Video
A 20-second video with a date beats a remembered drip.
Investigators and adjusters can use a clip that shows where water is coming from and whether it is still moving. Heroes standing under a bowing ceiling do not help.
Film wide, then closer, from a safe place.
Include a fixture or a room landmark.
Say the time out loud if the camera does not stamp it.
Phones differ.
Stop filming and leave if the ceiling is coming down.
You already have enough.
Questions people ask
Is video better than photos?
Video shows motion. Photos show detail. Both are useful. Neither replaces a visit.
Should I live-stream the leak?
No. Send a short clip to the manager. Do not perform.
