Fast, Reliable Roof Replacement & Installation Across Markham
Roof replacement in Markham, Illinois typically runs $8,500-$18,000 for a standard asphalt shingle tear-off on a 1,200-2,000 square foot ranch, with most jobs completed in two to three days. If you’re calling from a post-war home near 159th Street or Pulaski Road, you’re probably looking at a roof that was last done in the 1980s or 1990s with basic 15-lb felt and no eave protection. That’s the reality of Markham’s housing stock, and it’s why we approach every job here differently than we would in a newer suburb.
We’ve been driving to Markham since 1984. Our crews know the difference between a 1955 ranch off Crawford Avenue and a 1972 split-level near Interstate 294. We answer the phone live at (855) 641-3418, day or night, and we can usually have a technician out for a photo-documented inspection within 24 hours. No voicemail trees. No callback windows.
Markham sits on the open Chicago Southland plain with no hills or tree lines to break the wind. That flat terrain drives rain hard against western and southern roof faces, and it means ice dams form with brutal reliability every winter. A roofer who doesn’t account for those conditions is guessing. We don’t guess.
Why Ridgeline Roofing Co. of Chicago Is Markham’s Preferred Roof Replacement & Installation Company
We’ve replaced roofs on Markham homes for over four decades. Pete Callahan, who leads our company, started this work in the early 1980s when much of Markham was still under its original roofing. That continuity matters. A homeowner in the 60428 ZIP code knows that the same company who roofed their neighbor’s house in 1998 is still here, still answering the phone, still honoring its word.
Our reputation in Markham is built on one thing: we come back if something isn’t right. The 90-Day Done Right Promise is written, not spoken. No paperwork to file. No arguments. If it’s not right, we make it right. That’s held for 42 years.
When you call (855) 641-3418, a live person answers. At 2 AM during a February ice storm, at noon on a Sunday, at 7 PM on a weeknight. We’ve taken calls from Markham homeowners standing in their living rooms with buckets catching drips, and we’ve had crews on-site within hours. Not because we’re heroes. Because that’s the job.
Our technicians are background-checked and uniformed. They photograph every roof from the deck up, not from the driveway with a zoom lens. You’ll see what we see: the delaminated plywood, the degraded felt, the granule loss patterns that tell the story of which way Markham’s prevailing winds blow.
Our Roof Replacement & Installation Services in Markham
Full Roof Replacement
Most Markham full replacements we do are on 1950s-1970s ranches that have never had a proper tear-off. The original 3:12-pitch roofs were built with 15-lb felt, no drip edge, and no ice-and-water shield. That was standard for the era, but it doesn’t meet code today and it doesn’t survive Cook County’s freeze-thaw cycles. Our Roof Replacement & Installation team strips to the deck, replaces any compromised plywood or board decking, and installs full underlayment with self-adhering shield across the lower third of the roof. On a 1963 ranch home on 166th Street, we found the original 15-lb felt completely degraded and the CDX plywood delaminated from decades of trapped moisture. After replacing half the decking, we installed full underlayment with GAF ice-and-water shield at the eaves and CertainTeed Landmark shingles, ensuring the low-slope roof would withstand the next freeze-thaw cycle.
New Construction Roofing
New builds in Markham are rare compared to re-roofs, but when they happen, we spec them correctly from day one. That means proper attic ventilation for the flat Southland terrain, ice-and-water shield at all valleys and eaves, and shingles rated for the wind exposure that open prairie land creates. We don’t install the same roof we’d put on a sheltered lot in a wooded suburb.
Asphalt Shingle Installation
Asphalt shingles remain the practical choice for Markham’s modest ranch homes. We install IKO and Atlas lines with full manufacturer warranties, and we match the shingle profile to the roof pitch. On a 3:12 slope, standard three-tab shingles aren’t appropriate; architectural shingles with proper sealant strips perform better against wind uplift. We stock common colors locally so Markham homeowners aren’t waiting six weeks for special orders.
Flat Roofing
Markham’s low-pitch ranches blur the line between sloped and flat roofing. Any pitch below 4:12 requires modified bitumen or TPO membrane in valleys and at transitions, not just shingles. We’ve seen too many “shingle-only” jobs on 3:12 Markham roofs that failed within five years because the installer treated a low slope like a standard pitch. We don’t make that mistake.
