidity, and unpredictable storms. For homeowners across Central Illinois, choosing the right roof can make a big difference in comfort, efficiency, and long-term performance. If you’re comparing metal vs asphalt roofing, it’s important to understand how each system handles the challenges unique to our region.
At Whitney Roofing, we’ve installed hundreds of roofing systems throughout Effingham, Mattoon, Charleston, and beyond. In this blog, we’ll break down the strengths and drawbacks of both metal and asphalt roofing so you can make an informed decision tailored to Illinois summers and beyond.
Comparing Metal vs Asphalt Roofing in Central Illinois
Both metal and asphalt roofing are popular choices in Illinois—but they perform very differently. Let’s take a closer look at the features that matter most during the summer months.
Heat Resistance and Solar Reflectivity
Illinois summers often come with stretches of 90+ degree days and intense sunshine. One of the biggest concerns for homeowners is how well a roof reflects heat and keeps the attic space cooler.
- Metal Roofing: Metal panels are highly reflective and can reduce surface temperatures significantly. Many systems include “cool roof” coatings that reflect solar radiation instead of absorbing it. This leads to lower attic temps and less strain on your air conditioning system.
- Asphalt Shingles: Standard asphalt shingles tend to absorb heat, which can raise attic temperatures and increase cooling costs. Lighter-colored shingles can help, but even then, their reflectivity is far lower than metal.
According to the U.S. Department of Energy, cool roofing materials like metal can reduce peak cooling demand by 10–15%. That’s a major win during Illinois’ hottest months.

Durability in Storm Conditions
Illinois summers can bring more than heat—they also deliver high winds, heavy rain, and hail. How do metal vs asphalt roofing systems hold up?
Wind and Impact Resistance
- Metal Roofing: Standing seam and interlocking metal panels are designed to resist high winds, with many rated for gusts up to 140 mph. Metal also resists cracking, warping, and flying debris, making it an excellent choice in storm-prone areas.
- Asphalt Shingles: While many architectural shingles are rated for strong wind resistance, they can still lift or tear under extreme conditions. Impact-resistant shingles are available, but they may not perform as well over time compared to thicker, more rigid metal panels.
The Insurance Institute for Business & Home Safety (IBHS) ranks metal among the most resilient materials in high-risk weather regions.

Installation Time and Upfront Cost
For many homeowners, cost is a big part of the roofing decision—and asphalt shingles often win in this category.
Cost and Project Timelines
- Asphalt Roofing: Asphalt shingles are one of the most budget-friendly roofing options. Installation is quicker and more widely available from general roofing crews. This can be helpful if you’re replacing your roof on short notice.
- Metal Roofing: Metal comes at a higher upfront cost—usually 2 to 3 times more than asphalt shingles. It also requires specialized installation skills and more time on site. However, the investment may pay off in lower energy bills and longer lifespan.

Lifespan and Maintenance
Your roof is a long-term investment, so durability and required maintenance are important to consider.
Longevity and Upkeep
- Metal Roofing: Metal systems can last 40–70 years with minimal maintenance. Occasional checks for screws, seams, or surface wear are all that’s needed. They’re also fire-resistant and non-combustible.
- Asphalt Roofing: Standard asphalt roofs typically last 20–25 years, depending on materials and installation quality. They may require periodic repairs, especially after heavy storms or hail.
Metal’s lower maintenance and long service life make it ideal for homeowners who want long-term peace of mind.

Aesthetic Options and Curb Appeal
Both metal and asphalt come in a variety of styles—but which offers more visual versatility?
Style and Customization
- Asphalt Roofing: Today’s shingles come in a wide array of colors, patterns, and profiles. Architectural shingles offer layered depth and textures that suit most traditional homes in Illinois.
- Metal Roofing: While some associate metal with industrial buildings or barns, modern options include metal shingles, shakes, and standing seam panels in many finishes. These can offer sleek, modern, or even historic looks depending on the style you choose.
Both materials provide strong curb appeal—but metal adds a more modern or premium edge.

How Metal vs Asphalt Roofing Performs Over Time in Illinois Summers
Summers in Central Illinois are hard on materials. Sun exposure, UV rays, and humidity all take their toll. Here’s how each roofing type holds up in the long run.
UV and Weather Resistance
- Metal Roofing: Powder-coated finishes protect against fading, corrosion, and chalking. This keeps metal roofs looking sharp even after decades of exposure to sun and moisture.
- Asphalt Shingles: UV can dry out and degrade shingles over time, leading to cracking, curling, and granule loss. This shortens their life span, especially if attic ventilation is poor.
If you’re planning to stay in your home long-term, metal will require fewer replacements and repairs across decades.

Which Roof Is Right for You?
Choosing between metal vs asphalt roofing really comes down to your priorities as a homeowner. Here’s a quick comparison:
| Feature | Metal Roofing | Asphalt Shingles |
| Reflects Heat | ✅ | ❌ |
| Resists Wind and Hail | ✅ | ⚠️ |
| Lower Upfront Cost | ❌ | ✅ |
| Faster Installation | ❌ | ✅ |
| Longer Lifespan | ✅ | ❌ |
| Low Maintenance | ✅ | ⚠️ |
| Design Versatility | ✅ | ✅ |
If you’re focused on short-term affordability and traditional styling, asphalt may be the right fit. If you’re thinking long-term value, energy savings, and durability through tough summers, metal roofing is likely the better investment.
