High Voltage Electronic Leak Detection
Comprehensive dry testing of the entire roof assembly to identify penetration-type anomalies and membrane deficiencies.
High Voltage Electronic Leak Detection (HV)
Roof Analyzers begins High Voltage testing with a full electronic sweep of the entire roof assembly. This process is designed to locate most—often all—penetration-type anomalies, including breaches that are not visible during standard visual inspections.
Utilizing voltages ranging from approximately 3,500 to 36,000 volts, High Voltage Electronic Leak Detection (HV) is a non-destructive dry testing method that identifies membrane discontinuities, punctures, thin areas, and hidden defects across seamless roofing systems. Because HV testing does not introduce moisture into the assembly, any identified repairs are typically straightforward to complete, allowing for efficient remediation and minimal disruption.
What High Voltage Testing Detects
A comprehensive HV sweep can identify:
Penetration-type membrane breaches
Punctures and mechanical damage
Thin or compromised membrane areas
Installation deficiencies
Defects not visible to the naked eye
This method allows for precise isolation of anomalies before they evolve into larger moisture intrusion events.
Why High Voltage is Effective
High Voltage testing works by applying an electrical potential across the membrane surface. When the current encounters a breach, it completes a circuit through the conductive substrate below, pinpointing the exact location of the discontinuity.
Key advantages include:
Dry, non-destructive methodology
Accurate full-assembly testing
Detection of concealed defects
Efficient repair coordination
Supports quality assurance and warranty validation
Because it is a dry test, repairs can often be completed immediately following identification without waiting for system drying or additional invasive investigation.