Metal Roofing
Metal makes sense for some Markham homeowners who want a 50-year solution and don’t mind the higher upfront cost. Standing seam metal performs exceptionally well on low pitches and sheds ice more effectively than asphalt. We install Tamko metal profiles where the home’s structure and the homeowner’s budget align with the investment.

Trusted Brands We Service in Markham
We are authorized installers for seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Markham’s typical re-roof, we most often specify IKO Cambridge architectural shingles or Atlas StormMaster Slate for their wind resistance and color stability. We maintain relationships with regional distributors, so replacement materials for warranty claims or repairs arrive quickly. No homeowner in the 60428 ZIP code should wait three weeks for matching shingles because a contractor cut corners on supplier relationships. We don’t.
Common Roof Replacement & Installation Problems We See in Markham Homes
- Delaminated board decking under original 15-lb felt. On Markham ranches built before 1975, we regularly pull up shingles to find solid board or early CDX plywood that has gapped, warped, or turned to mush from trapped condensation. A shingle-over job hides this. A proper tear-off exposes it, and we replace every compromised sheet before the new roof goes down.
- Ice dams at unshielded eaves on 3:12 pitches. Markham’s low-slope ranch roofs are chronic ice-dam factories. Without self-adhering underlayment across the lower third of the deck, meltwater backs up under shingles and rots soffits from the inside out. We’ve replaced fascia boards that looked fine from the ground but were hollow behind the gutter.
- Accelerated granule loss on western and southern exposures. Markham’s flat terrain offers no windbreaks. Prevailing westerlies and southerly storm fronts drive rain at roof faces with sustained force. We see 15-year shingles bald on one slope and intact on the other. We account for this in our material specs and our ventilation recommendations.
- Improper prior repairs that trapped moisture. Caulk patches, mismatched shingles, and vent boots sealed with roofing cement instead of replaced. Markham’s older homes have decades of this kind of “maintenance.” We document it all in our inspection photos so homeowners understand why a full replacement is sometimes the only honest recommendation.

FAQs - Roof Replacement & Installation in Markham
Because your 1960s ranch was built with 15-lb felt and no eave protection, and Cook County’s 30-40 annual freeze-thaw cycles will eventually force water through any low-slope roof without self-adhering underlayment. The absence of past leaks doesn’t predict future performance; it only means you’ve been lucky or the damage is still hidden in your soffits. We install ice-and-water shield across the lower third of every Markham re-roof. It’s not optional, and it’s not upsell. Call (855) 641-3418 if you want us to show you what we’re finding on roofs just like yours.
Partial deck replacement is needed on roughly 60% of Markham re-roofs we do on pre-1975 homes, and full replacement on about 15%. The original solid board or early CDX plywood has often trapped moisture under degraded felt for decades. We can’t know until we strip the roof, but we build deck replacement into every estimate so you’re not surprised. Our photo inspection usually reveals telltale sponginess at the eaves and valleys. Call (855) 641-3418 and we’ll show you what to expect.
No. On Markham’s 3:12-pitch ranches, a shingle-over job traps existing moisture, hides deck damage, and adds weight to structure that wasn’t engineered for it. More critically, it prevents installation of the ice-and-water shield that these roofs require. We don’t offer shingle-over services on low-slope Markham homes. It’s a disservice. Call (855) 641-3418 for a tear-off quote that includes proper underlayment.
IKO Cambridge and Atlas StormMaster Slate perform well on Markham’s 3:12 to 4:12 pitches because their sealant strips and laminate construction resist wind uplift better than basic three-tab products. We also specify GAF Timberline HDZ where homeowners want the broadest color selection. The brand matters less than the installation detail: proper underlayment, correct nail placement, and adequate ventilation. Call (855) 641-3418 to discuss which line fits your home and budget.
Markham’s open, flat geography exposes roofs to unbroken wind and driving rain from the west and south, accelerating granule loss and sealant fatigue. Without topographic shelter, a 25-year shingle in Markham may show wear patterns in 18-20 years that a sheltered roof wouldn’t show until year 22-25. We account for this in our material recommendations and our ventilation designs. The right roof for Markham is not the same as the right roof for a wooded lot. Call (855) 641-3418 and we’ll explain what that means for your specific home.
