Leaders Roofing has served Wheaton homeowners, churches, and commercial property owners since 1996. DuPage County's seat is one of the region's most established communities — and its housing and institutional stock reflects that history in every roofline.
Wheaton is DuPage County's seat and one of its most established cities — a community where Victorian-era homes near the historic downtown share streets with mid-century ranches, 1970s split-levels, and the newer subdivisions that filled in the northern and western edges of the city through the 1990s and 2000s. That layered housing history means a roofing contractor working in Wheaton needs to be equally comfortable on a 100-year-old home with board sheathing and a steep-pitch gable as on a 1995 two-story with standard plywood decking and a simple hip roof.
What also sets Wheaton apart is its density of institutional buildings. Wheaton has more churches per capita than most DuPage County communities, and Wheaton College adds a significant cluster of institutional structures to the inventory. These buildings — large-span steep-slope roofs, complex hip and valley configurations, significant ridge heights — require experience and logistical capability that not every roofing contractor can provide.
Leaders Roofing Corp was founded in 1996 by Jan Koszyk. We hold an Illinois Roofing Unlimited License (#104.010248), carry full general liability and workers' compensation coverage, and serve both residential and commercial customers throughout Wheaton and the surrounding DuPage County area. Our crew is local, accountable, and experienced on the full range of roofing challenges Wheaton's housing and institutional stock presents.
Wheaton's residential replacement market reflects its layered growth history. Homes near downtown Wheaton — particularly the neighborhoods within a mile or two of the Metra station — date from the early 1900s through the 1960s, and many of those original roofing systems have already been replaced once or twice. The current replacement cycle on those properties often involves working with older decking, original masonry chimneys that need flashing attention, and architectural styles (Colonials, Tudors, Craftsmen bungalows) where material choice and detail matter more than on newer construction.
The Danada area and the subdivisions in northwest Wheaton represent a different chapter — 1980s and 1990s construction that's now 30 to 40 years old and entering first-replacement territory. This is a large portion of Wheaton's total housing stock, and a significant portion of it is past the realistic working life of its original shingles, particularly on homes where attic ventilation was not optimized at installation. Poor ventilation shortens shingle life from the inside out — heat buildup cooks the mat and accelerates granule loss.
For a typical Wheaton home, a full roof replacement runs $15,000 to $45,000. Simpler ranches and two-stories in Arrowhead, Briarcliffe, and similar subdivisions typically fall in the $15,000–$26,000 range. Larger homes with more complex rooflines — multiple dormers, steeper pitches, masonry chimneys, skylights — land proportionally higher. Homes near downtown that may require board-sheathing assessment and replacement will have a variable cost on the deck side that we can only determine after inspection.
Our process: full tear-off, deck inspection and repair of any deteriorated sheathing, ice-and-water barrier at eaves and valleys, synthetic underlayment on the field, new shingles and ridge cap, and proper flashing at all penetrations and transitions. We use GAF, Owens Corning, and CertainTeed systems — all with manufacturer warranties — and back our work with an additional workmanship warranty.
Wheaton has an unusually high concentration of churches, religious organizations, and faith-based institutions — a characteristic that makes it distinct from most DuPage County communities. Wheaton College and the many denominations that have historically chosen Wheaton as a home base have resulted in a significant inventory of institutional buildings, many with large-span steep-slope roofs, complex architectural forms, and the logistical challenges that come with occupied facilities.
Institutional roofing on a church building differs from residential work in several important ways. The roof planes are larger — more squares of material, more linear feet of ridge and hip, more valleys to detail properly. The ridge heights are greater, requiring more rigging and safety planning. Scheduling must account for services, programming, and access constraints that don't exist on a residential project. And the aesthetic requirements are often more demanding — matching existing material profiles or meeting architectural standards set by the congregation or a historic preservation consideration.
Leaders has handled institutional roofing projects in the Chicago suburbs, including work on church structures in DuPage County. Our portfolio includes St. Mark's Lutheran Church — a steep-slope institutional project requiring the kind of crew management and attention to detail that a religious facility demands. If your Wheaton church or institutional building needs a roofing evaluation, we'll provide an honest assessment of its condition and a detailed proposal for whatever work is needed.
DuPage County sits in a storm corridor that sees regular severe weather — hail events, derecho-force wind events, and winter ice storms that test every component of a roofing system. Wheaton's position in the county's interior, away from the moderating influence of Lake Michigan, means it absorbs the full force of systems tracking across the Illinois plains.
After a significant storm event in Wheaton, out-of-state contractors arrive quickly, and homeowners are often approached before they've had time to assess what actually happened to their roof. The pressure to sign quickly and "get on the list" is a sales tactic, not a service. Here's a more useful sequence:
We document every storm inspection with photos and measurements. If you decide to pursue a claim, we'll work directly with your adjuster. If the damage doesn't justify a claim, we'll tell you that too.
