Why Aurora sewer lines fail the way they do
North and central Aurora were built when clay tile was the standard lateral material, and the cottonwoods and elms planted alongside those streets are now sixty and seventy years old. Clay joints weep a little moisture, roots find the moisture, and the joint becomes a strainer that catches everything the household flushes.
East of Chambers the story flips. Newer PVC does not leak at the joints, so the failures we find there are grease, wipes and settling rather than root intrusion.
The two-block rule for root intrusion
If a mature tree stands within about two blocks of your cleanout and the house predates 1975, assume roots are in the line and put a camera down before you spend money guessing.
What a cable misses that a jetter does not
A cable punches a hole through the blockage. Hydro jetting scours the pipe wall back to its original diameter, which is the difference between a clear drain for three months and a clear drain for three years.
