Default OTA update after rooting

So.. I was on 14.2.A.1.136 (4.3) stock firmware.. I wanted to root and I had to downgrade to 4.2.2 then root then flashing 14.2.A.0.290 (4.3) firmware.. Thanks to @shem2409 and @[NUT] for this method.
Anyway.. After rooting and flashing and all of that.. I received an OTA update for the stock 14.2.A.1.136 firmware.. And I was really surprised because what I know is that you lose the OTA updates and pc companion updates capabilities after you root your phone.
So my Question is.. If I updated the firmware OTA will I lose thr root? I can't afford to root it again for at least 3 weeks because my laptop is on the maintenance right now ..and I need the root privileges.