Wheaton's commercial inventory runs along Roosevelt Road, the Naperville/Wheaton Road corridor, and the various retail and office developments throughout the city. The commercial base is substantial for a community of Wheaton's size, and property managers and building owners here have the same needs as anywhere in DuPage County — reliable flat-roof maintenance, prompt response to developing problems, and a contractor with the licensing and insurance to handle commercial scale work.
Leaders holds an Illinois Roofing Unlimited License, covering commercial work of any size and type without restriction. We install and maintain TPO, EPDM, modified bitumen, and built-up roofing systems for Wheaton commercial properties. We also handle commercial maintenance programs — scheduled inspections, seam and flashing re-sealing, drain clearing, and written condition reports that property managers need for capital planning and budgeting.
For property managers with portfolios that include multiple Wheaton commercial buildings, a systematic maintenance program extends flat-roof life significantly and reduces the frequency and severity of emergency repairs. A maintained commercial flat roof can serve 20–25 years; an unmaintained one often fails at 12–15, and the failure is rarely gradual.
Targeted repair is often the right answer for Wheaton homes that aren't yet at the end of their roofing system's life. Common repair situations we handle in Wheaton:
Wheaton's older homes — particularly those near downtown — have masonry chimneys that develop flashing failures as the original roofing cement dries and separates. Proper chimney flashing is a two-component system: step flashing integrated into the shingle courses and counter flashing embedded in the masonry joints. Caulk alone is a temporary patch. We reinstall chimney flashing correctly, addressing the masonry condition as needed.
Many Wheaton homes — particularly mid-century ranches and colonial-style homes built before modern ventilation standards — have insufficient ridge or soffit ventilation. The result is premature shingle aging from heat buildup in summer and ice dam formation in winter. We assess existing ventilation and recommend corrections as part of any inspection, whether or not a full replacement is the outcome.
Water stains on ceilings can originate from multiple sources — roof penetrations, valley failures, flashing separation, or even plumbing condensation. We trace leaks methodically before recommending any repair, identifying the actual source rather than assuming the most obvious culprit. Accurate diagnosis prevents expensive repairs in the wrong place.
Storm damage, tree impact, or sudden active leaks during the season — we respond to emergency situations in Wheaton. Temporary tarping or protective measures to stop water intrusion, followed by documented assessment and permanent repair.
Most Wheaton homeowners pay between $15,000 and $45,000 for a full roof replacement. The range reflects Wheaton's housing diversity — a straightforward ranch from the 1960s in the Arrowhead area will land on the lower end, while a larger colonial near downtown Wheaton with a steeper pitch, multiple dormers, and a masonry chimney requiring flashing work will be considerably higher. Homes in Danada and the newer subdivisions in the northwest part of the city typically fall in the $18,000–$32,000 range. We provide free estimates so you see every cost component before making any commitment.
Yes. Wheaton has an unusually high concentration of churches and religious organizations, and we have experience with steep-slope institutional structures — large-span gable roofs, complex hip and valley configurations, and the coordination challenges that come with working on occupied religious facilities. Institutional roofing on a church or school building is different from residential work in several ways: the roof spans are larger, the ridge heights are greater, access logistics are more complex, and scheduling around programming and services requires coordination. We've handled institutional projects in the Chicago suburbs and understand those requirements.
Wheaton requires a building permit for full tear-off roof replacements. We handle the permit application with the City of Wheaton Building Division on every project that requires one — you don't need to navigate that process yourself. Permit timelines in Wheaton typically run a few business days for standard residential projects, and we factor that into the project schedule. Working without a permit creates problems at resale and voids manufacturer warranties on some material systems — we don't skip that step.
Homes from that era require a more thorough evaluation before you get a final number. The deck condition is the critical variable — 1950s construction often used board sheathing rather than plywood, and its condition after 70 years of thermal cycling and moisture exposure varies considerably. A pre-project inspection will identify how much decking needs replacement, which affects both cost and timeline. Ventilation is also a common issue on older Wheaton homes — ridge and soffit ventilation was poorly understood in mid-century construction, and improving it as part of a replacement extends the new roof's life significantly. We'll walk you through what we find before you make any decisions.
Yes. We hold an Illinois Roofing Unlimited License covering commercial work without restriction. In Wheaton, that includes commercial properties along Roosevelt Road, the Naperville/Wheaton Road corridors, and the various office and retail developments throughout the city. We install and maintain flat and low-slope commercial systems — TPO, EPDM, modified bitumen, and built-up roofing — and offer commercial maintenance programs for property managers overseeing multiple Wheaton properties.
