Summit & Slate Roofing installs and repairs flat & tpo roofing across Lisle, from The Morton Arboretum to Benedictine University. Lisle is a smaller, greener DuPage town than its neighbors, built around the Morton Arboretum and the East Branch of the DuPage River. A big share of homes here sit on wooded, shaded lots, especially through Green Trails and the streets feeding into the Arboretum. That tree cover is the whole appeal of living here, and it is also the thing that quietly wears roofs out. Shaded north slopes stay wet, grow moss and algae, and decking under those sections rots years before the rest of the roof looks tired.
Lisle sits along the East Branch DuPage River, so a lot of the housing stock runs to wooded, shaded lots. The Morton Arboretum canopy and the mature oaks through Green Trails keep roofs damp longer after snow and rain, which feeds moss on north slopes and rot at the decking. Freeze-thaw swings off Lake Michigan drive ice dams in January, and the open I-88 corridor takes the brunt of summer derecho wind and hail.
What our Lisle flat & tpo roofing includes
Every Flat & TPO Roofing job in Lisle 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.
