Hello, I am getting some rain mist under the roof vent during heavy wind and rain. Sometimes I see water droplets on the underside of the vent and on the attic floor. If I caulk the O'hagan vent at there base where it rest on the lower tile, will the vent still allow proper air flow for attic ventilation?
I would recommend eliminating the vent. And not caulking it. The ugly truth is that from time to time vents leak for no rime or reason. Well rather there is a reason but there is no real solution. I have had vents that leak , but it has to do with wind driven rain, the angle of the roof, or possibly negative air pressure in the attic. In most cases it’s a freak occurrence that happens from time to time on only 1 area. Eliminating the vent is probably the correct answer.
My house has these vents. The roof appears to have a shallower angle that your example roof. The issue I have is during high wind rain and snow storms. The rain/snow is being driven under the lower and side edges of the vent. I can actually see water spraying in and accumulating on the under flange mesh and dropping into my attic insulation. This migrates to ceiling drywall. How do I fix that?
You need to either cancel the vent or replace it with something else like a dormer. I’ve had similar issues on different roofs and there is nothing you can do in my opinion.
@@RoofRepairSpecialist I just looked at pictures of dormer vent and they look more open ended than mine. What does canceling mean? Eliminating? If so, how do I vent summer heat?
Yes eliminating. I agree dormers are more open then these. Maybe a tile ridge vent is worth considering. All I know is I would prefer a hot attic over a leaky one.
These things look super flimsy and ghetto. I just got a re-roof estimate which states I need 10 of these for an additional cost of $900. After seeing this video, I think I'd rather not! Thanks for the info.
Let me know what type of vent you prefer to install on a S tile roof!
