Lightning Protection

A tree that has taken hundreds of years to grow can be turned into splinters in an instant by a bolt of lightning. To avoid this devastation, we designed lightning protection systems for large trees. Trees that have a high potential for a lightning strike are usually (but not always) the tallest objects around or found standing alone on open hillsides.

Some trees can survive a lightning strike. However, a tree’s ability to recover depends on the tree’s species, health, and moisture levels as well as the lightning’s power. In a severe situation, a tree could pose danger to your property and may need to be removed entirely.

Installing a lightning protection system is a proactive way to keep your tree and property protected.

A tree lightning protection system offers a convenient, low resistance path for electrical charges. When a tree is equipped with a protection system, the positive ground charges travel up through the system to meet negative cloud charges traveling down toward earth. Both charges are instantly canceled out, sparing the tree.

We design our lightning protection systems with high-quality copper cable and hardware made to last the lifetime of your tree. The design of a particular system is determined by the tree’s unique characteristics, starting with a main or primary conductor cable that is run from the top of the tree down into the ground. Smaller cable is used to extend the system out to the side of the tree.

Lighting protection systems should be handled by professionals. A certified arborist knows how to install a system that does not attract lightning functions properly. At Cortese Tree Specialists, we can recommend the installation of lightning protection systems where appropriate.
