Has anyone run into water pooling on an off-ridge vent before? None of the other vents (different areas of the roof) had this issue, it had just finished raining. Vent did not appear to be dented.
Off-ridge vents have a minimum slope requirement, typically 2:12, 3:12 or 4:12. I would suspect that the roof slope is below the minimum for the vent at this location.
What Brian said. Also, I usually see those installed low on homes with eaves/soffits that are not large enough for vents, not as “off ridge vents”.
Yes, in my opinion those are not installed at the right location. In the middle section of attic instead of at the lower and upper sections.
Yeah, I agree with the others. That’s got to be the wrong part for the job. Nothing on a sloped roof should allow water collection. I’d love to hear a roofer try to defend that install. I think it’s probably a case of what was on the truck that day.
I’ve never seen that style of vent before, it almost looks like an elongated box type vent.
To me it seems that box vents placed higher up on the roof would perform better than that type of vent being installed so far from the ridge.
The pooling water is an issue that I would write up.
I see these vents on homes of a certain vintage. Most of the newest passive vents are are just a low, dome type of deal.
As mentioned above…they’ve got that on the hip slope which in this case seems to be super shallow.
Oren,
Yes I’ve seen that happen a few times. Roof material and vent look newer. My guess is the roof plane has a dip or sag and/or same with the top of that vent. Good thing you showed up just after a rain eh? I don’t think that’s something we or I would catch given the newer materials!
As others have mentioned, wrong product for this application.
It’s brand new construction - these types of vents are extremely common here in Florida. Honestly this slope didn’t strike me as being too flat for this vent type but I suppose it’s possible. Will measure the slope next time if there is a next time.
Dumped a bottle of water out but don’t think it was enough to really get a good idea of where the water was going. It could be traveling left and then down, but it does almost look like it’s traveling back towards the top edge of the vent
I’ll attach the video.
The slope looks fine in the photos, and very common vent in Central Florida.
Also common is the typical dent or bow in many of them, and no, not that giant crush injury from a ladder, which is another common battle scar on these vents…
Yep. Very common around here too. And I also see them dented, or have water stains from pooling. However, I have never seen any roof leaks because of it.
Brand new house with cheap 3 tab shingles? Especially in Florida? Rarely if ever see those in my area unless it’s a very low grade track builder
Yeah, noticed that. Not my place to say anything about that though
Roofer cut a four foot hole in plywood, with no support underneath (possibly even in a joint in the plywood), causing it to sag in the middle. Would help if we had some attic photo’s in this area. JMO
Perhaps that was done purposely by the contractor to solve the pooling issue?!
(Likely can’t see it from the ground).
I just figured it was a limb as this home was under a live oak, but you make a good point.
That suggests a level of cogent thinking that’s certainly not likely to be there in these parts.
