Our Roof Repair Services in Highland Park
Leak Repair
Leaks in Highland Park homes rarely come from obvious places. Lake-driven moisture finds its way through degraded valley flashings, corroded vent boots, and the freeze-thaw gaps that open at dormer cheeks on 1920s Tudors. We trace the water path methodically - photo-documenting every step - then repair the source, not just the symptom. Most leak repairs in Highland Park run $450-$950 and are completed in one visit.
Flashing Repair
The deep eave overhangs on Highland Park’s historic Colonials and Prairie-influenced homes require specialized flashing details that standard contractors often miss. We fabricate and install custom step flashing, counter-flashing, and apron flashing using matching metals - copper on period homes where appropriate, painted steel where specified. Proper flashing repair on these older homes typically costs $400-$1,200 depending on linear footage and access difficulty.
Valley Repair
Roof valleys take the hardest beating in Highland Park’s climate. Concentrated runoff, ice-dam pressure, and the architectural complexity of multi-plane roofs common in the Eastwood and Braeside neighborhoods mean valley failures are frequent here. We strip to solid decking, install ice-and-water shield appropriate to the slope, and re-shingle with matching materials - GAF WeatherWatch or CertainTeed WinterGuard depending on the application. Valley repairs in Highland Park generally run $800-$1,800.
Shingle Replacement
When wind or age damages sections of an otherwise sound roof, we match existing shingles from our authorized lines - Atlas, GAF, and CertainTeed are our most common in this market. For Highland Park’s high-end homes, we stock architectural and designer-grade options, never substituting without explicit approval. Spot shingle replacement typically runs $350-$750.
Flat Roof Patch
Carriage houses, additions, and mid-century modern homes in Highland Park’s Ravinia and Sherwood Forest areas often have low-slope sections that demand Specialty Roofing in Highland Park - membrane-specific repair with TPO, EPDM, or modified bitumen. We identify the existing system, clean and prime properly, and weld or adhere patches that outlast the surrounding field. Flat patches here run $500-$1,400.
Vent Boot Repair
Cracked or improperly sealed vent boots are a common entry point for the persistent northeast-driven rain that hits Highland Park’s lake-facing slopes - one reason Gutters & Accessories in Highland Park homes need proper drainage systems working in tandem with roof repairs. We replace with properly sized, color-matched boots and seal with manufacturer-approved methods. Most vent boot repairs are $250-$450.

Common Roof Repair Problems We See in Highland Park Homes
- Ice dams at broad eave overhangs. The classic older North Shore home design - generous overhangs for aesthetics and shade - becomes a liability when lake-effect snow meets northeast winds. Meltwater refreezes at the cold edge, backs up under shingles, and enters through soffits and exterior walls. We see this repeatedly on homes near the lakefront and in the Braeside area.
- Moss and lichen degradation of wood shakes. Persistent lake-generated moisture keeps north- and east-facing slopes damp year-round. On Highland Park’s original cedar-shake roofs, this shortens lifespan dramatically and lifts shakes, creating wind-driven leak paths. The moss itself isn’t just cosmetic - it holds moisture against the wood and accelerates rot.
- Freeze-thaw damage at valleys, dormers, and chimney flashings. Highland Park’s temperature swings are particularly severe within a mile of the lake. Water enters microscopic gaps in flashing cement or mortar, expands when frozen, and widens the breach. By spring, what was a hairline opening is a steady leak - most common on the 1910s-1930s housing stock that defines the city.
- Ravine-lot access complications. Highland Park’s deep-ravine topography means many homes have roof faces that drop sharply away from the street, forcing crews to hand-carry materials through the house or rig from above - a logistical premium that every ravine-lot repair estimate must include upfront. Standard lift equipment simply cannot reach these slopes, and contractors who don’t plan for this mid-job create damage, delays, and cost overruns.

FAQs - Roof Repair in Highland Park
Yes. Ravine-lot homes throughout Highland Park - particularly in the Eastwood, Braeside, and Sherwood Forest areas - often have slopes that drop too steeply for ladders or lift equipment. We recently repaired a leak at the valley flashing on a 1920s Tudor Revival in the Eastwood neighborhood near Sheridan Road. The ravine-facing slope was inaccessible to ladders and lifts, so our crew hand-carried new GAF WeatherWatch ice-and-water shield and CertainTeed XT-25 shingles through the owner’s kitchen and out a second-story dormer window to complete the work. We build this access planning into every ravine-lot estimate upfront - no mid-job surprises. Call (855) 641-3418 and we’ll walk through your specific situation.
Persistent lake-generated moisture from Lake Michigan keeps north- and east-facing slopes damp for months at a time, creating ideal conditions for moss and lichen colonization. On wood shakes - common on Highland Park’s 1910s-1940s homes - this moisture penetration lifts grain, promotes rot, and shortens lifespan by 30-50% compared to inland exposures. The moss isn’t just cosmetic; it holds water against the wood like a sponge. We can treat active growth, replace degraded shakes with matching cedar, and recommend ventilation improvements that reduce future moisture retention. For a specific assessment of your north slope, call (855) 641-3418 - estimates are free.
Yes, and in most cases that’s the right approach for a sound slate roof. We source matching slate by color, thickness, and exposure length - critical on Highland Park’s historic homes where inconsistent repairs are visually jarring. Individual slate replacement typically runs $75-$150 per slate plus access setup, with most localized repairs totaling $500-$1,200. We also inspect the underlying flashings and fasteners while we’re there, since the same age that cracks slate often corrodes copper nails. Pete Callahan has overseen slate repair on North Shore homes since 1984; we’ll tell you honestly whether spot repair or larger section replacement makes sense. Call (855) 641-3418 to schedule.
We match the flashing to the period and the problem. For deep eave overhangs on Highland Park’s Tudors and Colonials, we typically install custom-fabricated copper or pre-finished steel step flashing with a minimum 4-inch vertical leg, paired with ice-and-water shield extending 24 inches inside the wall line. At chimney and dormer intersections, we use counter-flashing reglets cut into mortar joints - not surface-sealed strips that fail within five years. The exact profile varies by roof pitch and eave depth; we measure and fabricate on-site rather than using pre-made pieces that don’t fit. Most flashing repairs on these older homes run $400-$1,200. For a specific quote on your eave details, call (855) 641-3418.
Prevention requires addressing heat loss, ventilation, and mechanical protection together. We install ice-and-water shield extending 24 inches past the interior wall line at eaves and valleys - code minimum, but often insufficient for Highland Park’s lake-effect loads, so we frequently extend to 36 inches. We also inspect attic insulation and ventilation, since heat escaping through the roof deck is what creates the melt-refreeze cycle in the first place. For homes with chronic ice dam history, we may recommend ridge venting upgrades or targeted air sealing. Our $89 Seasonal Tune-Up includes a full eave and attic inspection with photo documentation. To schedule or discuss your specific eave configuration, call (855) 641-3418.
