Chicago’s roofs are not like other cities’ roofs. The two-flat and three-flat buildings that define our neighborhoods carry flat membranes, not shingles. The Chicago bungalow on the southwest side wears a low-pitched hip roof found almost nowhere else in America. And our 100-plus annual freeze-thaw cycles punish every flashing, every seam, every layer of built-up roofing that previous contractors left behind. We’ve been climbing these roofs since 1984. We know what fails here, and we know how to fix it so it stays fixed.

Our Roof Repair Services in Chicago
Flashing Repair
On Chicago’s brick two-flats, the counterflashing where the flat roof meets the parapet wall is the single highest-failure detail in our market. Freeze-thaw cycles steadily pull the flashing out of aging mortar joints, and because most owners don’t access their roofs, a $400 reflashing repair quietly becomes a $15,000 interior plaster and structural repair before anyone notices. We responded to a leak at a three-flat in Logan Square where the tenant noticed water stains on the third-floor ceiling. On the flat roof, we found the counterflashing had pulled loose from the parapet wall - a classic Chicago failure from 100-plus freeze-thaw cycles. We reflashed with a new GAF membrane and counterflashing system, stopping further water intrusion before it damaged the plaster.
Flat Roof Patch
Chicago’s flat-roofed buildings frequently carry three or four accumulated layers of old built-up roofing beneath the current surface. That makes tear-offs significantly heavier and more labor-intensive than a typical suburban re-roof job. But it also means leaks can travel laterally between layers, making the source hard to find. We cut through the strata methodically, locate the true breach, and patch with modified bitumen or TPO membrane matched to your existing system. For ponding water from improper slope - common on older two-flats in Pilsen and Bridgeport - we install tapered insulation crickets to move water toward drains.
Leak Repair
Ice damming on Chicago’s flat-roofed buildings accumulates at parapet walls rather than eaves, a failure mode specific to our building typology that many out-of-town roofers misdiagnose. They look for gutter problems that don’t exist while water backs up behind the parapet and seeps through masonry. We know the difference. Our leak repairs on Chicago homes address the actual source: failed membrane at the parapet base, cracked vent boots from thermal cycling, or separations in valley metal on Chicago bungalows in neighborhoods like Portage Park.
Shingle Replacement
Chicago’s 80,000 bungalows - that distinct low-pitched hip-roof form concentrated on the southwest and northwest sides - wear asphalt shingles in a configuration you won’t see in suburban markets. The shallow pitch demands precise underlayment and ice-barrier placement. We replace wind-damaged or curled shingles with Atlas or Tamko products rated for our temperature swings, and we always inspect the decking beneath because Chicago’s humidity and attic ventilation issues cause hidden rot.

Common Roof Repair Problems We See in Chicago Homes
- Counterflashing detachment at parapet walls. Chicago’s 100-plus freeze-thaw cycles pull counterflashing from aging mortar joints on two-flats and three-flats. The gap is often invisible from the street but channels water directly into the wall cavity. By the time interior stains appear, structural members may be compromised.
- Ponding water on improperly sloped flat roofs. Heavy snow loads and ice accumulation at parapets - not eaves - create chronic standing water that degrades modified bitumen and TPO membranes. This is especially common on 1920s-era buildings in Douglas and the Near South Side where original drains were undersized.
- Hidden leaks beneath multiple built-up roofing layers. Three or four accumulated roofing systems are standard on Chicago flat roofs. Water travels laterally between layers, masking the true source until plaster ceilings collapse or roof decking rots through.
- Thermal splitting in Chicago bungalow shingles. The city’s temperature swings from below-zero January nights to 95-degree July days cause asphalt shingles to expand and contract beyond their design tolerance. We see thermal cracking concentrated on south- and west-facing bungalow hips in neighborhoods like Archer Heights and Belmont Cragin.

FAQs - Roof Repair in Chicago
Because the counterflashing where the flat roof membrane meets the parapet wall is the single highest-failure detail in Chicago roofing. Our 100-plus annual freeze-thaw cycles expand and contract the metal until it pulls loose from aging mortar joints, creating a gap that channels water directly into the wall cavity. This failure mode is so common here that out-of-town roofers often misdiagnose it as a gutter or drain problem. We inspect the parapet-to-wall interface on every flat roof call, and we reflashed with proper membrane integration to stop the cycle. Call (855) 641-3418 - estimates are free.
Three or four accumulated layers of built-up roofing are standard on Chicago’s older two-flats and three-flats, with some buildings carrying even more. Each layer adds weight, complicates leak detection, and increases tear-off labor. We cut test cores to count layers before quoting, so you know exactly what the job involves. Call (855) 641-3418 and we’ll inspect your roof’s layer history - estimates are free.
Most localized flat roof damage on Chicago buildings can be patched if the underlying structure is sound and the membrane failure is limited to a defined area. We replace when the roof has widespread alligatoring, saturated insulation, or multiple chronic leak points that patching would only chase around. Our inspection includes moisture probing and core samples to give you an honest repair-versus-replace recommendation. Call (855) 641-3418 for a free assessment.
Yes, the City of Chicago requires a permit for most roof repair work beyond minor shingle replacement, and flat roof work almost always requires permitting through the Department of Buildings. We handle permit application and inspection scheduling as part of our standard process - you don’t need to navigate City Hall yourself. Our 42 years of Chicago work means we know the inspectors, the paperwork, and the common hold-ups. Call (855) 641-3418 and we’ll walk you through what’s needed for your specific job.
Fall - September through early November - offers the most reliable conditions for flat roof work in Chicago, with moderate temperatures that allow proper membrane adhesion and sealant curing. But we repair roofs year-round, including winter emergency calls. Cold-weather work requires modified installation techniques and cold-weather adhesives that we stock specifically for Chicago’s conditions. Waiting until spring with an active leak risks the $400 reflashing becoming that $15,000 interior repair. If you see water, call (855) 641-3418 - we’ll fix it when it needs fixing.
