Metal Roofing Installation & Repair in Plainfield, IL
Standing Seam, Metal Panels & Chimney Flashing
Metal roofing used to be something you saw on barns and commercial buildings. That's changed significantly over the last decade — and for good reason.
The product has evolved. Modern residential metal roofing systems look nothing like the corrugated panels most people picture. Standing seam profiles, steel shingles, and copper accent details are showing up on high-end homes throughout Naperville, Plainfield, and the surrounding communities — not because it's trendy, but because homeowners who've already replaced one or two asphalt roofs are doing the math and deciding they'd rather pay more once than less twice.
At Plainfield Superior Roofing, we install and repair residential metal roofing systems — including standing seam metal roofing and exposed-fastener metal panels — and we handle chimney flashing repair and replacement, which falls under the sheet metal trade and is one of the most chronically mishandled details on roofs throughout Will County.
If you're evaluating metal roofing as a long-term investment, or you've got a chimney flashing that's been patched with caulk more than once and keeps coming back as a leak, this page covers what you need to know.
Why Metal Roofing Makes Sense
in the Chicago Suburbs
The climate in this part of Illinois is not kind to roofing materials. You get hail in May, ice dams in January, temperature swings of 40 degrees in a single day during spring and fall, and UV exposure all summer that bakes granules off asphalt shingles faster than the warranty assumes.
Metal handles all of it better than asphalt.
Hail that dents or cracks an asphalt shingle will leave a cosmetic dent in a steel panel but won't compromise its waterproofing integrity. Freeze-thaw cycling that works open flashing joints and lifts shingle tabs doesn't affect a standing seam system the same way — the panels are designed to float and contract with temperature changes. And UV exposure that degrades asphalt over 20 years simply doesn't break down painted or Galvalume-coated steel at the same rate.
The result is a roof that carries 40- to 50-year paint warranties from major manufacturers and, in many cases, outlasts the homeowners who install it.
That doesn't mean metal is right for every situation or every budget. We'll walk you through the honest trade-offs before any decision is made.
Metal Roofing Services We Offer
Metal Roof Installation
When homeowners in Plainfield and the surrounding area start asking about metal roofing, the conversation usually begins with one of two scenarios.
The first is a homeowner who's on their second or third asphalt roof and is tired of the cycle. They've replaced shingles after hail events, dealt with leaks around an addition, and watched granules wash into the gutters every spring. They want a long-term solution and they're willing to pay more upfront to get off the replacement treadmill.
The second is a homeowner with a low-slope section — a garage, an addition, a sunroom — where asphalt shingles consistently underperform because the pitch isn't steep enough to shed water reliably before it finds a way under the laps. Metal panels handle low slopes in a way asphalt simply can't match.
Both scenarios are legitimate candidates for metal roofing. What we do before any installation is confirm that metal is actually the right answer for the specific roof in question — because it isn't always.
Metal Roofing System Options
There are two broad categories of residential metal roofing: concealed-fastener systems and exposed-fastener systems. They behave differently, cost differently, and are appropriate for different applications.
Concealed-fastener systems — most commonly standing seam — hide all fasteners beneath the panel surface. The panels interlock at raised seams and are secured to the deck through hidden clips that allow the panel to expand and contract with temperature changes without stressing the fastener points. This is the premium residential option and the one most homeowners are envisioning when they picture a metal roof on a house.
Exposed-fastener systems use screws or nails driven through the panel face into the deck or purlins. The fasteners are sealed with rubber washers. These systems are faster to install and less expensive, but the washers are a long-term maintenance point — they degrade over time and eventually need to be replaced or re-torqued. For certain applications and budgets, this is a reasonable choice. For a primary residential roof where the owner wants to be done with roofing decisions for 40 years, we generally steer toward a concealed-fastener system.
Steel and Aluminum
Most residential metal roofing in the Midwest is steel — either Galvalume (zinc-aluminum coated) or painted Galvalume — because it's strong, cost-effective, and widely available in a range of profiles and colors. Aluminum is a step up in corrosion resistance and lighter in weight but carries a higher material cost and is softer, which means it dents more easily from hail impact. For homes more than a few miles from the ocean, steel is almost always the right call.
What full metal roof installation includes:
- Roof inspection and substrate evaluation
- Tear-off of existing material and disposal
- Decking repair or replacement as needed
- Installation of appropriate underlayment — a critical detail on metal roofs where condensation management matters
- Panel installation per manufacturer specifications
- Custom-formed trim, ridge, hip, and eave details
- Flashing integration at all penetrations, walls, and transitions
- Full cleanup

Standing Seam Metal Roofing
Standing seam is the system we install most often for residential metal roofing projects in the Plainfield area — and it's the product that's driven most of the residential metal roofing growth over the last ten years.
The profile is clean. Two panels interlock at a raised seam — typically 1.5 to 2 inches tall — that runs vertically down the slope. No exposed fasteners, no visible screws, no rubber washers to maintain. The panels are secured through hidden clips that are engineered to allow thermal movement. Steel expands and contracts — a 16-foot panel might move a quarter inch between a cold January night and a hot August afternoon — and the clip system accommodates that movement without cracking seams or backing out fasteners.
