WHY is it placed on top of the building the ligthing rod?
Because lightning is always attracted to the highest points. Lightning rods are attached to long, insulated cables which lead down to the ground - and are anchored deep in the earth. Placing a lightning conductor at the very top of a building, almost guarantees that any strike will be conducted safely down to earth.
What happens when lightning strikes a house?
There are a number of things that can happen depending on the sercumstances, lightning takes the shortest route to the ground, so if there is a lightning rod on the roof it would travel a safe path to the ground.

What is the function rods?
A lightning rod (US, AUS) or lightning conductor(UK) is a metal rod or metallic object mounted on top of a building, electrically bonded using a wire or electrical conductor to interface with ground or "earth" through an electrode, engineered to protect the building in the event oflightning strike. If lightning hits the building it will preferentially strike the rod and be conducted to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution.A lightning rod is a single component in a lightning protection system. Lightning rods are also called finials, air terminals or strike termination devices. The lighting rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute of all lightning rods is they are conductive.
How can you create a lightning rod?
In a thunderstorm any piece of metal that is above all other objects in the sky will act as a lightning rod. ************************************* A metal lightening rod is fixed above the highest point of a building, (as in the answer above) and a metal strip or heavy cable is connected between the rod and into the earth, so directing any lightening strike to earth and safely dispersed.
