Cracks in Clay Coping Seams on Commercial Roof in Chicago – What You Need to Know

Clay coping is often used along the parapet walls of commercial buildings to protect the structure from water intrusion. Over time, exposure to harsh weather conditions, freeze-thaw cycles, and building movement can cause small cracks to form along the seams. These may seem like minor cosmetic issues, but even hairline cracks can let moisture in—leading to bigger problems like water damage, leaks inside the building, and even deterioration of the roof deck or wall assembly.

For commercial property owners in need of reliable Chicago roof repairs, Anchor Point Roofing offers targeted solutions that prevent further damage without unnecessary replacements. Our team specializes in maintaining and restoring commercial roofing systems throughout the city, including repairs to clay coping and parapet details.

When coping seam cracks are identified early and are still relatively small, one effective repair method is to apply a commercial-grade sealant or Lucas 6000. These materials are designed to seal cracks, prevent water from penetrating, and maintain the integrity of the coping system.

What is Lucas 6000?

Lucas 6000 is a high-performance, solvent-based rubber sealant that adheres exceptionally well to clay, concrete, brick, and masonry surfaces. It stays flexible over time, making it ideal for use on building components that expand and contract with temperature changes. Once applied, Lucas 6000 provides a watertight seal that helps extend the life of your commercial roof without altering the appearance of the coping.

Our approach always starts with a thorough inspection. We evaluate the extent of the cracking and assess whether sealing is sufficient or if more extensive repair work may be required. In most cases where the cracks are shallow and localized, applying Lucas 6000 or a similar commercial-grade sealant can be done quickly and affordably—with minimal disruption to your business.

At Anchor Point Roofing, we understand the unique demands of commercial roofs in Chicago. Whether you’re managing a retail space, office building, or multi-unit residential property, keeping your roof system protected from water intrusion is critical.
