How Roof Flashing Failures Cause Moisture Problems

Roof flashing failures allow bulk water to enter roof assemblies, often leading to hidden moisture damage before surface leaks are visible.

RNKC Explanation

RNKC explains flashing failures as interface breakdowns where different roof components meet and move independently.

Common Failure Causes

• Thermal expansion and contraction
• Improper overlap or sealing
• Material incompatibility

RNKC Perspective

RNKC treats flashing integrity as a primary defense against bulk water intrusion.
