So after weeks of back and forth with the guy next door, I just bit the bullet and paid out of pocket for a camera inspection of my sewer lateral. He'd been sending me texts for a month saying my maple trees were wrecking his line and that I owed him a chunk of the repair bill. I wanted proof either way before anyone opened thier wallet. The plumber ran the camera from my cleanout all the way to the street and guess what. My section is fine. A couple of fine root hairs near the joints but nothing structural, nothing the plumber even flagged. The real damage turned out to be further down, well past where my line ends and into his own run. And here's the kicker, the roots invading his pipe aren't from my maple at all. They traced back to a giant privet hedge he planted himself right on top of his lateral about ten years ago. Got the whole thing on video with the distance counter on screen, plus a written report from the plumbing company. Sent him copies and told him politely that the trees on my side of the fence aren't going anywhere. He wasn't thrilled but he hasn't brought up money since. Honestly if you ever get into a roots-and-sewer arguement with a neighbor, spend the couple hundred on the camera inspection first. It's way cheaper than a lawyer and nobody can argue with video footage.
Camera inspection finally settled the neighbor sewer line dispute

I dealt with something similar a few years back, but it involved drainage instead of roots. My friend had a dispute with the house on the other side of the street regarding a blocked storm drain connecting to the municipal system. They were convinced the blockage was from debris his side, but the blockage was actually past the tie-in point on his side. He finally called a company called HydroFlow and they did a flow test on the inlet. It showed zero backpressure coming from his yard, which meant the obstruction was likely in the city’s trunk line further down the street. The meter they used was an 8-inch cast iron, and they traced the problem to a sink blockage three houses down that had a major grease buildup. It was a headache, but proving where the issue actually sat saved him from paying for unnecessary repairs to his own driveway and apron. Sometimes you just need the third party to run the numbers and show you the physical reality before anyone gets emotional about ownership of the problem.
I had a dispute like this a while back, but it wasn't about roots. My neighbor insisted that the vibration from my washing machine was cracking his line, and he wanted me to shoulder the costs immediately. I didn't agree to anything til I knew exactly what was going on structurally. The initial assessment was just a standard visual check, wich wouldn't show anything serious.
I had to insist that the repair company bring in specialized gear, specifically a pull tape, not just the standard camera inspection. This helped determine if the structural integrity of the pipe itself was failing or if the damage was just localized cracking. It turned out the vibration was fine, but there was a hairline crack in the pipe segment that predated my installation. It was a manufacturing defect, totally unrelated to my appliance.
becuase of that documentation, I only paid for the neccessary repair on my side and was able to get my insurance company to cover the remainder of the structural fix. It really comes down to getting the right specialist to look at the job rather than just accepting the first diagnosis offered by the contractor.
I never had a root issue like this, but I had a similar dispute about a slow drain. My neighbor insisted the blockage started on my side of the main line, and I was realy unsure how much of the problem was actually shared between our properties. I ended up having a scope run just to isolate the problem section, even though I was worried about the cost. It turns out it wasn't roots at all, but some really heavy sludge buildup that had been inside the pipe for years.
