To vent off odors emanating from the septic/sewer system and to allow the toilet to flush correctly and the other drains to empty correctly.
A auto vent
Yes BUT not an outside wall
Vent through roof
I don't quite get what you mean. -A vent pipe in a plumbing system is usually 1 1/2 inch ABS pipe and may extend through the roof, or may end in a AAV under a countertop.
Plumbing vent pipe is installed through a cathedral ceiling and metal roof surface there is no easy access into the roof cavity. In an attic after cut off the elbow whose female end contained the remains of the ABS pipe, glued on a short extension and new elbow in the attic, and glued a new plumbing vent rooftop riser into the new elbow.

No plumbing code allows a loop in a vent line. They must be pitched just like a drain line as there are many conditions where water can be in a vent line, such as rain through a roof vent and condensation. If the "u" were to fill with water it would no longer function as a vent.
You install the plumbing along with the bathroom.
A auto vent
vent in bathroom manditory
Yes BUT not an outside wall
yes,
Vent through roof
You should not have to clean a vent on the roof. unless you are trying to clean the waste line to the fixture below. Then you would send plumbing rods through the vent on the roof.
A vent for the drain system may be blocked. A home or building plumbing system must be "free flowing" with a vent to the outside atmosphere - usually through the roof. When water is forced down the drain and the vent for that drain is blocked, air will be pulled from inside the building through another plumbing fixture causing the gurgling sound. The main drain line may also be partially blocked whereas when water is forced down the drain the air in the drain line may be forced back into the building through another plumbing fixture causing the gurgling sound.
Yes it does, otherwise it will vent in your bathroom and make everything stink. and it is not a very attractive sight to see.
In plumbing the roof vent should be a min of 4" to prevent hoarfrost
There is NO SMELL in my bathroom as all my fixture traps are in place and all fixtures are individually vented and I installed a 4" vent terminal to prevent hoarfrost and the FAI is high enough above grade to allow for free circulation of air