That's not just an engineering footnote. It's the reason standing seam roofs perform at 40 years in conditions that would have compromised an exposed-fastener system at 20.
Two production methods: roll-formed on-site vs. factory panels
Standing seam panels can be roll-formed on the job site from a coil of flat steel using a portable panel machine, or they can be ordered as pre-cut factory panels. Job-site roll-forming allows panels to run the full length of the slope in a single continuous piece — no horizontal seams, which eliminates one of the most common water entry risks.
Factory panels are typically used for shorter runs, complex rooflines, or when job-site access limits equipment placement.
We use continuous-run job-site panel fabrication wherever the roof geometry allows it.
Realistic expectations on cost
A standing seam metal roof will cost more than a premium architectural shingle roof. On a typical single-family home in the Plainfield area, the installed cost for a standing seam system runs roughly two to three times the cost of an architectural shingle replacement.
That sounds like a lot until you consider that a quality asphalt roof may need to be replaced once or twice more in the same timeframe a standing seam system will serve. The long-term math favors metal for homeowners planning to stay in their homes for 15 or more years.
Standing seam highlights
- Concealed clip fastening system for thermal movement accommodation
- Panels run full slope length wherever possible — no horizontal seams
- 40-year and 50-year paint warranties available on select steel products
- Class 4 impact resistance ratings on most steel products
- Available in a wide range of profiles and colors
- Suitable for slopes as low as 1:12 with appropriate underlayment
A standing seam project worth mentioning
A homeowner in a Plainfield subdivision off Route 30 had been through two asphalt roofs on the lower-slope sections of her home — a rear family room addition and the garage — in less than 20 years. Neither failed catastrophically, but both started leaking within 12 to 15 years. The pitch on those sections was around 2:12, which is technically within the manufacturer's specification for most shingles but at the low end where water moves slowly and margin for installation error is thin.
We installed a standing seam system on those sections using 24-gauge Galvalume steel panels in a dark bronze finish that complemented her existing architectural shingles on the steeper main roof slopes. Three years in and there hasn't been a single service call. She's done with that part of the roof.
That hybrid approach — metal where the geometry demands it, shingles on the steeper sections — is something we see increasingly in this area and it's often the most cost-effective long-term solution for homes with mixed slope profiles.

Chimney Flashing Repair
Chimney flashing is the single most common source of chronic roof leaks on residential homes in the Plainfield area. Bar none.
It's a sheet metal specialty — which is why it lives in this service category rather than with general shingle repairs — and it requires a different skill set than shingle installation. Chimney flashing is a custom-fabricated assembly that has to accommodate two completely different materials that move independently of each other: a masonry chimney that expands and contracts with temperature on its own schedule, and a roof deck that does the same thing on a different schedule. The flashing system has to bridge that gap without cracking, separating, or allowing water behind it.
When it's done right, a properly installed chimney flashing system should last 20 to 30 years. When it's done wrong — or when a previous contractor decided that a tube of caulk was a reasonable substitute for actual sheet metal work — it leaks, and it keeps leaking until the flashing is properly replaced.
How chimney flashing is supposed to work
A correct chimney flashing assembly has two components working together.
The base flashing (also called step flashing or apron flashing) is integrated into the roof surface at the sides and front of the chimney. It directs water that runs down the chimney face out onto the roof surface rather than behind the roofing material.
The counter flashing (also called cap flashing) is embedded into the mortar joints of the chimney itself and laps over the top of the base flashing. This is the piece that seals the joint between the masonry and the roof. Because the counter flashing is attached to the chimney and the base flashing is attached to the roof, the two pieces can move independently without breaking the seal between them.
When someone fills that joint with caulk instead, the caulk bonds both sides together. It holds fine for a year or two — maybe three — and then one of them moves and the caulk cracks. Water gets in. The homeowner calls a roofer. Another roofer adds more caulk over the cracked caulk. It fails again. This cycle repeats until someone replaces the flashing correctly.
We see this on probably half the chimney inspections we do throughout Will County.
What bad chimney flashing actually costs you
A homeowner in Bolingbrook called us after noticing a stain on the ceiling of his main floor bedroom — directly below the chimney stack on his second floor. He'd had the flashing "repaired" twice in three years by two different contractors. Both times, the fix was caulk.
When we opened it up, the counter flashing had separated from the chimney entirely on the back (downslope) side — the most critical section, where water running off the back of the chimney concentrates. Water had been running behind the base flashing and directly onto the sheathing for at least two winters. We found soft sheathing on two panels near the chimney base and early staining on the top plate of the interior wall below.
The flashing replacement itself was a half-day job. The collateral damage — sheathing replacement, interior drywall repair, and paint — added several thousand dollars to the total project cost. All of it preventable with a proper flashing installation the first time.
