Key points
- Thermal cameras see temperature, not water.
- Wet materials are often cooler because water evaporates — so they show up as cool patches.
- Patterns can be misleading — insulation gaps and drafts look similar.
- A moisture meter confirms what the camera suggests.
Where it helps
- Tracing how far water spread inside a wall
- Finding wet ceiling areas above a leak
- Checking under flooring without pulling it up
- Spotting leaks around windows and roofs
Limits
- Can’t see through metal or foil-backed materials
- Needs a temperature difference to work well
- Can’t confirm mold — only moisture patterns
Vault uses FLIR thermal imaging alongside Delmhorst and Protimeter moisture meters. See moisture meter readings explained.
