Common Roof Problems in Downers Grove

Downers Grove sits in the path of Lake Michigan's winter weather system and fierce summer thunderstorms. Homes built across five decades—from turn-of-the-century Craftsman bungalows to mid-century ranches to 1980s colonials—each face different roofing stresses.

• Ice dam formation — water backs up behind frozen gutters along eaves, seeps under shingles, and wicks into attic spaces, causing rot and insulation damage.
• Wind and hail damage — spring severe thunderstorms tear shingles and dent metal flashing, exposing the substrate decking to moisture intrusion.
• Roof rot and decay — water intrusion from failed seals wicks into plywood decking, causing structural deterioration that spreads if left unaddressed.
• Flashing separation — step flashing and chimney flashing pull away from walls during freeze-thaw cycles, creating leak paths into interior walls.
• Clogged gutters and downspouts — leaves and debris dam water, forcing moisture back into fascia and soffit, leading to rot and ice backup.
• Sagging roof deck — water saturation weakens joists and rafters, dropping the roofline and creating visible interior sags or ceiling damage.
• Skylight leaks — worn sealant around skylights and pipe boots fails after repeated freeze-thaw cycles, allowing water to seep into framing.
