Roof ventilation ridge vent leaking loose cap: What to Check and What to Do Next
A loose ridge-vent cap can admit wind-driven rain, but a ceiling stain near the ridge is not proof that the ridge vent is the source; water can travel under roof coverings, and attic moisture can also come from condensation or another penetration. From a safe location, first contain interior water, check the attic only from the access opening for wet insulation or roof-deck staining, and use ground-level binoculars to document a shifted cap, visible gap, or missing section.

Roof ventilation ridge vent leaking: What to Check and What to Do Next
Do not climb onto the roof, enter the attic, use a ladder, remove a ridge vent, apply sealant, place a tarp, or inspect during a storm. From inside the living space and from safe ground after weather clears, record where the ceiling stain appears, whether it coincides with wind-driven rain, snow or ice, whether there are signs of condensation, and whether roof debris or visible ridge-cap damage can be seen without approaching the roof.
