Five signs that justify checking a sewer for roots

A practical guide for Detroit homeowners.

Roots are one possible cause of a recurring sewer blockage. None of these signs proves root intrusion by itself; useful inspection findings should guide the next step.

1. The same blockage keeps returning

A line that clears and then slows again at a similar interval may still have a restriction or damaged joint. Keep the location and findings from the earlier visit. Repeating a cleaning without comparing the evidence can leave the underlying fault unexplained.

2. Several fixtures react together

A toilet that bubbles when the washer drains, or water rising at a low floor drain, can indicate a shared restriction. Roots are one possibility, alongside deposits, foreign objects and damaged pipe. The affected fixture pattern helps choose the inspection route.

3. A previous visit recovered root material

Recovered roots support a root-entry concern, but they do not show the full condition or length of damage. Ask where the roots were encountered and whether a camera inspected the joint afterward.

4. The camera shows growth at a joint

Visible roots at a joint are stronger evidence than lawn appearance. The recording should show the accessible section, condition and any limit to visibility. A location survey may be useful if a targeted repair is considered.

5. A known damaged joint has not been repaired

Clearing roots can restore flow while leaving an entry point. Ask whether another cleaning is reasonable or whether the recorded defect supports a repair. The answer depends on the remaining pipe, access and condition.

Questions before you book

Does a green lawn stripe prove a sewer leak?

No. Lawn color has several possible causes. A sewer concern needs appropriate inspection and testing.

Do roots always mean full replacement?

No. The extent of damage and pipe condition determine whether cleaning, a targeted repair or another method is appropriate.
