I have this issue on my Z car's T-top drains. If you can catch it in time (i.e., the drains are not fully and completely choked out) you can get a high pressure air hose wiith nossle fitting on it and blow them out with the roof open. If you cannot get the air through you need to roto-ruter those suckers. There is actualy a special tool for doing this, I only know that as I had an old Maxima that was completely clogged and in LA there is a sun roof shop that did it in 10 minutes for 10 bucks for me.
Try air first. You need serious high pressure air like from a shop with a good compressor and not the air hose part for tires, one that just blows free and clear. Hopefully that works.
