I just got this birds of paradise from someone and just noticed that the root is growing out of the drainage hole. It's not blocking the entire hole but I'm wondering if I have to repot this since the leaves look a little droopy and no matter how much I've been watering it, it doesn't seem to fully perk up. The pot is a 12in size planter so it seems large enough for this plant so if yes I should repot this, could I reuse the same planter but add more soil and move the plant up a little more since the soil doesn't fill all the way up to the top? Or, should I be getting a bigger sized planter and repotting the entire thing there. For reference, the tallest leaf is only 29inches above the planter.
Below are some pictures of my plants.
