Boyle Roofing Company | Professional Roofing Services in Chicago, IL

Chicago's climate is particularly tough on roof flashing. The constant cycle of freezing temperatures, snow accumulation, and thawing can cause metal flashing to expand and contract, leading to cracks, separation, and corrosion over time. This is especially true around chimneys, vents, and skylights where water is most likely to penetrate if the flashing fails.

The most common signs of flashing failure in your Chicago home are water stains on interior ceilings or walls, especially after a storm or snowmelt. You might also notice damp spots in your attic, visible rust or gaps in the metal flashing from the ground, or missing sealant around roof penetrations. If you see any of these, it's time for a professional inspection.

Our process starts with a detailed inspection to assess the extent of the corrosion or damage. We then carefully remove the compromised flashing, prepare the underlying surface, and install new, high-quality flashing material—often using more durable metals or coatings suited for Chicago weather. We ensure a watertight seal with proper integration into your existing shingles and roofing system to prevent future leaks.
