Flat Roof Leak During a Dry Spell — Is That Even Possible?
Yes, and it usually points to something other than rainwater intrusion — condensation, plumbing, or irrigation.
If there’s genuinely been no rain and you’re still seeing new water damage, the roof might not be the source at all. Condensation from poor attic ventilation, a plumbing leak that happens to be near the roofline, or even irrigation water finding its way into a wall cavity can all mimic a roof leak.
This is worth ruling in or out early, since fixing the roof when the actual source is a bathroom vent stack or a plumbing line wastes time and money. A proper inspection considers the whole picture, not just the roof in isolation.
