Common Roofing Problems in Berwyn

Berwyn's early-1900s brick bungalows and 1920s two-story homes face intense winter weather: lake-effect snow from Lake Michigan creates heavy loading on pitched roofs, and freeze-thaw cycles cause ice dams at gutters and roof edges. When ice dams form, meltwater backs up under shingles and underlayment, wicking into attic insulation and wood decking below.

• Ice dams at eaves — frozen gutters trap meltwater, which seeps under asphalt shingles and ice-and-water shield, reaching attic insulation and causing rot in decking and rafter ends if not removed promptly.
• Flashing failure — step flashing where roofline meets walls and chimney flashing corrode from salt spray and freeze-thaw stress; water wicks past missing or deteriorated sealant, entering walls and attic cavities.
• Shingle granule loss — freeze-thaw cycles and hail impact from spring storms knock granules off asphalt shingles, exposing the bitumen layer to UV degradation and accelerating end-of-life wear.
• Gutter and drip edge problems — improper slope and ice buildup prevent water from flowing to downspouts; standing water backs up and seeps under fascia and soffit into wall cavities and attic spaces.
• Roof deck rot and mold — prolonged moisture from leaks and poor ventilation causes wood decking and rafter ends to rot; attic mold follows if roof vents are blocked by snow or ice.
• Valley ice buildup — valleys collect snow and ice; water wicks laterally under shingles toward the interior once thaw begins, often reaching inside walls before visible damage appears.
• Soffit and ridge vent blockage — snow accumulation and ice buildup block ventilation ports, trapping attic moisture and accelerating deterioration of framing, underlayment, and sheathing.
