Why Ridgeline Roofing Co. of Chicago Is Forest Park’s Preferred Specialty Roofing Company
We’ve served Forest Park homeowners for over 42 years, long enough to have re-roofed the same Circle Avenue two-flat twice as ownership changed hands. Our Specialty Roofing team knows the village’s 60130 ZIP by heart: the low-slope hips meeting flat rear additions, the parapets with original coping that outlasted three membrane layers, the freeze-thaw cycles that crack modified bitumen by February.
Our technicians are background-checked and uniformed - the same standard we’d hold for work on our own mother’s home. Every inspection is photo-documented from the roof itself, not the driveway. Most Forest Park jobs are completed in a single visit, with upfront pricing that means the number on the estimate matches the number on the invoice.
A live person answers our phones 24 hours a day, seven days a week, including the middle of a storm. When water’s coming through your plaster ceiling at 2 a.m., you won’t reach a voicemail tree.
Our Specialty Roofing Services in Forest Park
TPO Roofing
TPO is our most common recommendation for Forest Park flat rear additions - the white reflective membrane handles the village’s heavy summer sun and shrugs off the 20-plus annual freeze-thaw events that destroy darker systems. A typical TPO installation on a bungalow’s rear addition runs $4,200-$7,800 in Forest Park, including tear-off of old modified bitumen and replacement of any rotted decking at the transition. We install TPO from authorized lines including Carlisle and GAF, with seams hot-air welded on site, not taped.

Modified Bitumen
Modified bitumen still has its place on Forest Park’s smaller roofs and parapet walls, particularly where budget constraints matter or where the existing slope drains adequately. We recently serviced a 1920s brick two-flat on Circle Avenue where the rear flat section had ponding water from aged modified bitumen that was original to the 1980s re-roof. The leak traced back to a parapet coping that had never been properly integrated with the field membrane - a hidden failure we routinely probe first. We tore off the old layers, replaced rotted decking at the transition, and installed a new TPO system with fully integrated step flashing at the parapet. Modified bitumen replacement on similar Forest Park structures typically runs $3,800-$6,500.

Built-Up Roofing
Built-up roofing, the old gravel-and-tar system, still protects some of Forest Park’s commercial strips and courtyard apartment buildings along Roosevelt Road. When it’s time to replace, we evaluate whether to stay with BUR or transition to a modern membrane. Full BUR replacement in Forest Park runs $5,500-$9,200 depending on gravel removal, deck condition, and access constraints common to the village’s narrow lots and alley-facing rear additions.

Solar Ready Roofing
Forest Park homeowners adding solar to their bungalow’s south-facing hip need a roof that will outlast the panels. Our solar-ready installations use elevated attachment points and reinforced membrane at penetrations, installed with Owens Corning and CertainTeed components sized for the panel load. A solar-ready TPO base system in Forest Park runs $6,800-$11,500 before panel installation.

Trusted Brands We Service in Forest Park
We stock Forest Park’s most common membrane and flashing components locally, which means faster turnaround when your two-flat’s rear addition starts leaking into the kitchen. As an authorized installer, we source directly from CertainTeed, Owens Corning, IKO, and Atlas - no substitutions, no “equivalent” products that don’t match the specification. For flat systems, we carry TPO and modified bitumen from GAF and Carlisle with same-week availability for most Forest Park jobs. The materials matter, but so does the hand that installs them. We’ve trained apprentices into journeymen on Forest Park roofs for four decades.
Common Specialty Roofing Problems We See in Forest Park Homes
- Ponding water and freeze-thaw cracking on flat rear additions. Old modified bitumen, layered without correcting drainage slopes, collects water that expands through 20-plus freeze-thaw cycles each Forest Park winter. The membrane cracks. The decking rots. We see it on nearly every bungalow tear-off.
- Ice damming at the pitched-to-flat transition. Heat escaping the house melts snow on the low-slope hip; water runs down and refreezes at the cold flat section, backing up under shingles and into interior walls. Proper transition flashing and adequate insulation are the fix, not just new shingles.
- Hidden parapet flashing failure on two-flats. Decades of re-roofing in Forest Park never addressed original or 1970s-era coping and step flashing. The field membrane looks fine. The leak’s coming from the parapet top, every time. We probe there first.
- Rotted board sheathing beneath multiple layers. Original 1×6 or 1×8 decking on 1920s structures can’t handle moisture trapped under layered roofs. Tear-offs in Forest Park routinely uncover spaced or punky boards that must be replaced before any new system goes down.

FAQs - Specialty Roofing in Forest Park
It’s almost always the transition, not the field membrane. Ice damming at the point where your pitched hip roof meets the flat rear section forces water backward under shingles and into the wall cavity. The flat roof itself may be sound. We inspect the transition flashing first, then probe the parapet coping if your structure has one. Call (855) 641-3418 and we’ll diagnose it - estimates are free.
Yes, if it’s spaced, rotted, or has been wet repeatedly. Original 1×6 or 1×8 board sheathing on Forest Park’s 80-to-110-year-old housing stock often can’t support modern membrane systems without additional structure. We photograph the deck condition during tear-off and replace only what’s necessary, at $380-$620 per square. You’ll know the full scope before we proceed.
We don’t recommend it. Forest Park’s flat additions typically have ponding water, layered membranes, and compromised decking beneath. Covering old material traps moisture and voids most manufacturer warranties. A proper tear-off lets us correct drainage slopes and replace rotted decking - the only way to get a 20-year TPO lifespan. The upfront cost is higher; the lifetime cost is lower.
Look for water stains on interior walls near the building corners, or efflorescence on exterior brick below the roofline - both indicate coping or step flashing failure, not field membrane problems. On Forest Park two-flats, this hidden flashing is the leak source more often than the flat roof itself. We probe parapet tops and interior corners on every inspection because we’ve learned where the water’s actually coming from.
A properly installed TPO roof on a Forest Park flat addition lasts 18-25 years, assuming the decking was sound at installation and drainage slopes were corrected during tear-off. The village’s 20-plus annual freeze-thaw cycles will shorten that if ponding water remains or if the transition to the pitched roof wasn’t properly detailed. Our 90-Day Done Right Promise covers the workmanship; manufacturer warranties on the TPO membrane itself run up to 20 years.
