To be honest, we would need pics to really be able to have a guess at what is going on. It doesn't sound quite sabino to me.
Sabino can and often does have roaning associated with it. A horse can even have just the roaning expression of Sabino without the white markings. A sabino roan will have roaning on the face and legs, unlike "true roan."
A horse with sabino markings often has roaning around or near those white markings, but can also have random roaning on other parts of the body.
That said, the op's roaning sounds more like Rabicano. Can you post some pictures? Any roaning around the tail or on the ribs?
