Micro Blistering & Membrane Failure Detection
When Surface Conditions Reveal Deeper Problems
How micro blistering in a coating system exposed widespread membrane failure.
Project Overview
A roofing system exhibited widespread micro blistering across the coated surface. While often attributed to surface-level issues, the extent of blistering raised concerns about underlying system integrity.
The Challenge
Micro blisters are frequently assumed to be cosmetic or caused by moisture vaporization. However, determining whether these conditions indicate deeper system failure requires advanced diagnostic testing.
The Investigation
Roof Analyzers performed a High Voltage Electronic Leak Detection sweep of the coating system to evaluate the condition of the membrane beneath the surface.
The Findings
Testing revealed that:
The micro blisters were conductive
This conductivity indicated active breaches in the membrane
There was widespread failure across the system
Significant delamination was present
Why This Matters
This case demonstrated that:
Surface conditions can indicate deeper system failures
Coating issues are not always cosmetic
Conductivity testing provides critical insight into membrane integrity
Early identification prevents progressive deterioration
Project Outcome
By identifying the true cause of the blistering, the project team was able to move forward with informed repair strategies, addressing the underlying membrane failures rather than treating surface symptoms.
Key Takeaways
Micro blistering can signal serious membrane issues
High Voltage testing reveals hidden system failures
Surface appearance alone is not a reliable indicator
Accurate diagnostics prevent improper repairs
