C & M Roofing & Sealcoating - Chicago's Experienced Roof Repair

Common signs include sagging roof lines, dark stains or streaks on your interior ceilings, a musty odor in your attic, and spongy or soft spots you can feel from the attic floor. In Chicago, rot often starts where ice dams form or where snow accumulates, trapping moisture against the wood. If you notice any of these issues, it's crucial to have a professional inspection to assess the extent of the damage and prevent further structural problems.

Chicago's freeze-thaw cycles, road salt aerosols, and lake-effect moisture accelerate metal flashing corrosion. Corroded flashing loses its waterproof seal, leading to leaks around chimneys, vents, and skylights. We fix this by carefully removing the old, compromised flashing, preparing the surface, and installing new, high-grade aluminum or galvanized steel flashing sealed with durable, flexible cement. Proper installation is key to creating a long-lasting barrier against Chicago's elements.

In many cases, we can perform a targeted repair by removing the damaged shingles, cutting out the rotted decking section, and replacing it with new, treated plywood or OSB. We then re-install the underlayment and shingles to match your existing roof. A full replacement is only necessary if the rot is widespread or the roof is near the end of its lifespan. We'll provide a honest assessment and recommend the most cost-effective solution for your Chicago home.
