Had to deal with this at one of my rentals last year—roots had basically woven themselves through every joint in the old clay line. Tried the foaming stuff, but it just bought me a couple months. Ended up replacing with PVC too. Not cheap, but way less hassle long-term. Funny how those roots keep coming even after you think you’ve got it handled... nature doesn’t quit.
PVC is the way to go, hands down. Those old clay pipes are basically an open invitation for roots—doesn’t matter how many times you snake or foam, they just find their way back in. I’ve seen folks try to save a few bucks patching or treating, but honestly, you’re just kicking the can down the road. Once you swap to PVC, it’s like night and day. Sure, the upfront cost stings a bit, but you’re saving yourself a ton of headaches (and calls in the middle of the night) later on. Nature’s persistent, but at least with PVC you’ve got a fighting chance.
Couldn’t agree more about clay pipes being a magnet for roots. I’ve lost count of how many times I’ve had to clear out the same lines for folks who just kept patching instead of replacing. It’s wild how fast roots can find even the tiniest crack or joint.
That said, I do wonder if anyone’s had luck with those newer trenchless liner systems? I’ve seen a few jobs where they re-lined the old clay with epoxy and it seemed to hold up, but I’m still a bit skeptical about long-term durability compared to a full PVC replacement. PVC’s smooth interior really does make a difference—less friction, fewer snags, and roots just don’t seem to get a grip.
Upfront cost is definitely a hurdle, but when you factor in the hassle and cost of repeated snaking or chemical treatments, it starts to look like a bargain. Curious if anyone’s actually regretted making the switch? Haven’t heard of it yet, but maybe there’s a story out there...

Right there with you on being skeptical. I’ve seen liners work fine for a few years, but once or twice I’ve had to go back and deal with collapsed liners or spots where roots somehow found a way in at the joints. PVC’s just more reliable in my book—less maintenance, fewer surprises down the line. Not saying the liners are useless, but if you want peace of mind for decades, full replacement seems worth the pain upfront.

I get why "PVC’s just more reliable in my book—less maintenance, fewer surprises down the line," but I’d argue there’s more to weigh than just longevity. When I looked into it for my place, I found trenchless liners had a much smaller environmental impact—less digging, less waste, and you’re not sending all that old clay or concrete to landfill. If you use a reputable installer and keep up with inspections, liners can last decades too. Not perfect, but sometimes the greener path is worth considering, especially if your yard’s full of mature trees you don’t want to disturb.
