My toilet started to drain slowly. Then adjoining shower started to slowly fill up. Was my weekend home so didn’t pay much thought to it. Guest bathroom fixtures were draining fine, so i started to use it. After about 6 months finally saw neighbor and asked if she was having issues. She wasn’t. I continued to ignore and finally saw lady from HOA office. As soon as I mentioned issue she said roots. But closest ficus hedge is 30’ away. Finally I lifted the toilet and sure enough, roots had found their way and went between wax seal and sewer pipe. Needed hacksaw to cut 1” thick root. And when i was finally able to pull out the roots, it was a total ‘nest’ of roots about 4” in diameter and ~2’ long. Long story short. No roots through the pipe (sewer pipe is clear) but minuscule gap in wax allowed root to get through. There’s a product, forget what it’s called, root out or root away, but available at big box stores, it’s blue crystal stuff in a black plastic bottle about 8” tall.
