Perma Boot 312-4 BLK Repair Plumbing Vent Boot Repair System, 4-Inch Fits 4-Inch PVC Pipes, Black

Easy to install and does the job. My plumbing roof vent had a large crack in the boot above the flashing. I slipped the Perma Boot over it with ease and was done. I chose to add some sealant around the top 3/4 of the boot but it's not required. Looks nice and seems to be working well. We've had several big storms since adding this and no leaks.

I'm so happy I found this thing, was replacing cast vent and tore boot on roof. Contractor told me would have to pull up some shingles and replace the boot, was going to cost couple hundred dollars. purchased this thing and it fit right on, looks good, covers the white pipe as black and didn't have to replace the boot. Installed using no tools and has been installed for over a month through storms and hasn't moved and no leaks. Highly recommend for both contractors and DIYers.

These boots are relatively easy to install. So far working great!

These American made , roof plumbing vent covers are awesome. Never replace another rubber boot cover again for the life of your roof. Durable , easy to install , and you don't need to disturb your existing shingles. Customer service ( Sales Manager) answered any e-mailed questions I had within 24 hours. Great company. Great product.

It's a perfect fit over 4 inch pvc. Had to cut down the length of the pipe some and modify the grate I was using. This product is awesome and great for preventive maintenance. A must buy.

Super easy. Just make sure you measure and order the right size. And buy caulk.Learned about this in my home inspector training class after my teacher raved about it. There was no way i was replacing my slightly cracked and leaking boot without wrecking my old but intact shingles. This is the perfect safe alternative, and will cover all future cracks.

I purchased this product to repair an older cast iron sewer vent flashing that was leaking. Thinking it might be simple, I climbed up the 20 some feet with my box of stuff, to install the Perma Boot cap. I had replaced the original vent flashing with a new rubber collar previously, and the fact that it was still leaking made me think I that I might need to repair around the old vent flashing, so I did all sorts of fixing... new counter flashing, replacing loose bottom nails, regluing disturbed shingles, and then set the Perma Boot unit on the original vent for a see if it would work. It seemed fine, so I caulked it in place, and caulked the the top piece on. As I normally do in a case where I want to not have to come back, I re-studied the new vent. I realized that the new top cap part was about 4-5 inches away from sitting directly on the original cast iron vent pipe.The top replacement vent piece, I assume, is supposed to fit down over the vent pipe, preventing water from getting anywhere but the inside of the vent pipe. With a 5" separation between the new flanged top, and my sewer vent, I surmised that rain could just come in at an angle an run right down the outside of the old vent, giving me the same problem of seepage I was trying to fix. I've had some problems sawing plastics in the past, and I decided against getting adhesive junk all over me, trying to saw the new repair pieces to fit. So I made an interior funnel type flashing out of some spare aluminum and made sure it sat tightly under the new top cap flange and funnel into the vent stack. Now, hopefully rainwater will run down the inside of the aluminum flashing and into the vent pipe, and not trickle down the outside. An adjustable length adapter for iron pipe might be a good accessory item. I also think the instructions should mention that the height of the original vent pipe needs to be a good fit with the new top piece. The instructions avoid giving advice about caulk types, and really don't give any (look for this, or that, check for) installation tips. Since this product is made for the casual repair, a little help could do wonders. As an aging general contractor, I've done a lot of building. Roofing problems are one of the most aggravating and perplexing repairs to fix. I'd also like to know if this product can be used in high wind areas.

Excellent product and easy to install. Make sure you measure the inner diameter of you vent pipe though to order the correct unit.I also recommend that I’d tou live in a high snow area that you seal the joints to insure now water will find its way through the installation seams.
