Common Roofing Problems in Naperville

Naperville's winter snowmelt, combined with aging asphalt shingle roofing on 1980s-1990s colonials, creates a perfect storm for ice dams, water intrusion, and premature granule loss. The DuPage River humidity and spring thunderstorms bring heavy hail and wind that peel shingles, crack valleys, and separate flashing from the roof deck.

• Ice dams — frozen gutters trap meltwater behind ridge cap areas, forcing seepage under shingles and through soffit vents into attic insulation and rafters.
• Granule loss and shingle curling — UV exposure and freeze-thaw cycles erode architectural and three-tab asphalt shingles, causing edge-curl and losing protective granules. This accelerates rot in the underlying roofing felt and plywood or OSB deck substrate.
• Flashing failures at chimneys and step flashing — sealant and caulk degrade in Naperville's temperature swings, allowing water to wick through counter-flashing gaps and saturate roof decking around dormers and vents.
• Sagging roof decks and rafter sag — standing water (ponding) on flat valley sections, combined with delayed repairs, rots the OSB or plywood substrate and causes structural settlement.
• Gutter failures and downspout separation — ice buildup and debris clogging force water onto fascia and soffit, causing wood rot and water intrusion into the walls and attic rim joist.
• Wind uplift and missing shingles — spring and late-fall storms tear shingles from the field course and expose the underlayment and ice-and-water shield, leading to rapid water penetration.
• Soffit and fascia decay — standing water from failed gutters and clogged downspouts seeps behind soffit vents and fascia boards, causing wood rot and attracting moisture into the attic rim joist and wall cavity.
