Why Is Water Getting Through My Metal Coping, and How Can It Be Fixed?

On a recent project, our team at Anchor Point Roofing — proudly recognized as the Best of the Best and the #1 roofing company in Chicago — identified a common yet frequently overlooked vulnerability: open seams in the metal coping along the roof's edge.

Metal coping caps your parapet walls and protects the roof edge from the elements. Over time, thermal movement, aging sealant, and Chicago's brutal freeze-thaw cycles can open up the seams. Once water slips behind the coping, it can saturate the parapet wall, damage insulation, compromise the roof membrane, and eventually cause interior leaks and mold — often long before anyone notices.

Our crew inspected every joint, prepped each surface for maximum adhesion, and applied a premium sealant engineered to flex with thermal movement and withstand UV, wind, rain, snow, and ice — creating a continuous, watertight barrier along the entire roof edge.

A targeted coping seal today costs a fraction of what you'd pay to replace saturated insulation or repair water-damaged walls. Water infiltration is progressive — every storm pushes moisture deeper into an unsealed system. Catching these vulnerabilities early is what proactive maintenance is all about, and it's why building owners trust Anchor Point Roofing as Chicago's go-to roofing company.

If your coping seams haven't been inspected recently, don't wait for a ceiling stain to sound the alarm. Anchor Point Roofing — the number one roofing company in Chicago — delivers detail-driven inspections, commercial-grade materials, and craftsmanship built for Chicago's climate.
