We use a combination of visual inspection, water testing, and infrared scanning to trace the leak to its exact source. Leaks often travel far from where water appears inside, so professional detection is critical for a permanent fix.
Intermittent leaks are common and usually caused by wind-driven rain entering from a specific direction, ice dam formation, or condensation issues. These are harder to find but our detection methods identify even occasional leak sources so we can fix them permanently.
