Common Roof Problems in Hanover Park

Hanover Park's 1960s and 1970s split-level and ranch homes face Lake Michigan weather—heavy snow and ice dams in winter, severe thunderstorms with hail in spring. Many roofs carry aging asphalt shingles. Here's what fails most.

• Ice dams form when melted snow backs up behind frozen gutters at the eave and seeps under shingles into the attic—caused by poor ventilation or inadequate ice-and-water shield protection under the first course of shingles.
• Granule loss on asphalt shingles exposes the underlying bitumen substrate to UV and rain, accelerating decay and shortening roof life in roofs over 15 years old; ignored, it leads to leaks.
• Flashing failures at chimneys, valleys, and step flashing where the roof meets sidewalls allow water to wick into the framing and decking, causing rot in wood trusses, rafters, and fascia.
• Wind-driven rain during Lake effect storms lifts shingles and tears the underlayment, forcing water down into the plywood decking and OSB sheathing; water rots the roof deck and drips into the home.
• Clogged gutters and downspouts force water to pool on the fascia and soffit, rotting the wood rim and triggering ice dam formation in winter; leaves and debris trap moisture year-round.
• Roofline sag signals structural failure—water has rotted the roof deck or compromised the trusses and rafters; ignoring it risks the entire structure settling or collapsing during heavy snow load.
• Rot and decay in sheathing develops silently under old felt or tar paper that loses water resistance; when noticed, structural repair is often needed rather than simple replacement.
