"Fence" Around Vent

[Al and Missy]

Both of my Fantastic Vents (ca. 2002) have a professional-looking aluminum "fence" about 1" tall around them on three sides, just stuck to the vent flange with 5200 except for a angled tab on the rear that is stuck to the roof. Oddly enough the open side faces front. The fences are mounted with about 1/16 - 1/8 clearance above the vent flange, so I guess water from a normal rainfall would run under, but at 55 mph in a rainstorm, I don't think so.

I am removing at least one of the vents to re-seal it because it has been leaking for some time. Are these "fences" something that is normally done? I don't see them on the fantastic vent web site. I'm also putting fantastic vent covers over the vents so I can leave them open without worrying about rain getting in. I'd think that the cover will keep rain off of the vent well enough that the fences are superfluous.

On, or Off?

Thanks,

Al

Bump....
Sorry, subject not showing up properly in the portal list. Is it the quotes?

It's showing up in the portal view

Would it be possible to show some pictures? I think the flange you are talking about is some attempt of the PO to divert water. Certainly not part of the fantastic fan. It may have been an attempt to seal cracks in the flange base which are common.

Thanks Shelly. It's not a flange fix; the flange is fine. It is a vertical piece of aluminum about 1" tall bent in a U shape. It has three or four vertical tabs on the bottom where it it was stuck to the flange with sealant, probably 5200. It surrounded the sides and rear of the vent lid. The tabs leave about a 1/8" gap along the sides, but there is no gap at the rear. It makes little sense to me. I would have mounted it to surround the sides and front. This way it seems like it would pile up water if driving in the rain.

I got fantastic fan Ultrabreeze covers to go over the vents so I will be leaving the fence off when I reinstall them. I pulled this one (bedroom) because it was leaking pretty badly. The front center screw had corroded away the aluminum and was no longer tight and the sealant had failed. LR vent is next. Based on some stains on the wall I think it is leaking too, but not nearly as bad.

Thanks for the reply.

That is about the weirdest thing I've seen. It looks like it would actually funnel water into the vent. I wonder if it's not part of an after market vent cover like the one you are putting on?

There is no apparent way that anything would fasten to it, and it was just attached to the flange with four 1" beads of white adhesive/sealant and to the roof at the rear with one bead. I don't know what problem it was intended to solve, but both vents have one and they are both facing forward.

Oh well, they are coming off with the remount/reseal project. One down, one to go.
