Lightning strikes the earth 6000 times per day.

Each year, the United States has 5 billion dollars of property losses from Lightning damage.

Lightning causes damage in three ways:
1) Destructive explosive effects
2) Electrical shock which damages electrical equipment and can kill people and animals
3) Fire, causing intense heat (Lightning is actually 5 times hotter than the sun)

Woods Lightning Protection Systems are composed of a "Franklin Style" Lightning rod system, combined with modern state of the art surge protection and grounding equipment to protect buildings from structural damage along with protection from damaging power surges.

Properly installed, according to the requirements of Underwriters Laboratories Standard Code UL 96A and National Fire Protection Association Code NFPA 780, a Woods Lightning Protection System is designed to form a passive electrical ground system which moves the earth ground electrically above the house.

This makes your home appear, to a storm cloud, to be sitting below ground.

A Woods Lightning Protection System includes 10 or 12 inch copper Lightning rods, or air terminals, which are mounted on the roof of the house at the end of all ridges and at a maximum spacing of 20 feet apart.

Air terminals are also mounted on chimneys, turrets, cupolas and dormers as needed by code. All of the Lightning rods are connected together in series with a heavy copper cable which is installed to give each Lightning rod a 2-way downward path to ground. Lightning conductor cables are stretched tight by Woods installers and fastened at three foot intervals to the structure in the least visible locations, such as behind roof caps and downspouts. Downlead cables are terminated to ground electrodes, which are 9 foot ground rods, that are driven to a depth of ten feet at the corners of the building. Copper ground plates are used in very rocky locations.

When Lightning strikes a properly installed Woods system, the earth charge building up in the ground around the structure is picked up by the ground electrodes. It then flows up the copper Lightning conductor cables to the air terminals where a finger of Lightning bleeds off of the point to intercept the downward Lightning stroke from the cloud. When this happens, millions of volts of electricity transfer from the cloud to the ground until the difference between the negative and positive charges are neutralized.

Lightning rods provide a protective area below them at a 2 to 1 angle from the air terminal on the structure up to 25 feet in height and at a 1 to 1 angle on buildings up to 50 feet in height. The area below this angle is called the "Cone of Protection."
