Sewer line replacement

I had tree roots growing in my sewer line. Had to roto rooter it and it was fine for a year. We had the trees removed and it clogfed again. Roto rooter again and in a month it was clogged again. Used a balloon to push the clog through that time and haven't had an issue in over two months. The plumber told us without sending a canera in that we need our line replaced. I have the money saved up to do it but am wondering if i need to replace it since all the trees are killed and we have had zero issues since. With winter coming up i need to make a decision on if i am replacing it or not fairly soon.Any suggestions ? I am leaning towards having a 3rd partt put a camera in there but i dont know what they will be able to tell me or see

 

I would definitely have it checked with a camera. I would consider that money well spent.
The roots may no longer be a problem but the pipe may be partially collapsed or cracked now.

 

I'll second Pete's suggestion of a camera. The few hundred dollars will be well spent to determine the actual condition of the pipe.

I'm actually a little surprised that the drain cleaner didn't include the camera as part of the clearing. The big companies around here (Roto Rooter, Zoom Drain, etc) run a camera to determine the issue, prove it's clean after the snake/jet, as well as indicate if there are other issues that may cause clogs in the future. It's sort of 'proof' for them that they did a good job cleaning the pipes.

Also, for roots, I'm not quite sure how well a balloon works. The roots in the pipe need to be either cut with a snake cutter head, or with a jetter.

Long story short - get the camera scope and see what's there.
