Cloud Search [Q] Will rooting void warranty if i do not install cwm in it

I mean i do not intend to flash lg g2 (no installation of recoveries like cwm or twrp)

just root it and enjoy adblock titanium backup and all (without uninstalling crapware)

Will it void my warranty

If yes would i be able to restore it to normal perfectly

would i have to unroot before ota updates

Note: I have already rooted and flashed my canvas hd many times
and would love to use root dim, screencast adaway and droidwall on this phone.
