[Q] Lost root access after 4.2.2 update

My N4 was on 4.2.1 and I managed to root it using the video guide here (http://www.youtube.com/watch?v=sV355YEDzc8&list=FLym1yJ2TTTjBZbty0DrqsKQ&index=3). It worked fine and I was using Titanium Backup with root access.
Then my phone notified me of the 4.2.2 update so I installed it OTA. I thought I still had root because SuperSU was still there. However, when I load Titanium Backup it says:
"Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted, and try again. This attempt was made using the /system/xbin/su" command"
I then installed a Root Checker (https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&feature=nav_result) which indicates "This device does not have proper root access".
My questions are
How do I regain root access in a way that doesn't cause a full wipe of my data?
Will I have to do this every time I apply an official Nexus update?
What is the best way to apply an official Nexus update maintaining root without having data wiped?
TIA

I personally use the toolkit and option four. Every time I install an update, I lose root, but the toolkit easily restores it each time.

I too lost my root when i got 4.2.2 OTA. I used WugFresh's toolkit and rerooted with it. I also flashed the CWM custom recovery, which I've read prompts you to keep your root after rebooting with an OTA update.

If you have cwm and you install any update that breaks root it will ask of you want to keep root when you choose to reboot the nexus 4.

Q) Root doesn't work!
A) From a clean build you need to enable root access for Superuser itself. This is different from 4.2.2 in which Superuser by default had root access on a new install. To do this, go to Settings -> Developer options -> Root access. If an app attempts to request root access before Superuser itself has access, it may cause problems with that app in the future where root requests are silently denied.

[Q] From Superuser to SuperSU, is that possible?

Hi guys,
I have rooted my phone with ioroot method. It came with SuperUser Apk, now I want to change it with SuperSU.
Can I just install SuperSU then uninstall SuperUser without losing root access?

That's what I did. SuperSU works fine for me. You can always install SuperSU, make sure it works (it should), then uninstall Superuser.

Uninstalling SuperUser does not remove root access and you can do that. However if you don't turnaround and install a superuser type of app (ex: SuperSU) shortly and then try to access an app that requires root (ex: Titanium Backup), then you will not be able to use the app. It is best practice to install a superuser app as soon as you install another one to ensure there are no issues.

Root works but no root application

Hello,
After upgrade my nexus 7 from 4.4.4 to 5.1.1 with nexus toolkit all application needs root works perfect, but no root app (e.g. SuperSU or Superuser) appears in menu. I installed SuperSu from TWRP recovery but Application list in SuperSu is empty and all apps needs root works without showing message to allow or deny root access.
How can fix it?

After re-flashing system.img an new installation of SuperSU from TWRP, the problem solved!

Chainfire root j500FN root problems suddenly not rooted anymore

I got it rooted but just the first apps that required root got access granted now when i use root checker or want to use a root firewall it says it's not rooted. Root checker says its not rooted. But i granted 4 apps and now suddenly its not rooted anymore. How can that happen i even got superSU pro. Tried to root again with Odin still same problem. Only got the 4 first apps i installed that required root then its not rooted anymore.
