More Square Footage Of Flat Roof Than Anything Else
Schaumburg is a commercial town with houses attached. Between Woodfield, the office parks, the retail on Golf Road and Higgins Road and the warehouse and distribution space out toward the tollway, most of the roof area in this town is low-slope membrane. That is the work we came up doing, and it is what we do best here.

How A Flat Roof Actually Fails Around Woodfield
Commercial roofs here rarely fail across the whole field. They fail at details. Seams that were welded cold or rushed, curbs around rooftop units that were flashed by whoever installed the equipment rather than by a roofer, drains packed with debris from the parking lot trees, and pitch pans around conduit that nobody has touched since the building opened. A tenant reports a ceiling tile stain twenty feet from where the water actually got in, because on a flat roof water travels along the deck until it finds an opening.
The other thing that kills these roofs is traffic. Retail and office buildings around Woodfield have HVAC contractors, cable techs and sign installers on the roof constantly, and every one of them walks the same path from the hatch to the equipment. Membrane gets scuffed, insulation compresses into a low spot, water ponds in the depression, and a couple of freeze cycles later that ponded area is where the leak starts. When we inspect, we follow the traffic paths first because that is where the story usually is.
Warehouse and distribution buildings are their own animal. Huge uninterrupted fields, long runs between drains, and interior contents that make a leak expensive fast. On those we care about drain capacity and overflow provisions more than anything else, because a plugged primary drain on a big roof after a summer downpour puts real weight on a deck that was never designed to hold a pond. See how we approach those on the warehouse roofing page.
What We Handle In Schaumburg
- TPO installation and replacement on retail, office and industrial buildings, welded and probed rather than eyeballed.
- Commercial leak tracing where the stain inside is nowhere near the entry point on the roof.
- Commercial roof inspections with photo reports a property manager or owner can forward without translating.
- Flat roof repair and replacement on modified bitumen and older built-up systems still in service on 70s and 80s buildings.
- Shingle roof replacement on the residential side, where the subdivisions from the 70s through the 90s are cycling through now.
Restaurants get particular attention. Grease-laden exhaust, constant rooftop equipment work and no tolerance for closing the dining room make those jobs a different kind of scheduling problem. Our restaurant roof crews work nights and early mornings when that is what the job needs.
The Houses Are Not An Afterthought
The residential half of Schaumburg came in with the subdivisions that filled the town out from the 1970s through the 1990s, plus a heavy stock of townhomes and condos. Those roofs are on their second covering now, and the common problems are consistent: builder-grade three-tab shingles long past their date, ventilation that was minimal from day one, and gutters undersized for the roof area they serve. Straightforward work, but it needs to be done properly rather than blown through.
Association and townhome buildings are a regular part of that. A row of attached units means one roof serving several owners, which means a board, a scope in writing, and staging that does not close a parking lot for a week. We do those often enough to know how the meetings go. Details are on the multi-family roofing page.
Working Around A Business That Cannot Close
Nobody in a retail or office building can hand us the property for four days. So the scheduling is part of the scope. We stage material where it does not eat customer parking, sequence tear-off and dry-in so no section of roof is open overnight, and coordinate around delivery windows and store hours. On occupied office space we work the areas over unoccupied zones first when the plan allows, and we tell you honestly which days are going to be loud.
Property managers get photographs, not adjectives. Before, during and after, with locations marked, so a report can go up the chain without anybody needing to climb a ladder to understand it. If a repair is a stopgap ahead of a replacement next budget year, we say that in writing rather than selling a patch as a fix.
Warranties On Commercial Membrane, And What They Actually Cover
Owners around Woodfield ask about the twenty-year warranty on a TPO system, and the answer needs a little unpacking. A manufacturer warranty covers the membrane itself against material defect. It does not cover a seam somebody welded badly, it does not cover a curb that a mechanical contractor cut into after the fact, and most of them go void the moment an unauthorized party penetrates the roof without documenting it. That last clause is where buildings get burned, because rooftop equipment work happens constantly here and nobody thinks to tell the roofer.
What we do about it is simple. We tell you which warranty class you are actually buying, material only or a system warranty with labor, what it costs to move up, and what you have to do to keep it alive. Then we give you a written record of the install so that when a tenant’s HVAC contractor puts a new curb in three years from now, there is a paper trail showing what was there before. A roof is a building asset with a service life, and the buildings that get twenty-five years out of a twenty-year membrane are the ones where somebody kept records and cleared the drains twice a year.
Where We Come From And What The Drive Means
Our shop is in Alsip on the south side of the county, so Schaumburg is a haul. We book northwest Cook as grouped work: jobs in this corner get scheduled into the same stretch of days so crews arrive with the right membrane and equipment already loaded. A planned commercial replacement gets scheduled the way any commercial job does, with a date you can plan around. There is no travel charge for the mileage, and an active leak in an occupied building gets an emergency response regardless of what the calendar says.
Angelo Ristich runs the company, second generation, trained by his father Frank, and he walks the roof himself on commercial work rather than sending a salesman with a brochure. A+ with the BBB, HomeAdvisor Elite Service award, licensed and insured in Illinois. Residential pricing often starts on the phone from satellite measurements. Commercial scopes get a real site visit, because nobody should quote a membrane roof they have not stood on. Completed work is in the gallery.

(312) 590-4853The Neighbors On Our Northwest Schedule
When we commit equipment to this corner of Cook County, Schaumburg usually shares the week with towns a few minutes away. Hoffman Estates sits directly west along the Golf Road and Higgins corridors with the same mix of tract housing and commercial frontage, and Rolling Meadows is northeast with its ranch stock and Golf Road office strip. Batching those towns is what keeps a south-side crew practical this far out. The full territory is on the service areas page.
What Schaumburg Owners And Managers Ask
The stain in our suite is nowhere near a roof penetration. Why?
Because water on a flat roof runs along the deck until it finds a hole, which can be many feet from where it entered. We trace it properly instead of patching above the stain and hoping. That is standard on our commercial leak calls.
Can you re-roof our building without closing it?
Yes, that is the normal arrangement. We stage material off your customer parking, sequence tear-off and dry-in so nothing is open overnight, and work around delivery windows and store hours. We will also tell you upfront which days will be loud.
Our roof ponds water after every storm. Is that a problem?
Yes, especially on a big warehouse field. Ponding usually means compressed insulation under a traffic path or a drain that is not clearing. Standing water adds weight and finds seams. We check drain capacity and overflow before we talk about membrane.
Do you do TPO, or just repair what is up there?
Both. We install and replace TPO as a specialty, weld and probe the seams rather than trusting them by eye, and we also repair modified bitumen and older built-up systems still running on 70s and 80s buildings.
We are a restaurant. Can this happen outside service hours?
Yes. Nights and early mornings are normal for us on restaurant work, and we plan around grease exhaust and rooftop equipment access. Send the address and your hours through the contact page and we will build the schedule around them.
Is residential work worth your time out here?
Absolutely. The 70s through 90s subdivisions and townhome rows are steady work for us, and they ride the same northwest schedule as the commercial jobs. Same crew, same standards, torn off to the deck either way.
