Common Roofing Problems in Bolingbrook

Bolingbrook's severe winters and mix of 1970s ranch homes through newer colonial subdivisions create specific roofing challenges. Lake effect snow from Lake Michigan, ice dam formation in gutters, and spring hail storms combine with aging structures to produce failures that escalate quickly.

• Ice dams — water backs up behind frozen gutters in winter, seeping through underlayment and ice-and-water shield into the attic, causing rot in rafters, joists, and insulation that requires tear-off repair.
• Granule loss from hail — severe thunderstorms erode protective granules from asphalt shingles, exposing the bitumen substrate to UV degradation and water intrusion through microscopic cracks in the matrix.
• Step flashing failure — where the roof meets a vertical wall, step flashing between the roofing and counter-flashing deteriorates, allowing water to wick into rim board and joist causing structural decay.
• Sagging roof deck — older 1970s-1980s homes with shallow roof pitch accumulate winter snow load, settling plywood sheathing and cracking ring-shank nails that weaken the entire frame.
• Gutter separation and overflow — gutters pull away from the fascia and downspouts clog with debris, forcing water to cascade down walls and pool near the foundation.
• Ridge cap and vent boot deterioration — end-of-life wear on ridge caps and pipe boots around vents allows wind-driven rain to seep into the attic and rot rafter tails and decking.
• Valley flashing damage — the valley is where two roof planes meet and concentrate water flow; cracked or deteriorated valley flashing causes seepage into walls and attic spaces.
