Water leaks around vent on the siding

Gable vent on the siding has let water inside my attic during wind-driven rain. Then it would travel down to the room below it. I have both ridge vents and soffit vents, making this gable vent unnecessary. So I blocked it off from the inside, put silicone and foam around the gap (pictured), but water still got inside. Then I did a garden hose test to let water run down the siding, because I think there’s a gap between the circular trim and the siding. Then I went to the attic and saw water on the sheathing and on bottom frame of the vent. So how do I fix this leak? Caulk around the circular trim from the outside? Or remove that trim and see if I can put some flashing around the vent? submitted by /u/lindainutah [link] [comments]
