How IKO Products Fail - and How We Fix Them

• IKO TorchFlex SA Cap sheets separating at seams on South Side two-flats. The self-adhering cap layer loses bond strength after repeated Chicago freeze-thaw cycles, especially where afternoon sun hits brick walls and radiates heat back onto the membrane edge. We cut back to sound substrate, re-prime with IKO-compatible asphalt primer, and heat-weld new cap sheet rather than relying on factory adhesive alone.
• IKO UltraTPO punctures and hail dimpling in West Loop rooftop mechanical areas. TPO’s reflective surface hides impact damage until leaks reach the deck below; HVAC service traffic compounds the problem. Our techs photo-document every square foot, patch with matching 60-mil IKO-recommended TPO material, and weld seams with automatic hot-air equipment, not hand-held units that leave cold spots.
• IKO DuraEPDM shrinkage pulling flashings loose on North Side frame bungalows. Black EPDM absorbs heat, accelerates curing, and shrinks toward its center after 12-15 Chicago summers, tearing at pipe boots and parapet corners. We replace the affected field membrane, install pressure-sensitive termination bars with proper expansion gaps, and never caulk over a shrinking sheet expecting it to hold.
• IKO modified bitumen alligatoring on low-slope additions in Jefferson Park and Portage Park. The SBS or APP top surface oxidizes when ponding water sits for days after heavy spring rains; factory granules wash into drains and expose bare asphalt. We grind to stable base, apply a new IKO-compatible modified cap sheet, and correct the slope with tapered insulation if the structure allows.
• IKO built-up roofing (BUR) blisters and fishmouths on vintage Hyde Park greystones. Trapped moisture from interior humidity migrates upward through plaster ceilings and condenses between plies during January cold snaps. We slit and dry individual blisters, re-cement with hot asphalt at proper pour temperature, and add a vented base sheet where the existing system lacks breathing room.

Our IKO Specialty Roofing Process

1. 1
   You call, a person answers. No voicemail tree. We schedule within 24 hours for active leaks; 48 hours for non-urgent assessments anywhere in Chicago city limits.
2. 2
   Uniformed, background-checked technician arrives with a camera. Pete Callahan insists on this standard because a homeowner cannot climb up to verify our findings. Every photo is yours to keep.
3. 3
   Diagnosis with IKO-specific parts identification. We determine whether your system needs OEM IKO membrane, a quality aftermarket equivalent that meets original spec, or hybrid repair. We explain the trade-off and let you decide.
4. 4
   Written estimate with upfront pricing. The number on the page is the number on the invoice. No “while we were up there” additions.
5. 5
   Repair or replacement in one visit when possible. Most IKO specialty repairs carry enough common parts to finish same-day. Larger jobs are scheduled promptly with weather contingency built in.
6. 6
   Final walk and 90-Day Done Right Promise activation. We test drains, inspect seams, and leave the site cleaner than we found it. If something is not right, we make it right. No paperwork, no arguing.

Why Chicago Homeowners Call Ridgeline Roofing Co. of Chicago for IKO Work

We have been on Chicago roofs since 1984. Pete Callahan started this company after learning the trade at Richard J. Daley College, and we have outlasted every storm-chasing operation that blew through town with out-of-state plates. Our techs know IKO systems because they have repaired them in Lincoln Park coach houses, Chatham bungalows, and Wicker Park three-flats - not because they watched a training video last week.

The 90-Day Done Right Promise means if our weld fails or our seam lifts, we come back. No forms to mail, no manager to escalate. We also install GAF, Owens Corning, and CertainTeed systems, so when an IKO product has reached true end-of-life, we can recommend the right replacement without pushing whatever brand we happen to stock.

Live phones, uniformed crews, photo documentation, and a founder who still checks job sites. A roof doesn’t need to be impressive. It needs to hold.
