Have you ever walked into a metal building where the metal touchs the ground and wondered why your cell looses signal? The exact same reason that lightening rods work but little more simple due to the strength of the lightening. Also when lightening is getting ready to strike the air will become charged--you can feel it. I have absolutely no fear of my shed will be hit by lightening. Pole building with a full metal skin; metal roof touches the metal facia which in turn touchs the soffet which is in contact with the sides and that touches the ground. Forms an excellent Faraday Shield killing a cell phone signal in the building and out about 20 feet. It also drains the charge out of the air during thunderstorms--you ask how I know that--I have experienced it. Drove in with the hiar standing up on the back of neck walked up close to the building and it just went away. That draining of the charge prevents the strike; however should a strike occur it will ride the building skin into the ground.
