Wind-driven rain: finding envelope leaks after the storm passes

The leaks that appear only in wind-driven rain are the hardest to prove and the easiest to misdiagnose — water enters at a windward joint, travels, and stains a ceiling two rooms from the entry point, then vanishes in dry weather. After a storm with strong wind, walk the windward side first: window and door seals, siding joints, flashing, and the rooms directly inside them, while the evidence is still damp. Photograph moisture-meter readings with the wall in frame; a dry-weather 'no leak found' work order convinces nobody at the next inspection. How does your team document storm-only leaks so the fix targets the entry, not the stain? — Admin
