Roof leak vs condensation
Compare liquid water entry with vapor condensing on a cold surface.
☂Roof water entry
VS◌Surface condensation
Typical location
Upper ceilings, roof penetrations, eaves and attic surfaces
Cold windows, corners, frames, pipes and poorly insulated surfaces
Timing fingerprint
Rain, wind-driven rain or thaw
Cold weather, showering, cooking or overnight occupancy
Visible or audible pattern
Localized rings, wet insulation or a path below a penetration
Diffuse droplets, wet edges or recurring surface spotting
Best separating check
Correlate moisture with weather and inspect above the mark
Record surface temperature and indoor humidity together
Evidence that weakens it
Only changes after fixture use
Direct liquid path after rain
The rule
Use this comparison in Clue Engine →Do not repair the resemblance. Verify the pathway.
Color and shape can overlap. Timing, location and a repeatable check usually carry more diagnostic weight.
