Md Roofing Services: Pipe Collar Repair on Roof in Bowie, MD
1. First, the existing shingles being removed are cut just above the “keyways” with a hook blade knife, then the roofing nails are carefully removed so as not to tear the shingles. 2. Next, the nails on the leaking plastic pipe collar are removed with a pry bar — then the collar itself is removed. 3. After cleaning the surface and installing two new base shingles, the new collar is placed over the PVC pipe and secured with 1-1/4″ roofing nails. 4. A sealing bead of Geocel Tripolymer Sealant is placed in a circular ark around the collar as an added barrier to water and wind driven rain. 5. New Certainteed XT25 shingles are properly cut and nailed into place. 6. Shingle tabs are sealed with Geocel to prevent leaks and “blow offs”. Note: The replacement shingles installed by www.HomeRestorationsMD.com look slightly “off color” due to the packing material used in the manufacturing process; one light rain and the shingles will match the old ones almost perfectly.

Thanks for the good words, Ponch. Yes, it can be a real hassle trying to find someone that can replace pipe collars on their roof correctly.

Any ideas how I could fix the pipe collar on an electrical riser without disconnecting the power? The upper portion of the rubber has a BIG hole. I was thinking of cutting a collar at the bottom with tin snips and laying it on top of the old collar. Then maybe laying rubber from another collar under the split and using a tripolymer sealant. A roofer suggested filling the hole with MP-1 sealant. Otherwise we need an electrician.

If it looks good and it doesn’t leak, it’s been done correctly. Time/labor is too expensive for me to do them this way, but it works! I have learned to peel the rubber boot off the aluminum, cut the o-ring off the bottom, then slid it down over the original cracked leaking boot. I can redo a whole house in under 5 minutes of being on the roof. That really cuts down on our labor costs/adds to the profit. And it still looks good and it doesn’t leak.

Thanks for replying, Johnny.
I understand the labor cost issues, but I’ve been called to repair pipe collars that have been repaired this way. It seems some roof repair guys don’t pay attention to where the flange integrates with the shingles (especially on the plastic units) and sometimes overlook issues like cracking, cracked shingles, etc.
Be careful out there; one “callback” would be a lot more expensive and damaging to your reputation than $50 to $100 for labor to replace the whole unit.

I don’t know if you showed it but where you had to pop the old shingles up so you could get to the nails holding the ones you removed. did you reseal them with the caulk because usually if it’s an older roof they won’t reseal that well or at all causing a tab blow off.

@coldsud17 That’s a great observation, and very important. Yes, in addition to sealing around the pipe collar (to prevent wind driven rain from being forced under the shingles on the slick metal surface of the pipe collar) with Geocel Tripolymer Sealant — I always put a “quarter size” application under old shingles that have been lifted up too.
Location of the Geocel is about one inch up from the bottom of the tab, right in the center.
Thanks!

@Hunkerbunker346 Thanks very much for watching and taking the time to comment on the roofing pipe collar video. Truly appreciated. And it’s true about roofing techniques — “there is more than one way to sking a cat”.
I also agree that there’s no other job I would rather be doing as well.

it’s nice seeing someone put up a video of something that they actually know how to do – i’ve seen some where your average joe homeowner could do a better job, and yet they still put up a video telling people thats the way to do it- nice job and thanks for posting.

@friendlyroofer … or, if he doesn’t want to do the work himself, or he doesn’t want to take the safety risks, he now has the information he needs to hire a good roofing contractor that will give him some “peace of mind” …
“Food” for thought,

I don’t get too impressed with the DIY crap on youtube lately, but this was a bit of a change for once. This guy knows what he’s doing. Wish you were in my neck of the woods, bud. Peace.
