Common Oak Park Roof Problems

Oak Park's Lake Michigan proximity creates heavy winter snow and spring hail, while the 1890s–1920s housing stock features complex rooflines that concentrate water and debris.

Many homes have original or aging roofs nearing end-of-life, and dramatic temperature swings accelerate material failure.

• Ice dam formation — winter snow melts on sunny rooflines, then refreezes at the eave where gutters slow drainage. Water backs up behind the dam, wicks under shingles, and seeps into the attic, causing roof deck and rafter rot.
• Flashing deterioration — step flashing and counter-flashing at roof valleys and chimneys corrode or loosen from fasteners, allowing water intrusion where the roofline angles most steeply.
• Hail-driven granule loss — spring thunderstorms pelt asphalt shingles, stripping granules and exposing the bitumen substrate, which oxidizes and cracks within months.
• Ponding and membrane failure — complex hip and gable rooflines create flat valleys that pond water after heavy rain; EPDM or TPO membranes deteriorate under standing water and UV exposure.
• Wood decay in rafters and decking — moisture wicks through failing underlayment and tar paper, and frost-thaw cycles spall wood fiber, causing rafter sag and soft spots that fail under snow load.
• Wind uplift and fastener failure — spring winds peel shingles, pulling nails and exposing nail holes to water infiltration.
• Pipe boot and vent-flashing separation — roof penetrations accumulate debris and ice, and the boot flashing cracks or peels away from the substrate decking.
