Lightning Protection Systems

Did You Know…

  • More than 18,000 homes and businesses are damaged or destroyed each year by lightning.
  • Plug-in surge protectors don’t always protect your computers or other household electronic systems.

DeRock installs and services Harger® Lightning Protection Systems which provide complete lightning safety for your home, family, or business.

Our systems are factory tested and inspected by Underwriters Laboratories.

Generators

There’s no better way to protect your home and family from the worries of power outages than having an automatic home backup generator.

Standby generators are installed outside your house (like an AC unit) and come on automatically – whether you’re home or away. All within seconds of a power outage.

As an Authorized Dealer, we sell, install, and service Kohler® Standby Generators. We also service Generac® generators.
