We’ve been climbing roofs in Forest Park since 1984, back when the village was still finding its footing after the Eisenhower Expressway carved through. Pete Callahan and our crews know the difference between a 1920s Chicago bungalow on Hannah Avenue and a 1950s two-flat near Roosevelt Road - not because we read about them, but because we’ve torn off their roofs, replaced their rotted sheathing, and stopped their leaks at the parapet lines. Forest Park’s housing stock is unlike anything west of Austin Boulevard: dense, old, and almost always hiding a dual-system roof that demands a contractor who understands both sloped asphalt work and flat membrane installation on the same structure.

Our response time to Forest Park averages under 24 hours for standard inspections and same-day for emergency leaks during active storms. We hire local crews who live in the western suburbs, not day-laborers pulled from a parking lot.

We’ve earned our reputation one square deal at a time. The price we quote is the price you pay. That matters in Forest Park, where a roof replacement is often the largest home repair a longtime homeowner will face, and where trust is built slowly and lost in an afternoon.
Our Roof Replacement & Installation Services in Forest Park
Full Roof Replacement
Most full replacements in Forest Park involve both a sloped system and a flat system on the same structure - a reality that defines our work here. On a brick two-flat on the 800 block of Marengo Avenue, we tore off five layers of asphalt shingles and old roll roofing to find the original 1×8 board sheathing rotted where a prior re-roof had lapped over a failed parapet step flashing. We replaced 120 square feet of decking, installed Owens Corning Duration shingles on the sloped front, and a fully adhered TPO system over the flat rear addition, tying both into a new integrated flashing system that eliminated the recurring leak at the roof transition. That’s the standard we hold for every job in Forest Park: done right, and if it’s not, we make it right.

New Construction Roofing
New builds are rare in Forest Park’s built-up 1.5 square miles, but when they happen - additions, coach house conversions, or infill on Madison Street - we install complete systems from day one. We spec proper ventilation, ice-and-water shield at all eaves and valleys, and manufacturer-warranted systems that match the village’s architectural review requirements. Getting it right the first time on new construction means never having to revisit it.

Asphalt Shingle Installation
The pitched portions of Forest Park bungalows and two-flats demand asphalt shingles that can handle Chicago’s temperature swings and the weight of winter snowpack. We install GAF Timberline HDZ and CertainTeed Landmark lines with proper synthetic underlayment and drip edge at all rakes and eaves. On older homes with 1×6 or 1×8 board sheathing, we always inspect for spacing, rot, and nail-holding capacity before fastening - a step that less careful crews skip, and that homeowners pay for later when shingles blow off in a March windstorm.

Metal Roofing
Standing-seam metal makes sense for select Forest Park properties, particularly where homeowners want 50-year durability on a steep-slope section or where historical guidelines favor the material. We install concealed-fastener systems in aluminum and steel, properly flashed at all penetrations and transitions. Metal isn’t right for every Forest Park roof - the flat rear additions still need membrane - but where it fits, it performs.

Flat Roofing
The rear additions on Forest Park bungalows and two-flats are where roofs live or die. We install modified bitumen and fully adhered TPO systems, always addressing the critical transition where the sloped front meets the flat rear. That junction is the leak point we’ve seen more times than we can count. Ponding water, ice damming, and membrane cracking from 20-plus annual freeze-thaw events make Forest Park’s flat roofs a specialty, not an afterthought.

Tile Roofing
Clay and concrete tile appear on select Forest Park properties, often on Spanish Revival or Mediterranean-influenced designs near the Des Plaines River corridor. We handle tile replacement, underlayment renewal, and structural verification for the added weight. Tile systems demand proper battens, flashings, and valley treatments - we don’t cut corners on installation because tile doesn’t forgive shortcuts.

