Answer: On a typical HO-3, interior rain is paid when wind or hail first damaged the roof or wall and created an opening the rain used. Rain that entered an intact ridge vent, window gasket, or worn flashing — with no storm-created breach — is the exclusion carriers cite as wind-driven rain. Coverage is the policy and the facts, not a slogan.

A shingle that lifted and laid back down can still be a broken sealant strip. That is a fact question with photos, not a courtroom script. NOAA / local wind at the time of loss supports timing; it does not replace the opening.
Texas notice clocks: see §542.056 and §542.060 desks. Do not wait on a roof argument to dry the interior.
