What We Install

Commercial Roof Systems We Work With

We install, repair, and maintain the full range of flat and low-slope commercial systems — and we weld seams and fabricate the metal details in-house rather than subcontracting the critical work.

What We Do

What We Do for Commercial Properties

New Roofs & Full Replacement

Complete commercial roof installation and full tear-off replacement, specified to your building and how long you plan to hold it.

Repair & Leak Detection

Targeted commercial roof repair and leak tracing — we find the real source and fix it, including the flashing and seam work most crews skip.

Restoration & Coatings

Reflective restoration coatings that extend roof life and cut cooling load — years of added service at a fraction of replacement cost.

Maintenance Programs

Scheduled inspections and preventive maintenance that catch open seams, clogged drains, and failing flashing before they become shutdowns.

Storm & Insurance Work

Storm and hail damage repair with full photo documentation and the written estimate your insurer needs — based on the actual damage.

Emergency Response

Fast emergency response and temporary weatherproofing to stop active water intrusion and protect your building and tenants.

Local Context

Commercial Roofing Built for Downers Grove Properties

Downers Grove is one of DuPage County’s busier commercial markets — a walkable downtown business district near the train, retail and office along Ogden and Butterfield, and a substantial base of corporate office and light-industrial space near the I-88 corridor. Most of those buildings run on flat and low-slope roofs, where the seams, drains, and flashing are the first to fail. The full Chicagoland cycle — snow load, freeze-thaw, ponding after storms, and hail — keeps finding the weak spots. When a membrane fails over leased space, downtime and water damage follow. We travel to Downers Grove to keep those roofs watertight.

FAQ

Common Questions

Do you handle commercial roofing in Downers Grove?

Yes — we regularly take commercial work in Downers Grove and the surrounding DuPage communities from our Arlington Heights base. Call (877) 850-5292 and we’ll get out to assess your roof.

What commercial roof systems do you install?

We install and service TPO, PVC, EPDM, modified bitumen, built-up roofing, and metal systems. We’ll recommend the right system for your building, budget, and hold period — and fabricate the metal details in-house.

Can you repair or restore our roof instead of replacing it?

Often, yes. If the membrane has life left, a targeted repair or a restoration coating can extend it for years at a fraction of replacement cost. We’ll tell you honestly which is the better value.

Will the work disrupt our business or tenants?

We schedule around your operating hours and tenant access, keep the site clean and safe, and coordinate the work to minimize downtime. Most commercial work is done with the business still running.

Do you offer maintenance programs and handle insurance documentation?

Yes to both. Scheduled inspections catch open seams, clogged drains, and failing flashing before they become shutdowns. For storm damage, we document everything with photos and provide the written estimate your insurer needs.
