Metal roofers in Joliet install steel or aluminum panels, and choosing the right one starts with knowing the panel types, the costs and how a metal system handles Illinois weather. This guide covers four widely sold roof panels you will hear contractors mention, plus six Great Roofing services that fit homeowners weighing a roof decision in Joliet and the south Chicagoland area.
A properly engineered and installed metal roof commonly provides a service life of 40 to 60 years, depending on environment and maintenance, according to Metal Construction News. That longevity is the main reason homeowners compare metal against asphalt, and it is why the panel you pick matters as much as the crew that installs it.
What Joliet Homeowners Should Know Before Choosing a Panel
Joliet roofs face freeze-thaw cycles, heavy snow, summer heat and the occasional hail or wind event, so panel gauge, finish and profile all affect how a metal roof performs here.
Keep these factors in mind as you read the list:
- Gauge: a lower number means thicker steel. A 29-gauge panel is sturdier than a 31-gauge panel.
- Coating: galvanized and Galvalume steel resist corrosion differently, and the finish affects how long the color holds.
- Profile: corrugated panels have a classic wavy look, while SM-Rib panels have a flatter, ribbed appearance.
- Pitch and snow: metal sheds snow more readily on roofs with adequate pitch, though snow guards may be needed to control sliding snow above walkways and entries.
- Cost: a 2026 guide reports that metal roofing can cost several times more to install than asphalt, depending on material, roof design and installation requirements.
1. 8 ft. Corrugated Galvanized Steel 31-Gauge Roof Panel (Model 13513)
This Gibraltar Building Products panel is an entry-level corrugated option that suits low-budget projects such as sheds, porch covers and detached garages.
- Specs: 8 ft. length, corrugated galvanized steel, 31 gauge
- Approximate price: $19.98 per panel
- Customer rating: 4.3 out of 5 from 1,216 reviews
- Best suited to: budget-conscious projects where a widely reviewed corrugated panel is the priority
The 31-gauge steel is the thinnest of the four panels in this list, so it fits smaller, low-exposure structures better than a main dwelling roof that takes the brunt of Illinois hail and wind.
Verdict: A well-reviewed, low-cost panel for secondary structures.
2. 12 ft. Corrugated Galvanized Steel 29-Gauge Roof Panel (Model CR12G-U)
This is a longer, thicker corrugated panel from Gibraltar Building Products, and it suits projects that benefit from fewer seams and a sturdier sheet.
- Specs: 12 ft. length, corrugated galvanized steel, 29 gauge
- Approximate price: $42.98 per panel
- Customer rating: 4.5 out of 5 from 113 reviews
- Best suited to: homeowners who want longer corrugated panels and a higher review rating
The extra length means fewer overlaps on a longer roof run, and the heavier 29-gauge steel gives better resistance to denting than the 31-gauge option above. The review count is much smaller, so the rating carries less weight.
Verdict: A step up in thickness and length for larger corrugated installations.
3. 8 ft. SM-Rib Galvalume Steel 29-Gauge Roof/Siding Panel in Black (Model 987646)
This Gibraltar Building Products panel pairs a ribbed profile with a black finish and works on both roofs and siding.
- Specs: 8 ft. length, SM-Rib profile, Galvalume steel, 29 gauge
- Approximate price: $39.98 per panel
- Best suited to: homeowners seeking a black ribbed panel for a roof or siding project
Dark roofs absorb more solar heat, so color choice deserves thought. A 2026 roofing guide notes that cool roofs can reduce cooling costs by 5 to 20%, though that is a general cool-roof estimate and not a guaranteed saving for any one metal roof. A black finish will not behave like a reflective cool-roof coating, which is a fair trade-off for the modern look many homeowners want.
Verdict: A clean, contemporary look in a sturdy gauge, with a roof-and-siding versatility.
4. 12 ft. SM-Rib Galvalume Steel 29-Gauge Roof/Siding Panel in Black (Model 987648)
This is the longer version of the black ribbed panel, built for larger roof planes and wall sections.
- Specs: 12 ft. length, SM-Rib profile, Galvalume steel, 29 gauge
- Approximate price: $54.98 per panel
- Best suited to: homeowners who want a longer black ribbed panel with a strong customer rating
A 12 ft. sheet reduces the number of panels to hang on a steeper or longer roof, which can cut down on seams where water might find a path. As with any metal panel, proper underlayment, fastening and flashing decide how well it keeps water out.
Verdict: The best fit in this group for a larger, modern-looking roof or wall surface.

