NO! It is even highly discourage to attempt to root your phone as it risks "permanent" damage to the device especially when done with someone with no prior knowledge nor experience in rooting. (Jailbreaking is the equivalent term of rooting in Apple devices.)
What rooting does is give you root access (something like admin/system privileges) to your device. This means that after rooting you can modify the software code of the device and/or install other software that the manufacturer wouldn't normally allow you to, which is very risky considering there are many malicious app out there and might also overwrite system data files need by the device.
People usually root their phones when they try to install a cheat/hack that will give them free access to something (like a free internet) or a game hack as they can now freely modify the data installed and hidden on the device.
Because of this very same reasons, one who have no knowledge on what data file they are modifying, deleting, installing and/or moving risks the phone's security and processes running in the background. A 12Kb Data File named CHasd77123hnASqwe (totally random string) could be seen as a spam data file and be deleted by the user, but that data file could be used by the device when rebooting. The moment that file is deleted or overwritten then you can no longer reboot your phone.
This is one of the many risks of rooting your device and is the main reason why manufacturers don't give users 'root access' to the device, to avoid any tampering/modifying of code and data used by the device.
