In our climate, flashing—the metal strips sealing roof joints—is constantly exposed to moisture, freeze-thaw cycles, and road salt in the air. This accelerates corrosion, especially around chimneys, vents, and valleys. Once compromised, it allows water to seep in, a problem that often becomes apparent during spring snow melts. Our repair process involves a detailed inspection to locate all corrosion points and replace the flashing with high-quality, weather-resistant materials to create a lasting seal.

Leaks from corroded flashing often appear as water stains on interior walls or ceilings near roof protrusions like chimneys or plumbing vents. If you notice dampness or staining that emerges or worsens as the snow melts, flashing is a likely culprit. However, ice dams and compromised shingles can cause similar issues. The safest approach is a professional inspection from our New Berlin team. We can pinpoint the exact source of the leak and recommend the most effective, targeted repair.

Our prevention strategy starts with using superior, corrosion-resistant metals like aluminum or copper for flashing replacements. We ensure precise installation with proper overlaps and secure fastening to prevent wind uplift and water penetration. For a comprehensive solution, we also inspect and address the surrounding roof components, such as sealants and shingle alignment, to create a unified defense system. This proactive approach helps your roof withstand New Berlin's harsh winters and wet springs for years to come.
