Just climb up on the roof and start snaking from there.
You could try a quart of ammonia down the drain, then pour some hot water down it. Ammonia and the hot water will cut some clogs that chemicals will not handle.

You just have to get the water jet inserted into the right place. I E a bit lower than the drain from your tub.
