Why Ferguson Homes Are Vulnerable to Flashing Failure
Ferguson’s location in north St. Louis County exposes homes to specific weather patterns. We get more freeze-thaw cycles than areas closer to the river, causing flashing materials to expand and contract repeatedly. This movement breaks down sealants and creates gaps over time.
Many Ferguson homes built in the 1950s-1970s used thinner gauge metal for flashing that’s now deteriorating. The area’s clay soil also causes foundation shifts that can misalign roof structures, putting extra stress on flashing connections. Homes near Coldwater Creek may experience higher humidity levels that accelerate metal corrosion.
Recent storms have shown that homes with original flashing from the 1980s or earlier are particularly vulnerable. The combination of age, material quality, and our climate creates a perfect storm for flashing failure. Fixing Wind and Storm Damage Before It Ruins Your St. Louis Home.

Preventing Future Flashing Problems
Annual roof inspections catch flashing issues before they cause interior damage. We check all sealants, look for rust or deterioration, and ensure all connections remain watertight. Homes near trees need more frequent inspections since falling branches can damage flashing.

Consider upgrading to copper flashing when replacing your roof. While more expensive initially, copper flashing can last 50+ years in our climate versus 15-20 for galvanized steel.
Frequently Asked Questions
How long should roof flashing last in Ferguson?
