How to replace a roof pipe collar, vent collar, boot — 14 Comments

  1. I like Tom Silva's method which is on YouTube. He puts a new rubber collar over the old one with tar sealant in between. Its a lot less work and just as effective.

  2. Awesome job! I need to replace mine. Where can I get one just like the one you have pictured in the video? I checked my local hardware store, but they only have the collar and I prefer to have the rubber surround at the base as well

  3. I don't think I'd have nailed the bottom of that collar tab. I would nail it up under the shingle, then put some black silicone underneath the collar tab on the bottom so it won't lift in high wind.

    Nailing the collar tab on the bottom like that just creates an exposed channel directly through your roofing to the interior.

  4. Sloppy job. The cut wasn't neat around the flange. When installing a pipe boot, the manufacturers ALWAYS insist that a flashing compound be used under the shingles to prevent water from penetrating up under and causing possible damage. If I were you, I would remake the video showing the right way to install the flange. I'm going to check your other videos and will comment if I see needed. I'm a retired building inspector just trying to help you and make life easier.
