Summit & Slate Roofing installs and repairs flat & tpo roofing across Wheaton, from Cantigny Park to Cosley Zoo. Wheaton is the DuPage County seat, and its housing stock tells two stories on one roof. The streets around downtown and Wheaton College hold a lot of pre-1950 homes with steep pitches, multiple dormers, and original wood decking that is now brittle. We tear those off down to the deck, replace any rotted boards, and rebuild the system properly instead of laying a second layer over tired shingles. That older-home detail work is where a lot of bargain crews cut corners.
Wheaton sits inland in DuPage County, so it takes the full Chicago freeze-thaw swing rather than lake-moderated temps. Winters bring ice dams on the deep north-facing slopes of older Wheaton roofs, plus snow loads that stack on low-pitch additions. Summer means the derecho and straight-line wind corridor that runs the western suburbs, along with hail off fast-moving July storm cells. Spring thaw is when last winter's ice-dam leaks finally show on ceilings.
What our Wheaton flat & tpo roofing includes
Every Flat & TPO Roofing job in Wheaton 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.
