Leaders Roofing has been a family-owned Chicagoland roofing contractor since 1996, operating from the same Mount Prospect office under the same Illinois Roofing Unlimited License #104.010248. We work commercial property portfolios and estate-home residential — and we built the business one referral at a time.
The Mount Prospect / Elk Grove Village / Arlington Heights / Wheeling / Bensenville / Des Plaines industrial corridor is our home territory. We've worked it for 30 years. We carry maintenance contracts on multi-tenant warehouses, industrial parks, retail centers, and multi-family properties. Our crew is on a roof for assessment within a day or two of your call, and our commercial scope spans TPO, EPDM, modified bitumen, built-up, silicone coatings, and full tear-off replacement.
Why we're worth a 15-minute call: we know your buildings — even if we haven't worked on them yet. We've seen what the original specifications were across this corridor for 30 years. We give you a real capital-planning baseline, not a sales pitch.
Cedar shake, natural slate, synthetic slate, copper flashing, designer architectural shingle. We've worked Winnetka, Glencoe, Kenilworth, Highland Park, Lake Forest, Lake Bluff, Bannockburn — the architectural review jurisdictions, the HOA covenants, the historically-correct material specifications. When the architectural review board has to approve your roof material before tear-off, we've been through that submission process more times than we can count.
Why we're worth a 15-minute call: we'll tell you what the right specification is for your specific home — and we'll tell you when a less expensive material is the right call, too. That's not a sales tactic. That's how the business has lasted 30 years.
We're a mid-sized family-owned operation — large enough to handle complex multi-month estate projects or multi-property commercial portfolios, small enough that the owner is involved on every project. Capacity scales with crew availability; for new commercial portfolios we typically have a 2-4 week onboarding window before we're embedded in the maintenance schedule.
Residential replacement projects typically run $15,000–$60,000 for standard homes, $80,000–$300,000 on premium-materials estate properties (cedar shake, slate, designer architectural). Commercial flat-roof projects run $50,000–$500,000+ depending on building size and system. Targeted repairs run $1,500–$30,000. Capital planning and maintenance contracts on multi-property portfolios scale with property count.
No. We do storm-damage repair work for our existing customers when their roof takes a hit, and we document insurance scope properly for adjusters. But we don't chase storms, don't do door-to-door post-storm sales, don't pressure customers to file claims, and don't waive deductibles (which is illegal in Illinois). If you're looking for that contractor profile, we're not it. If you've had a bad experience with one and want a contractor who won't operate that way, we're worth a call.
We've worked through Lake Forest Historic Preservation Commission, Winnetka village review, Highland Park preservation overlays, Bannockburn private covenants, and most North Shore village permit processes. We submit material samples, scope documents, and color boards as required. Approval timelines run 4-8 weeks on designated properties. We've never had a project rejected at review when the material specification was historically appropriate.
Structured preventive maintenance contracts — quarterly visual inspections, post-storm assessments, repair-as-needed at contract pricing, 5-year capital plan documentation. We pair the maintenance contract with annual capital planning meetings so property managers have realistic budget forecasts for upcoming TPO, modified bitumen, or built-up replacements. The goal is no surprises in your operating budget.
Yes. We have references in the specific property type and geography you're working in. For commercial property managers we can typically share 3-5 references in your specific submarket. For estate-home owners we can share references on the specific material specification you're considering (cedar shake, slate, copper flashing, designer architectural). Available on request before any commitment.
Cheapest contractor at signing is almost never cheapest at year 10.
Aluminum flashing, basic underlayment, 25-year nominal warranty. Realistic lifespan in Chicagoland: 15-18 years. Failed flashing leads to interior water damage at year 12. Lifetime cost across 30 years: roughly $58K-$72K including ongoing repair and earlier replacement.
Soldered copper flashing at all leak-risk junctions, full ice-and-water shield, Class IV impact-resistant shingles, manufacturer-extended warranty. Realistic lifespan: 25-30 years. Insurance discount for Class IV. Lifetime cost across 30 years: roughly $42K-$48K including normal maintenance, no early replacement.
Premium material, soldered copper flashing throughout, architectural-review submission included. Realistic lifespan: 30 years (cedar) or 50+ years (synthetic slate). On a multi-generational hold, the math works out across one roof cycle. On an under-10-year ownership horizon, this is overspec — and we'll tell you that.
We'll run the math against your specific home, ownership horizon, and budget. There's no pitch — just the honest comparison so you can decide.
"I founded Leaders Roofing in 1996 because I believed there was room in this industry for a contractor who would treat customers the way I'd want my own family treated — honest estimates, real craftsmanship, and someone who answers the phone when something goes wrong five years later. Thirty years in, that's still the standard. If we reached out to you, it's because we believe there's a fit between what you need and how we work. I'd welcome the conversation."
