Our Roof Repair Services in Mount Greenwood
Shingle Replacement
Mount Greenwood’s bungalows and ranch homes wear shingles hard. Summer attic heat cooks them from below; winter ice dams pry them from above. We replace damaged shingles with matching CertainTeed, Owens Corning, or IKO products - never a close-enough substitution. For homes with multiple layers, we perform full tear-offs to meet Chicago DOB requirements, then install proper underlayment and ventilation to prevent the same failure twice.

Leak Repair
Leaks in Mount Greenwood almost always trace to specific, diagnosable sources: failed vent boots on postwar ranches, separated valley flashing on bungalows, or ice-dam back-ups at the eaves. We don’t guess. Our crew traces the water path, documents it with photos, and fixes the actual breach - not just the symptom. We responded to a leak at a 1940s Chicago bungalow on Washtenaw Avenue where the original 3-tab shingles had been layered twice. Our crew performed a full tear-off, installed CertainTeed Landmark shingles, and fixed the chronic ice dam issue by adding ridge vents and insulation baffles to the under-ventilated attic - all with the required Chicago permit. The homeowner appreciated our one-trip heavy-duty approach.

Flashing Repair
Brick two-flats along Mount Greenwood’s side streets often have step flashing that has separated from mortar joints after ninety years of freeze-thaw. We remove, re-bed, and counter-flash these intersections with copper or coated aluminum that matches Chicago’s wind-driven rain exposure. No caulk-and-pray fixes. Proper flashing lasts the life of the roof.

Flat Roof Patch
The low-slope sections common on Mount Greenwood bungalow additions and rear porches demand different materials than pitched roofs. We patch with modified bitumen or TPO depending on the substrate, always extending patches well beyond the visible damage to account for water migration beneath the membrane. Chicago’s ponding-water ordinances apply here too - we slope and drain as we repair.

Valley Repair
Open valleys on Mount Greenwood’s hip-roof bungalows collect debris and corrode at the centerline, especially where oak overhang from the neighborhood’s mature canopy drops leaves that hold moisture. We rebuild valleys with proper woven or closed-cut methods, installing ice-and-water shield to the code-required depth before laying new shingles. This is where most Mount Greenwood leaks start; it’s where we pay closest attention.

Vent Boot Repair
Cracked rubber vent boots are a ten-minute fix that too many crews overlook. We carry standard and oversized boots for the cast-iron and PVC stacks common in Mount Greenwood’s housing stock, and we replace the surrounding shingles if they’ve been disturbed by prior leaks.

Common Roof Repair Problems We See in Mount Greenwood Homes
- Three-layer shingle stacks triggering DOB failures. Many Mount Greenwood bungalows still carry original shingles beneath two overlays. Chicago code now mandates full tear-off, and inspectors flag this specifically. Homeowners who hired cut-rate crews for overlay jobs have received stop-work orders mid-project, forcing a costly restart.
- Ice dams from under-ventilated attics. Those shallow-pitched bungalow roofs with minimal overhangs trap heat. Thirty-plus freeze-thaw cycles each winter melt snow from below; water runs to the cold eave and refreezes, lifting shingles and backing into soffits. We fix the roof damage and address the ventilation cause.
- Failed valley flashing on hip roofs. The intersection planes on Mount Greenwood’s Chicago bungalows create long valley runs that shed slowly. When flashing corrodes or shingles crack at the centerline, water enters in volumes that stain ceilings well downhill from the actual breach.
- Detached workshop and garage roof leaks. Mount Greenwood’s larger lots and acreage properties often have outbuildings with low-slope or shed roofs that were DIY-installed or repaired by owners unfamiliar with proper membrane or roll roofing. These leak at seams and penetrations that standard crews miss.

FAQs - Roof Repair in Mount Greenwood
Yes. Although Mount Greenwood feels suburban, it’s inside Chicago city limits (60655), so every roofing project requires a Chicago Department of Buildings permit and must comply with the Chicago Building Code. This is not the simpler suburban process used in Oak Lawn or Evergreen Park. Unpermitted work risks failed inspection, stop-work orders, and potential lien exposure. We pull permits as part of our standard workflow - no extra charge, no paperwork for you to chase. Call (855) 641-3418 and we’ll confirm permit requirements for your specific repair.
No, and any contractor who says otherwise is setting you up for a DOB failure. Chicago code mandates full tear-off when multiple layers exist, and Mount Greenwood inspectors specifically flag this condition. We’ve seen homeowners mid-project with stop-work orders after a cut-rate crew promised a quick overlay. We tear off properly, inspect decking, and install to code - one time, no revisits. For a free inspection of your layer count, call (855) 641-3418.
Yes. Mount Greenwood’s larger lots and acreage properties often have outbuildings with low-slope or shed roofs that need different materials and techniques than the main house. We repair these with proper membrane or roll roofing, extended at seams to prevent the leaks that DIY patches miss. Our crew carries the materials to fix workshop roofs in the same visit. Call (855) 641-3418 to schedule.
We install CertainTeed, Owens Corning, IKO, Atlas, and four additional manufacturer lines, matched to your existing roof and local wind rating. For Mount Greenwood’s typical bungalow and ranch architecture, CertainTeed Landmark and Owens Corning Duration are the most common selections. We stock regional supply so we’re not waiting on delivery. Call (855) 641-3418 to discuss color and grade options for your repair.
Ice dams form when heat escapes through an under-ventilated attic, melting snow from below; water runs to the cold eave and refreezes. Mount Greenwood’s 1925-1955 bungalows are especially prone - shallow pitches, minimal overhangs, and original insulation that barely meets modern standards. Thirty-plus annual freeze-thaw cycles make it worse. We fix the immediate roof damage and can address ventilation and insulation improvements that reduce recurrence. For an inspection that includes attic airflow assessment, call (855) 641-3418 - estimates are free.
