In a prior post I discussed strategies for avoiding injuries to human beings from lightning. This post is going to focus on strategies for protecting the structures themselves from being struck by lightning and from lightning damage. Ardent followers of this blog might recall that this interest of mine has been piqued by the lightning strike of one of our large metal roofed outbuildings, while a family member was inside. Our family member is still recovering from the damage received in last autumn's injury. I am still doing research on exactly how we might have lightning rods properly installed and grounded on the multiple types of farm buildings and the home we have, each of which have differing types of roof lines.
One cannot place metal lightning rods on the top of the building alone. It is necessary to place a grounding wire from them and properly anchor it to ground. Improperly installed lightning rods may be more dangerous than not having lightning rods at all.
The following information comes from:

Their work product is provided between the two rows of undulating lines. Please contact them should you need to buy articles in order to protect your own buildings from lightning.
|(Comment by Jane)This is a simple drawing which illustrates that lightning rods need to be attached to grounding wires in order that the lightning may travel and dissipate in the ground, rather than through your building.|
|(Comment by Jane)This picture illustrates the complexity of lightning protection in a larger or more complex structure. Should you need to see this diagram larger than this, it is available at http://www.lightningrodparts.com/installation.html The correct materials and the correct mode of installation are essential. If you are unable to do this correctly, you should contact an electrical contractor with experience in lightning rod installation and lightning abatement. Be sure to check their references.|
Electrical contractors who specialize in lightning rod installation may be expensive, but damage to your home may be much more costly. Before adding lightning rods to your home, you should contact your homeowner's insurance carrier. A few of them will not insure homes with lightning rods on the off chance that installation has been done incorrectly.
In many areas, lightning is a rare phenomenon which tends to strike either in the hills or in the ocean. For some of us though, especially those of us on properties with metallic ore in rocks or with buildings on a high perch, lightning strikes are a frequent and dangerous possibility. We had a lightning storm yesterday, in February !
