Common Roofing Problems in Westmont

Westmont's proximity to Lake Michigan brings heavy snow, ice dams, and severe thunderstorms that age roofing faster than national averages. Most homes here—mid-century ranches from the 1950s-60s and post-war Cape Cods—have roof decks and sheathing designed for older building codes, making them vulnerable to modern freeze-thaw cycles and wind uplift.

• Ice dams — Melting snow backs up behind frozen gutters and dams, forcing water to seep under shingles and into the attic. Ignored, water wicks into the roof deck and rafter system, causing rot and interior mold.
• Granule loss — Asphalt shingles lose protective granules from freeze-thaw cycles and hail. Once granules erode, the bitumen substrate deteriorates, shortening shingle life by years.
• Wind-damaged shingles — Lake-effect gusts lift and crack shingles, especially at the ridge cap and field course. Missing fastener coverage and compromised sealant allow water intrusion behind the shingle and into underlayment.
• Flashing failure — Step flashing where the roof meets vertical walls corrodes or peels. Chimney flashing and pipe boot sealant crack under expansion-contraction cycles, opening pathways for water into walls and the attic.
• Sagging roof deck — Decades of ponding from poor ventilation or ice dam backup cause roof decks (plywood or OSB sheathing) to settle and sag. Once sagging starts, the substrate cannot support new shingles or underlayment properly.
• Ventilation rot — Soffit vents and ridge vents get blocked by debris or ice, trapping moisture inside the attic. Rafter and truss systems rot from inside out, invisible until structural damage is severe.
• Gutter overflow and debris — Downspouts clogged with leaves fail during heavy rain, backing water onto fascia and soffit. Rot spreads quickly along the eave and into the wall frame.
