any tips on colouring 3 month roots

For the future, it is much easier to do roots that are less than a centimeter long, as you are less likely to get a noticeable line of demarcation (because even if you get one, it hides in the shadow of your scalp).  This does mean doing roots about every 3 weeks, which is a commitment.  For now, you may just have to try to do the dark parts only, then after you have them close to the same color, dye all of your hair again (covering the length too) so that the line of demarcation gets blended (the second dye job may only need to be short in time, like 10 minutes...I don't know what color you are going and from what color). In the future, if you do your roots frequently, you should not need to refresh your length (which is damaging) unless you have a color that fades.

Do test strand, for 3 reasons.  To make sure you aren't going to overdamage your length, to be sure that dyeing it all again will not make it come out any funny colors, and to make sure that you won't do it if it isn't going to work to cover the potential line of demarcation, giving you damage for nothing.  (The length may absorb more color than the roots if you're going darker, or if you're going lighter, it may come out different in the other direction, so definitely test strand the whole process so you don't mess up your hair with either step.  Test strands will also help you get the timing right).