Trusted Brands We Service in Forest Park
We install GAF, CertainTeed, Owens Corning, Atlas, Tamko, and Boral products - seven manufacturer lines, properly specified for Forest Park’s climate and building stock. We don’t substitute materials without your knowledge. What we specify is what arrives on your roof. Our relationships with regional distributors mean most shingle colors and flat membrane rolls are available within a few days, not weeks. For Forest Park homeowners facing an active leak, that turnaround matters. We keep common GAF and CertainTeed profiles in rotation for faster deployment, and our Tamko Heritage lines offer solid value for budget-conscious replacements on rental two-flats where the owner still wants a 30-year shingle.
Common Roof Replacement & Installation Problems We See in Forest Park Homes
- Layered roofs hiding rotted sheathing. Many Forest Park homes carry three, four, even five layers of old roofing over original 1×6 or 1×8 board decking. Tear-offs routinely uncover rot at eaves, around chimneys, and beneath failed flashings. We replace all compromised decking before installing new systems - no exceptions.
- Freeze-thaw destruction of flat rear membranes. Forest Park endures 20 or more freeze-thaw cycles each winter. Water that seeps into cracks expands, contracts, and expands again. By March, a membrane that looked sound in October has developed splits at seams and perimeter flashings.
- Parapet flashing failures on two-flats. Original or 1970s-era coping and step flashing was never properly integrated with subsequent re-roofing work. Experienced local roofers know to probe parapet tops and interior corners first, because that hidden flashing failure - not the field membrane - is almost always where the leak originates.
- Ice damming at sloped-to-flat transitions. The junction where a bungalow’s pitched roof meets its flat rear addition creates a natural collection point for snowmelt and refreeze. Without proper ice-and-water shield and adequate insulation, water backs up under shingles and into wall cavities.

FAQs - Roof Replacement & Installation in Forest Park
The typical Forest Park bungalow or two-flat was built with a low-slope hip roof over the main structure and a flat or near-flat rear addition - two different systems sharing one building. Replacing only the sloped shingles while leaving a failing flat membrane means water still enters at the rear, undermining your new work. We almost always recommend addressing both systems together for a watertight, integrated result. Call (855) 641-3418 for a free inspection and honest assessment of whether both need attention now.
Look for water stains on interior walls near the building’s perimeter, especially at upper-floor corners and ceiling lines adjacent to parapet walls. Exterior clues include deteriorated coping stones, rusted or missing metal caps, and cracked mortar at parapet tops. On a recent job near Roosevelt Road, the homeowner had chased “roof leaks” for three years before we found the actual source: original 1920s step flashing behind the parapet that had separated from the wall. We probe these areas first on every Forest Park two-flat inspection. Call (855) 641-3418 and we’ll show you exactly what we find.
Yes. The village’s 80-to-110-year-old housing stock was originally roofed over 1×6 or 1×8 board sheathing, not modern plywood. Decades of layered re-roofs trap moisture against that wood. When we tear off, we routinely find rot at eaves, around chimneys, and beneath failed flashings - sometimes 20% or more of the deck needs replacement before new roofing can be installed. We build this possibility into every estimate so you’re not surprised mid-job. Call (855) 641-3418 for an inspection that includes sheathing assessment.
For most Forest Park flat roofs, we recommend either a multi-ply modified bitumen system or a fully adhered TPO membrane, depending on the substrate condition and your budget. TPO offers excellent reflective properties and strong seam welding, which performs well against our 20-plus annual freeze-thaw cycles. Modified bitumen handles foot traffic and mechanical stress better, a consideration if your rear roof serves as a utility or deck space. We’ll recommend the right system after inspecting your specific structure. Call (855) 641-3418 for a free evaluation.
Forest Park typically experiences 20 or more freeze-thaw cycles between November and March, as Chicago’s continental climate pushes temperatures above and below 32°F repeatedly. Each cycle forces water into microscopic cracks, where it expands when frozen and contracts when thawed. By spring, those cracks have propagated through shingles, membrane seams, and flashings. This is why Forest Park’s flat rear additions fail faster than steep-slope sections - water lingers longer on low-slope surfaces, giving freeze-thaw more opportunities to work. Proper drainage, adequate slope, and quality membrane installation are your defenses. Call (855) 641-3418 to schedule pre-winter inspection or replacement.
