Flat Roofing in Park Ridge, IL
Modified bitumen, EPDM, and TPO systems for low-slope residential additions and commercial buildings.
What this service covers
Flat roofing covers any roof under a 2:12 pitch. In Park Ridge that's almost always a low-slope addition behind a steeper front pitch — a sunroom, a kitchen bump-out, an enclosed porch — or a commercial building along Higgins, Touhy, or the Uptown blocks. The system you want depends on the deck, the drainage, and how long you plan to own the building.
We install modified bitumen, EPDM rubber, and TPO single-ply. Each has a use case. We don't push one system; we recommend based on the project.
Why it matters in Park Ridge
The most common flat-roof failure we see in Park Ridge is at the transition where the low-slope meets the steep pitch — a detail that's easy to do wrong. Water from the main roof concentrates at that wall, and an under-flashed transition leaks within a few seasons. We flash that detail with a counter-flashed apron and step combination that handles the volume.

Frequently asked questions
Which flat roof system is best for a Park Ridge home addition?
For most residential additions we recommend EPDM (10+ year practical life) or modified bitumen. TPO is generally better suited to larger commercial decks.
Can you fix ponding water on my existing flat roof?
Sometimes — with tapered insulation built into a new system, or with a roof coating that improves drainage. Existing ponding patterns often indicate a structural or drain issue that we'll diagnose first.
