Roof Repair for Pilsen Cottages and Two-Flats
Italianate cottages on raised basements, where the front parapet and the rear addition rarely fail together.
What goes wrong on roofs in Pilsen
Pilsen carries a distinctive 19th century building stock: Italianate and Queen Anne influenced brick cottages and two-flats, often built with a raised basement so the main floor sits well above grade, with prominent front steps. Roofs are low-slope behind parapets, frequently with decorative cornices and pressed metal detail at the front elevation. There is also a substantial stock of converted industrial and commercial buildings along the corridors and the rail lines, carrying large low-slope roof areas.
Decorative front cornices are a specific issue here: the transition from the roof membrane over and behind an ornamental cornice is a difficult detail, and when it fails, water gets into the masonry and the cornice itself. Parapet coping joints on century-old masonry are the other constant. Rear porches, common on this housing type, carry their own roof sections and their own problems.
Pilsen sits on the Lower West Side, covering 60608, so the roof detail above is specific to these blocks rather than to Chicago as a whole.

Roofing questions from Pilsen
Why do Pilsen’s decorative front cornices cause leaks?
The roof membrane has to carry water over and behind an ornamental cornice without getting into it. That detail is hard to get right, and when it fails, water gets into the masonry and the cornice itself. It needs careful work, not sealant.
What is a raised basement, and does it affect the roof?
Many Pilsen cottages and two-flats were built with a raised basement so the main floor sits well above grade, reached by prominent front steps. It does not change the roof directly, but it makes these buildings taller than they look, which affects access and setup.
Do the front and back of my Pilsen building fail differently?
Often. The decorative front cornice and parapet tend to fail at the ornament, while rear additions fail where they join the main roof. They rarely fail together, so a roofer should check both rather than assume one cause. Note when and where each leak appears, which helps them find it.
Can a damaged cornice be saved?
Often, if it is caught before the masonry behind it fails. Stopping the water at the roof-to-cornice detail is the first step. A mason may be needed for the ornament itself. Leaving it too long risks losing the detail entirely.
