Summit & Slate Roofing installs and repairs commercial roofing across Naperville, from The Naperville Riverwalk along the DuPage River to Naper Settlement. Naperville is two roofing markets in one ZIP map. East of Washington Street, the Historic District holds homes from the early 1900s, many with steep original pitches, narrow soffits, and a couple of decades of patch jobs stacked on top of each other. West toward Route 59 and 248th Avenue, subdivisions like White Eagle, Tall Grass, and Ashbury went up through the 1990s and early 2000s, and those original builder-grade 3-tab and entry architectural shingles are now hitting 25 to 30 years old all at the same time. We replace both, and the approach for each is not the same.

Naperville sits far enough inland that lake-effect snow off Lake Michigan still drops 30-plus inches a winter, and the freeze-thaw swing between January nights below zero and 40-degree thaw days drives ice dams along the long north-facing slopes common on the big subdivision homes here. Summers bring hail and the occasional derecho straight-line wind off the prairie, which lifts and creases architectural shingles on the tall, multi-gable rooflines west of Route 59.

What our Naperville commercial roofing includes

Every Commercial Roofing job in Naperville includes:

01

TPO and PVC single-ply membrane

Hot-air-welded single-ply roofs in 60 mil and 80 mil thickness, the standard for flat retail, office, and warehouse roofs in the western suburbs. White TPO reflects summer heat and cuts cooling load on south-facing Naperville buildings.

02

EPDM rubber roofing

Fully adhered or ballasted EPDM in 60 mil and 90 mil, a proven flat-roof system that handles DuPage freeze-thaw cycles well. We seam with primer and tape or factory-welded splice for buildings that need a 30-year service life.

03

Modified bitumen and built-up

Two-ply and three-ply modified bitumen for roofs with heavy foot traffic or rooftop equipment. A good fit for older Wheaton and Glen Ellyn commercial buildings that already carry an asphalt-based built-up roof.

04

Tapered insulation and drainage design

We add tapered polyiso insulation to build positive slope toward drains and eliminate the ponding that voids most membrane warranties. Proper drainage is the single biggest factor in how long a flat roof lasts in this climate.

05

Commercial roof maintenance and repair

Twice-yearly inspections, seam and flashing repair, drain clearing, and leak diagnosis for property managers and building owners. A maintenance plan catches a $400 seam fix before it becomes a $60,000 saturated-insulation tear-off.

Commercial Roofing questions from Naperville homeowners

Commercial roofing here runs $15,000 to $250,000 depending on square footage, membrane type, and whether the deck needs a full tear-off. TPO and EPDM typically land $7 to $14 per square foot installed. A 10,000 sq ft replacement usually falls between $80,000 and $140,000. Mark provides a firm written number after a core cut confirms deck condition.
TPO and EPDM both perform well in DuPage County freeze-thaw cycles. White TPO reflects summer heat and lowers cooling costs, making it popular on Naperville office and retail buildings. EPDM rubber handles extreme cold and is forgiving on irregular roofs. The right choice depends on your building, rooftop equipment, and budget, which we assess on site.
Pricing in Naperville typically runs $14,000 to $48,000 for a full replacement, set by roof size, pitch, and material. We measure from photos or on site, then send a firm written number before any work starts.