6. Residential Roof Repair by Great Roofing
Great Roofing's residential roof repair covers leaks, damaged shingles and other roof problems on homes.
It suits homeowners whose roof still has life left but shows a localized problem, such as a leak after a storm or a patch of lifted shingles. Repair is usually the lower-cost first step, and an inspection can show whether the rest of the roof justifies a replacement later. Homeowners can contact the team with questions about the repair before and after the work is done.
Verdict: The sensible choice for a contained problem on an otherwise sound roof.

Panel prices are per sheet, so compare them by coverage as well as sticker price. The 12 ft. corrugated panel costs $42.98, more than twice the $19.98 for the 8 ft. 31-gauge sheet, but it is 4 ft. longer and a heavier 29 gauge. Within the SM-Rib pair, the 12 ft. panel costs $15.00 more than the 8 ft. version, with the same gauge, steel and finish. Panel cost is only one line of a roofing budget, since underlayment, fasteners, flashing and labor all add to the total, which is why a 2026 guide reports metal roofing can cost several times more to install than asphalt, depending on material, roof design and installation requirements. The two services are quoted per home or per job because roof size, pitch and condition drive the price, so use the panel figures to compare materials and request written quotes for the work itself.
How to Vet Metal Roofers in Joliet
The best way to vet metal roofers is to check credentials, ask for a written scope and confirm how the crew handles flashing, underlayment and cleanup, since installation quality drives results as much as the panel.
Ask each contractor these questions:
- Are you licensed and insured for work in Will County and nearby towns?
- What manufacturer certifications do your installers hold?
- How do you handle valleys, penetrations and snow retention?
- What does the warranty cover, and who honors it?
- Can you help with a storm damage insurance claim?

Energy, Recycling and Appearance
Beyond lifespan, metal roofing offers a few benefits worth weighing against its higher upfront cost.
A 2025 guide notes that cool-roof coatings can reflect up to 90% of solar radiation, though actual performance depends on the coating and roof system. That distinction matters in Joliet, where summer cooling loads are real but a dark finish, such as the black SM-Rib panels above, will not reflect like a coating designed for that purpose. The 5 to 20% cooling-cost range for cool roofs is a general estimate, so ask any contractor which finish they are quoting before counting on a specific saving.
Metal systems are also recyclable at the end of their service life, as Metal Construction News reports. That end-of-life question may be decades away, but it means old panels can be recycled rather than sent to a landfill.
Appearance is the third factor. Corrugated panels give a traditional agricultural look, while SM-Rib panels read as flatter and more contemporary, and the finish determines how well that color holds over time. For a consumer-level overview of durability and appearance, Bob Vila’s guide to metal roof benefits is a useful read.
Common Questions About Metal Roofers
Is metal roofing worth the cost in Illinois? It can be, if you plan to stay in the home long enough to benefit from its long service life. The upfront cost is higher than asphalt, so compare quotes for both. Divide each quote by its expected lifespan to see the cost per year of service, and factor in your own timeline in the home.
Will a metal roof be loud in rain or hail? Proper underlayment and decking reduce noise, and installation details matter more than the panel alone. Heavier steel, such as 29 gauge, is generally more resistant to denting than 31 gauge.
Can metal go over existing shingles? Sometimes, depending on local code and roof condition. A contractor should inspect the deck first, looking for moisture damage, soft spots and uneven surfaces that would telegraph through new panels. Great Roofing covers the topic in its page on metal roofs with asphalt shingles.
Will snow slide off a metal roof? On a roof with adequate pitch, metal sheds snow more readily, though snow guards may be needed to control sliding snow above walkways and entries.
Start by photographing your roof's problem areas and writing down its age, then request two written quotes so you can compare materials and scope side by side. Great Roofing can inspect your home, explain whether roof repair or roof replacement makes more sense, and help you request an estimate from a local family-owned contractor.
