It is possible to prevent tree roots from obstructing sewer lines. Chemicals such as copper sulfate and potassium hydroxide can be used around the sewer line to discourage root intrusion. Metal or wood barriers can also be installed around the sewer lines to keep them free of root damage. When landscaping, it's best to limit the amount of plants or trees placed in close proximity to sewer lines.
I want to thank Luis and Charlie's Rooter Service for Outstanding customer service. Luis came out for a clogged shower and later to find out that the cause was my main sewer line. He was honest on the cost and what needed to be done, Luis gave me options to make my decision easy. He was polite and professional, if you need quality work I would recommend Luis and Charlie's! Thank you Luis
