Nano Shield of Wisconsin | Roofing Services in Menasha, WI 54952

In our Wisconsin climate, repeated freezing and thawing cycles are the main culprit. Snow and ice expand as they freeze, putting pressure on flashing seals. When they melt, water can seep into the now-loosened seams. Over time, this cycle weakens the adhesive and fasteners, causing the flashing to lift and creating a direct path for water into your home's structure. Our repair process specifically addresses this by resecuring the flashing with materials designed to withstand our local temperature extremes.

A proper repair starts with a thorough inspection to locate all points of failure. We then carefully lift the affected flashing, clear away any old sealant or corrosion, and inspect the underlying decking for water damage. The area is dried and prepared before we resecure the flashing with corrosion-resistant fasteners and apply a high-grade, flexible sealant that remains watertight through expansion and contraction. The goal is not just a patch, but a long-term solution that addresses the root cause of the leak.

The best defense is proactive maintenance. We recommend a professional roof inspection, ideally in the late fall, to check the condition of all flashings around chimneys, vents, and valleys. Catching minor wear or loose seals before winter allows for a simple, preventative repair. For added protection, we can apply specialized sealant treatments that enhance the water-shedding ability and flexibility of your existing flashing, helping it better resist the seasonal stress that leads to leaks in Menasha.
