Roof louvers and vents allow proper air circulation in the attic. During severe weather, wind-driven rain or blowing snow may enter the attic through these openings. This is a known characteristic of roof vents and not considered a defect.
If moisture enters your home through a roof vent, it may show up as a spot on the ceiling. Monitor the spot during normal rainfalls/precipitation events to confirm that there is not a leak. If you suspect the spot is more than normal moisture from the vents and there may be a leak, contact us.
