Those black granules are a protective coating on asphalt shingles. Granule loss is common in Chicago due to thermal expansion and contraction from our temperature swings, hail, or aging shingles. While some loss over time is normal, excessive granulation exposes the asphalt mat to sun damage, leading to cracks and leaks. We recommend an inspection to assess the extent. For many homes, a repair or partial replacement can solve the issue before it leads to interior water damage.

The most frequent cause is failed sealant or flashing around the skylight frame. In Chicago, freeze-thaw cycles break down caulking and compromise metal flashing. Water then seeps under the shingles and into your home. A proper repair isn't just re-caulking; it often involves carefully removing surrounding shingles, inspecting and replacing the step flashing and counter-flashing, and integrating new waterproof underlayment. Our technicians are trained to address these specific leak paths to provide a lasting seal against our windy, wet weather.

It depends on the roof's age, the extent of damage, and the number of problem areas. For a roof under 15 years old with isolated issues like one leaking skylight or minor granule loss in a single section, a targeted repair is often the most cost-effective solution. However, if your roof is approaching 20+ years and you're experiencing widespread granule loss or multiple leaks, a full replacement is likely more economical long-term. We provide a thorough, no-obligation assessment to outline all options, helping you make the best investment for your home and Chicago's climate.
