Ooo,ooo...this is a good one. Let me in on it!
There are varying opinions here. Mine is this.
Any root intrusion requires repair or replacement. Cabling removes a portion, especially along the flow line, but not completely. Once the flow line is open a jetter, with the proper head, can be fed through and most of the roots cut and flushed out.
But cabling and jetting is not a solution to the problem and this should be explained before any service is provided. It's the ol' "Throwing good money after bad" scenario.
I have cabled, jetted and camera inspected many sewers. Depending on the tree and conditions, roots can grow back within a few weeks, even with a chemical treatment after the mechanical removal of the roots.
After a tree is removed and ground down to grade, the roots can continue to grow for years afterward.
I have inspected a few building drains where a hdpe was pulled (pipe-burst) through and the sewer still had occasional back ups. The bellies from the original t.c pipe were repeated through the new pipe and waste would collect in the low spots. Roots can affect the soil support around old pipes and cause shifts as they continue to grow.
I could never give a warranty for any period of time for a jetter job on roots. Unless a repair is made, no warranty. It's like betting against Mother Nature and that's never a good idea. Some companies offer the warranty as the set up to justify the dig job. That's fine. Just as long as everything is up front before the first service call starts.
Okay...I'm done for now. Back to work.
