Membrane systems
Commercial roof systems we install in Elmhurst
EPDM (Rubber)
25-35 years
Black synthetic rubber sheet — proven since the 1970s. Lower reflectivity than TPO but excellent cold-weather flexibility. Priced the same as TPO — preference call based on building orientation + climate.
TPO (Thermoplastic Polyolefin)
20-30 years
The most-installed single-ply commercial membrane in the US. White reflective surface cuts cooling loads. Seams are heat-welded — when done right, they outlast the rest of the membrane. Best default choice for warehouses, strip centers, and flat-roof residential.
Building types
Common Elmhurst commercial roof projects
Retail strip and big-box
DuPage and Cook County retail plazas. Phased re-roofs under active tenants — staging and water management matter more than the membrane choice.
Mixed-use commercial
Ground-floor retail with residential above. Roof replacement requires coordination with condo boards and tenant-occupied units below.
Hospitality and institutional
Hotels, schools, and medical facilities. Typically legacy roofs (BUR or modified bitumen) being re-roofed with TPO or EPDM.
Two-flats and greystones
Chicago's signature housing stock. Most have flat or low-slope roofs over masonry walls. Modified bitumen and TPO are the modern replacement materials.
Maintenance schedule
Preventive maintenance for Elmhurst commercial roofs
Twice yearly (spring + fall)
Walk inspection, drain and scupper clearing, seam and flashing inspection, debris removal, ponding-water check.
After any major storm
Emergency walk, photo documentation, temporary patch of any punctures or seam separations, insurance claim trigger if damage found.
Every 3-5 years
Infrared moisture survey to map wet insulation, core samples in suspected areas, seam-probing test, caulk and pitch-pan rework.
Every 10 years (mid-life)
Restoration coating (acrylic or silicone) to extend service life by 10-15 years before full replacement is needed.

FAQ
Elmhurst commercial roofing questions
What does a commercial roof replacement cost in Elmhurst, IL?
Commercial TPO or EPDM replacement in Elmhurst runs roughly $8-$14 per square foot installed depending on substrate, slope, insulation thickness, and tear-off versus re-roof. A 20,000 sq ft warehouse roof typically lands in the $160,000-$280,000 range. For a flat-roof residential section, expect $33,500 - $42,500 on a typical 2,400 sq ft home.
How long does a commercial flat roof last in Chicago?
Service life depends on the system and the maintenance program. In Chicago: TPO runs 20-30 years, EPDM 25-35 years. Documented semi-annual maintenance typically adds 4-7 years to either system by catching seam failures before they become substrate failures.
Do you offer preventive maintenance contracts for Elmhurst buildings?
Yes. We offer semi-annual inspection and maintenance contracts for Elmhurst commercial properties — two scheduled visits per year, post-storm emergency walks, written inspection reports with photos, and priority dispatch for any leaks. Standard pricing runs $0.05-$0.10 per square foot annually depending on building size and access.
TPO vs EPDM in Elmhurst — which should I specify?
TPO is the default for new construction and tear-off replacements in Chicago: white reflective surface cuts cooling loads, heat-welded seams outlast the membrane itself, and material cost is lower. EPDM is a better choice on buildings with heavy rooftop foot traffic or extreme cold (black rubber flexes better in freezes), and on older buildings where adhesive-seam tie-ins to existing flashing are cleaner than heat-welded. We'll spec based on your specific building, not vendor preference.
Can you recover over my existing Elmhurst commercial roof instead of tearing off?
If the substrate is dry, the insulation is intact, and we're inside the first recover allowance (most codes permit one), yes — a recover saves 20-40% versus a full tear-off. If the insulation is wet (infrared scan + core samples tell us) or you're already on a second recover, the math flips and tear-off is the cheaper long-term call. We do an infrared moisture survey before quoting so the recommendation is honest.
How do you coordinate install around Elmhurst tenant operations?
For occupied buildings we run evening + weekend shifts, stage materials off-hour to avoid dock conflicts, and seal each work area daily so the building stays dry and operational through a multi-week install. Pre-construction we walk the tenant plan with the building ops lead so everyone knows exactly what to expect — no surprises during a restaurant dinner rush or a retail weekend.
What's the warranty on a new TPO roof in Elmhurst?
Manufacturer TPO warranties run 20-30 years depending on membrane thickness (60mil vs 80mil) and the NDL system tier. Our 5-year workmanship warranty stacks on top and covers installation defects that cause leaks. All warranties are registered in the building owner's name at substantial completion, not ours — so if the building sells, the warranty transfers cleanly.
Does my insurance cover commercial roof replacement in Elmhurst?
Storm-damaged commercial roofs in IL are covered under standard property insurance for hail, wind, and tree-fall — same as residential. Age-related wear is not. We meet your carrier's adjuster on-site, document damage to the specificity commercial claims require (impact density per square, seam failures, fastener patterns), and file supplements when scope misses code or manufacturer requirements.
Do you pull the permit + close inspection for Elmhurst commercial work?
Yes — every permit, every inspection, every jurisdiction. We know the Chicago-area AHJs, their favored inspectors, and the specific requirements they care about (fire-rating paperwork, wind-uplift documentation, etc.). Close-out packets including as-built drawings, warranty registrations, and maintenance schedule are handed to the owner at completion.
Can you work with our existing roofer in Elmhurst?
Yes. We regularly take scope the in-house or existing contractor can't cover — large tear-offs, recovers, EPDM-to-TPO conversions, warranty-registered manufacturer work. We hand back punch-list-closed work with full documentation so the existing relationship stays intact for routine maintenance.