What proper chimney flashing repair includes:
- Full removal of existing failed flashing assembly
- Cleaning and preparation of mortar joints for counter flashing embedment
- Custom fabrication of base and counter flashing components to fit the specific chimney dimensions
- Step flashing integration along the chimney sides, laced with shingles
- Saddle or cricket installation behind wide chimneys (this is a critical detail that gets skipped frequently — a chimney wider than 30 inches should have a cricket behind it to divert water around the chimney rather than letting it pool against the back face)
- Counter flashing set into cleaned mortar joints and sealed with an appropriate polyurethane sealant — not general-purpose caulk
- Final inspection and water test
On chimney saddles and crickets
If your chimney is wider than 30 inches measured perpendicular to the slope, building code in most Illinois jurisdictions requires a saddle — a small peaked structure installed on the upslope side of the chimney to divert water around it. A lot of older homes in Plainfield, Joliet, and the surrounding area were built without them, and we find concentrated water damage on the back side of chimneys that have been collecting runoff for decades.
If your chimney doesn't have a cricket and you're dealing with recurring flashing issues or interior staining near the chimney, adding one as part of the flashing repair is something we'll recommend and explain.

Metal Roof Frequently Asked Questions
How much does a standing seam metal roof cost in Plainfield, IL?
For a typical single-family home in the Plainfield area, installed standing seam metal roofing generally runs between $18,000 and $40,000 depending on roof size, pitch complexity, panel gauge, and finish. That's a wide range because the variables matter significantly. An accurate number requires a site visit and measurement. We provide itemized estimates so you can see exactly what's driving the cost.
How long does a metal roof last?
A quality 24-gauge steel standing seam system with a high-durability paint finish carries a 40- to 50-year paint warranty from major manufacturers. The structural lifespan of the system — assuming proper installation and no catastrophic physical damage — often exceeds 50 years. The fastener system, trim components, and flashing details are typically the items that need attention before the panels themselves require replacement.
Will metal roofing be noisy during rain or hail?
On a residential installation where the metal panels are installed over solid decking with an appropriate underlayment between the panel and the deck, noise is minimal — comparable to an asphalt shingle roof. The "tin roof in a rainstorm" sound is associated with metal panels installed over open purlins with an air gap and no insulation beneath them, which is common on agricultural buildings but not on residential installations.
Can a metal roof be installed over existing shingles?
In many cases, yes. An overlay installation — metal panels installed directly over one existing layer of asphalt shingles — is permitted by building code in most Illinois jurisdictions and can reduce installation cost by eliminating the tear-off. There are conditions: the existing shingles should be lying flat without severe cupping or buckling, and the decking beneath should be solid without soft spots. We inspect the existing roof before recommending an overlay and we'll tell you if a tear-off is the better approach.
Does a metal roof increase home value?
According to Remodeling Magazine's Cost vs. Value data, metal roofing consistently recovers a strong percentage of its cost at resale — often in the range of 50 to 70 percent nationally, with variation by market. Beyond the numbers, a standing seam metal roof is a clear differentiator when selling a home in a market where most houses have aging asphalt roofs. Buyers who understand what they're looking at see it as a capital expenditure they don't have to make.
Is metal roofing a good choice for low-slope sections?
Yes — and in many cases it's the best choice. Asphalt shingles are designed for minimum slopes of 2:12 to 4:12 depending on the product and installation method, and they perform better at the higher end of that range. Standing seam metal can be installed on slopes as low as 1:12 with appropriate underlayment and panel selection. If you have a section of your roof that has consistently leaked or needed early replacement, low slope is often the root cause — and metal is the solution worth evaluating.
Why does my chimney keep leaking even after it was repaired?
Almost always because the repair was caulk-based rather than a proper sheet metal flashing replacement. Caulk doesn't permanently bond masonry to roofing material through Chicago-area temperature cycles. It cracks, water gets in, and the cycle repeats. A proper repair requires removing the old flashing assembly and installing a correctly fabricated base and counter flashing system where each component is independently attached — one to the chimney, one to the roof — so they can move without breaking the seal between them.
What is a chimney cricket and do I need one?
A cricket — also called a saddle — is a small peaked structure installed behind the chimney on the upslope side. It's designed to divert water and debris around the chimney rather than letting it accumulate against the back face where it can infiltrate the flashing joint. Most building codes require a cricket on chimneys wider than 30 inches. Many older homes in the Plainfield area were built without them. If you have a wide chimney and recurring leaks on the interior wall below it, the absence of a cricket is often contributing to the problem.
What gauge steel is best for residential metal roofing?
24-gauge steel is the standard we recommend for residential standing seam installations. It's substantially heavier than the 26- and 29-gauge products commonly used in agricultural and light commercial applications, which gives it better dent resistance from hail and foot traffic and a more rigid feel overall. Some budget metal roofing products are offered in 26-gauge — they're technically functional but noticeably thinner and more susceptible to oil-canning (the visible waviness in the panel field that affects appearance).
How do I know if my flashing is the source of my leak?
Chimney and wall flashings are involved in a disproportionate share of residential roof leaks relative to how much of the roof surface they cover. If your leak appears near or below a chimney, a dormer, a skylight, or any point where a vertical surface meets the roof, flashing is the first place to look. Interior staining that follows the wall line rather than spreading across the ceiling is another indicator that water is entering at a vertical transition rather than through the field of the roof.
