Roof vent cover

We had heavy rain last which informed me of the new roof vent installed last year leaks badly around the seal where it closes. I also have bad leaking by one window at the rear bed, so I think i will have to fill in the gutter with caulk like I did on the other side that used to leak badly. It still leaks a little but not nearly like it did.

Anyhow back to the roof vent - Basically, the foam seal they use on the 9x9 roof vent absorbs the water that splashes against it when it's closed and partly compressed. The water then manages to work it's way inside through the seal, causing drips inside the roof vent. If they had used a rubber seal instead of foam, it might not have this problem.

I had reservations about having to install a 14x14 roof vent over a 9x9 vent but that was cheaper, easier and less risky than having to cut a 14x14 hole and install a 14x14 vent into it. I had to drill into the roof to install it, but I used butyl tape and Dicor self leveling caulk to seal over/around the holes so hopefully that'll do the trick. The edges are raised up due to the butyl tape around the screws holding it down, so excess water that gets inside somehow can drain out with ease.

In a way, I had been wanting a cover over it but I wasn't going to put one if I could help it. But I couldn't. So now I have one and I like it fine. I know this will stop the leaking since I had to throw an empty plastic tote over the roof vent at 4am when it was raining badly and water was dripping in. The box used as a cover stopped the leaking. So a roof vent cover will do the same.
