Extra vent boot?

[John Arnold]

I could feel another boot under this one. It seems like this was added as a kind of storm collar or just a lame attempt to fix the ripped one underneath. Never seen anyone do this before.

There are four parts to the above, while all four are correct, the last one will change the next time. ;)

1) I could feel another boot under this one.
- Correct, there is another one under that one.
2) It seems like this was added as a kind of storm collar
- That is what they are attempting to use that one for.
3) or just a lame attempt to fix the ripped one underneath.
- Yes, that is just a lame attempt to fix the ripped one.
4) Never seen anyone do this before.
- You won't be able to say that the next time. :)

The sad thing is, with the way my memory is going, I probably will.

Unfortunately, that happens to all of ... what were we just talking about? :sad:

The old one is probably deteriorated if it is about 7 to 10 or more years old. However, I have thought about adding second collars or the covers made to cover vent pipes and flashing collars to protect the my flashing collars from deterioration.

The rubber collar is always split and the hard plastic flashing is always in good condition. I have cut the flat portion of the flashing off and used the rubber collar as seen in the op's pic. I think that there is a repair collar that you can buy with the flat flashing already cut off. No reason it shouldn't work and in my experience it works well.

I've seen those too, they either come without the deck flange or the people have already cut the deck flanges off. Depending on how deteriorated the original collar seal is, that type of repair may or may not be sufficient to not leak.


No reason it shouldn't work and in my experience it works well.

The main problem with the one in the photo is that the deck flange is still there.

That deck flange will catch the wind and move around, possibly damaging the new collar or something else. It will also catch the wind driven rain and guide it to where you don't want it.

I have been seeing a product lately that is new to me. Something called a "perma-boot" I am told they are available at the Lowes and Home Depot. It is a hard plastic vent stack with a swivel bottom, an adapter and some glue. I recently had a roofer demonstrate for me and the installation took less than two minutes. The roofer slipped on the vent stack, laid a bead of adhesive around the PVC plumbing pipe and snapped on the adapter to make contact with the glue. Done.

Alton,

Interesting product. :cool:

Your description matches the video of the installation as shown on their web site ( Perma-Boot :: Installation (http://www.permaboot.co/installation.html) ), however, the video does not match their installation instructions ( http://www.permaboot.co/permaboot_install_instructions.pdf ).

As seems to always be the case ... the devil is in the details (i.e., in the installation instructions), which even their installation video ignored. :(

From the installation instructions:
"1 Please note the hinge is only necessary for installation,
it provides no structural strength after the product is
in place."


"2 If your PVC pipe moves downward while installing the
boot, you may need to pull the pipe up while sliding the
boot down so that the boot stays in contact with the roof."


"3 In most areas, building code states that the PVC pipe must
be 12 inches above the roof. The Perma-Boot® can handle
a few inches of variation from this, however, modification
in pipe height may be required for some installations."

Item 1 no biggie, just explanatory; however, item 2 means that the pipe is not properly supported and secured in the attic below - and that should be addressed before continuing, otherwise the pipe could move up and down and cause a failure (although the installation instructions do not address that), and item 3 means that, under most conditions, the installation will required modification in pipe height (taller or shorter) as how many places actually enforce that requirement, and how many places have snow load which requires the pipe to be even higher.

Then there is this:
Step 2 Apply bead of adhesive on top of boot and surface between base and pivot
(disassemble at hinge to apply)

Again, not addressed in their installation video yet it is a critical requirement to seal the hinge part to the lower body part.

I have occasionally seen covers like the one in the link. I don't think it is a good cover for repair, but should lengthen the life of the flashing collar.

Mark, could you please share why you don't think this one is as good as the other? Poor mating to flashing, pipe, etc.?

[Mark Parlee]

Here is the one I see used around here.
sure makes it a lot easier than replacing the entire flashing when only the seal is bad.

Spraying the rubber boots with armor all occasionally will make them last a lot longer....

I can't get them to change air filters:confused:.

If the flashing collar is already deteriorated I don't think this one would stop wind driven rain.

Pretty simple:

X inch vent cap not installed per manufacturer requirement/code/ not installed in workman like manner.

Done
