Summit & Slate Roofing installs and repairs commercial 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 commercial roofing includes
Every Commercial Roofing job in Lisle includes:
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.
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.
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.
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.
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.
