How To Know if Turtle Vents are Causing Leaks
This Doug with Far West Roofing
Today we're going to look at a turtle vent and some of the problems that a turtle vent can cause on a roof. What we're looking at, these vents that you see over here those square a called turtle back vents or turtle vents because of the shape, and their purpose is to cover a hole cut in the ply wood that allows the hot air to come up out of the attic today its about a hundred degrees Fahrenheit and i can feel the warm air coming out of this vent threw these louvers right there.
This vent a few things that just immediately draw my attention to this vent. Is you can notice how water would run backwards you can see these nails exposed nails. that nail over there in fact both are of a particular concern, but it causes is that this area of the vent that its concave that its shaped so that all that water would drain threw that hole of course in the center and then leak down into the vent a few other things that cause me some concern is this crack that we see here and when we lift this up we can see that crack crack in the shingles right there. See the cut extending way beyond the corner, another nail that's exposed right there but as we look at this just a really poor turtle vent installation job.
What we do to repair this in essence would be to remove this vent, purchase one just like it and then replace the shingles around this area put the new vent in with an ice and water shield barrier over the top flange of this vent and then put new shingles over the top. And that will solve this vent from leaking.
What you will notice as a homeowner is you will see water dripping or water damaging your ceiling. This will be in the center of a living room, usually the center of your home a place where you wouldn't expect to find water leaking. You'll notice something like that in your ceiling (a stain on the drywall or ceiling tiles) and usually that's a turtle vent like this that's causing that problem
