Summit & Slate Roofing installs and repairs flat & tpo 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 flat & tpo roofing includes
Every Flat & TPO Roofing job in Naperville includes:
60-mil TPO membrane installation
We install 60-mil TPO as our standard, not the thinner 45-mil builders use to cut cost. The extra thickness handles foot traffic, hail, and ladder contact far better, and it carries a longer manufacturer material warranty on top of our 25-year workmanship coverage.
Hot-air welded seams
Every TPO seam is welded with a robotic or hand hot-air welder so the sheets fuse into one continuous surface. Welded seams are the single biggest difference between a flat roof that lasts and one that leaks. We never rely on seam tape or adhesive at the laps.
Tear-off of failed EPDM and built-up tar
We remove old rubber, tar-and-gravel, and mod-bit roofs down to the deck, replace any rotted sheathing, and check the slope before the new membrane goes on. Layering TPO over a failing roof traps moisture and voids warranties, so we tear off.
Tapered insulation and proper drainage
Standing water is the enemy of any flat roof. On dead-flat decks we add tapered polyiso insulation to build positive slope toward drains or scuppers, raising the R-value at the same time. This stops the ponding that shortens membrane life on Wheaton low-slope additions.
Flashing, curbs, and penetration detailing
Skylights, HVAC curbs, vent pipes, and wall transitions are where flat roofs leak first. We flash every penetration with TPO-coated metal and pre-molded boots, then weld them into the field membrane so there is no exposed sealant doing the work alone.
