I had to deal with roots in my line (soil pipe) every six months like clockwork. After spending several hundred dollars getting this done professionally on a regular basis, I had a local "one man shop" plumber come out to remove the roots. Instead of the usual large heavy sewer cleaning machine (like the rental places have) he showed up with an old car tire and a BIG electric hand drill. Inside the tire was a coiled up length of the sectional cable normally used on the large machines. He cut out a bucket full of roots from the line and all was good again.
I told him I wish I had his set-up, and I would just do the job myself! This guy was
so nice, he actually told me of a local drain cleaning supply company where I could buy the sectional cable and a root cutting blade for it. He said they even have the adapter's to hook it up to your drill.
I went there the next day and bought 50 feet of the cable, the adapter, and a couple different root cutter and auger heads. I left there and went to Sears and bought the biggest industrial drill they had. For the cost of 3 service calls from the pros, I had everything I needed to do the job myself. And I did it - every six months as usual for several years.
I had a tree in my back yard near the house that was getting too big and troublesome, as it was overgrowing my house as well as the neighbors house. I decide it was time for the tree to go, so I had it cut down. I killed the stump to prevent it from starting to grow back and causing more problems. As time passed it hit me one day..... Hey! I haven't had to clean out the sewer line since!
