As a plumber in Las Vegas, I commonly see roots growing through pipes. It is honestly hard to provide a quote without performing a sewer inspection myself and seeing exactly where the roots are penetrating the pipe. There are other factors to consider in addition to the repair, such as whether saw-cutting through concrete is necessary. An experienced plumber will be able to walk you through the repairs. You may also want to contact your home owner’s insurance to see if they are able to pay for any of the work.
