Only way for device's bootloader to get locked again is when you do that manually. That will never get re-locked otherwise. (Perhaps only when reflashing original stock bootloader, but don't know that).
With SuperSu Pro licence with option OTA Survival Mode after OTA you don't need to reflash to get root back in most cases/devices. But always first check if SuperSu is updated yet after new OTA before applying the update. Developper of SuperSu is always very fast with needed updates.
I read OTA Survival Mode had some problems maintainng root after OTA 4.2.2=> 4.3. I only experienced OTA's 4.3=>4.4=>4.4.2. All times still root after OTA-updates.

Just in case I have this text file in my Nexus 7 (2013)-folder on my PC.....
Worst case scenario, have to (re-)root manually with keeping original bootloader and recovery:
1. Copy the zipfile(s) you want to flash with TWRP to internal SD of Nexus. (For example latest SuperSU download:http://download.chainfire.eu/396/Sup...erSU-v1.94.zip
2. On PC download and extract to folder latest Android SDK. Go to folder 'Platform' or Platform Tools. (Folder including adb, fastboot, etc.). ( Android SDK download: https://developer.android.com/sdk/index.html
3. Download and extract latest TWRP(.img) for Nexus 7 Flo and copy to folder Platform/Platform Tools (with adb, fastboot, etc. in it) You might want to give 'recovery-twrp.img' a shorter name. (TWRP download: http://techerrata.com/browse/twrp2/flo
4. In the folder with the platform tools while pressing <SHIFT> on keyboard, click right mousebutton somewhere in folder and click with left mousebutton on 'Open Command Window Here'.
5. On Nexus switch on 'USB Debugging' in system settings-> developper options. Shut down Nexus.
6. Connect Nexus with Usb-cable to PC. Start the device untill untill Nexus 7 folder opens on PC.
7. In earlier started Command Window type 'adb devices'and push <ENTER> on keyboard. If all is well you will now see that Nexus is connected in Command Window. (If says device offline that means missing/incorrect hardwaredrivers or USB-cable broken/not connected)
8. On the Nexus appears the messagge 'Allow Usb Debugging'. Tap 'oké/yes' on Nexus.
9. In Command Window type 'adb reboot bootloader' and push <ENTER>
10. To load TWRP without flashing for temperary use now type in Command Window 'fastboot boot twrp.img' and push <ENTER>
Now TWRP loads and can be used without losing stock recovery
Flashing with TWRP:
1. The zip(s) you want to flash must be copied to internal SD in advance. (for instance latest SuperSu.zip)
2. In TWRP tap on 'install'
3. Browse to the zip you want to flash and select by tapping on it
4. Now 'Swipe to confirm flash'
5. After reboot
