How to Install Retrofit Roof Boot | Electrical Mast Example

Retrofit Electrical Mast Roofing Boot:
Installing a new roof boot on an existing electrical mast is no small task including calling the power company, disconnecting power lines, and install a new boot around the existing mast with the cap removed. This is pretty much not possible in a reasonable amount of time and as such there are retrofit boots that make this job much easy and result in a high-quality seal. I will walk you through an example showing start to finish installing a Zip-Seal that can fit pipes up to 4 1/2″ in diameter.

    You shouldn’t nail the front side of the boot ever. Plumbing and electrical boots are designed to work like a shingle in that only the top gets nailed that will be covered by the shingle above. By nailing the bottom you are only creating a possible leak

    I noticed a rust colored stain in a small area on the ceiling. The house was a little more than 10 yr old, so I never considered that a roof boot had been compromised …………. but that was the problem. I’m a lazy homeowner. Your videos help me learn the things that I need to look for. Thanks!

    Mine is just like this one. Cracked on top and not even adhered on bottom. My soffit above the meter is starting to rot.

  13. Michael Nance on August 18, 2022 at 2:32 am

    I appreciate the video. Great info. The only think I would have don’t different is I would have put a bead of caulk down the left and right sides and not put the 4 nails at the bottom.

    Can those boots be easily opened and re-closed?

  15. Kommon Cents on August 18, 2022 at 2:35 am

    I had a leak from a sink stack all the way to the basement, boot looked fine but I ended up putting roof cement all around the boot on the roof. 2 days later we had 2-3 inches of rain, no leaks anymore.

  16. Duke Frywokker on August 18, 2022 at 2:38 am

    Don’t you have to seal the cutout for the pipe too? I would think it would be a good idea to throw some sealant around the pipe there, but I’m not a roofer either, lol.

    Sir I enjoy your tutorial videos…it helps me a lot without being a pro…I’m good at observing and working with my hands.

  18. garbo on August 18, 2022 at 2:44 am

    Just add a little silicone. Will be good for another 6 months.

  19. Jim Bohnenkamp on August 18, 2022 at 2:44 am

    I used a product that covers the existing boot and all. I can’t remember the name, but it’s supposed to last as long as you own your building. I had it re-roofed three years ago, and the roofers just left it as it was before. I feel secure with it.

  20. Doak 48 on August 18, 2022 at 2:45 am

    Never seen those before. Thanks.

  21. CoachBob Barnes on August 18, 2022 at 2:45 am

    Yikes, the electrical mast? My only advice to any DIYer would be to stay away and call a pro, or indeed get the utility to cut the power from the transformer on their pole.
    Don’t be the shortcut for the power company to find ground! Your heart cannot handle it.
    I’m glad you got through this ok. The ladder up to the base of the mast likely kept you out of trouble. But if this were to require putting your whole body on the roof to get the job done, sorry, no, you’re too close to bzzzzt, please stay away!

  22. b. west on August 18, 2022 at 2:48 am

    I would have put some sealant on the edges of the boot, too.

  23. Jason Ward on August 18, 2022 at 2:52 am

    Good job ,but you made a mistake, but u never nail on the bottom instead use silcone. In five years those nails gonna rust and the pipe is gonna come loose.

  24. Jeff Reidy on August 18, 2022 at 2:54 am

    Good video Scott. Many people don’t realize that the rubber boots dot last for the life of your roof shingles

  25. Horace Rumpole on August 18, 2022 at 2:55 am

    Good workmanlike job-

  26. Sylvester Folks on August 18, 2022 at 2:59 am

    Were do you purchase the claps. I ordered the boot but the claps did not come with it.

  27. David Kahler on August 18, 2022 at 2:59 am

    It would be so luxurious as a buyer to be able to demand something be fixed! 😆

  28. Shignila on August 18, 2022 at 3:00 am

    Slow down at certain parts (removing shingles, applying sealant) and show us exactly what u are doing plz

  29. mabell3yah on August 18, 2022 at 3:00 am

    Nice trick! That boot looks really useful, but at $70 I’m definitely going to measure twice and cut once.
