What is a disadvantage of installing lightning protection systems?

The choice indicating that lightning protection systems can be expensive and require maintenance accurately highlights a key disadvantage associated with these systems. Installing a comprehensive lightning protection system can involve significant upfront costs due to materials, installation, and the expertise required to ensure proper setup. Furthermore, regular maintenance is essential to ensure the system functions effectively over time, as environmental factors can lead to wear and tear. This ongoing requirement for maintenance adds to the total cost of ownership and can be a barrier for some property owners.

In contrast, the visibility of lightning protection system components such as rods may vary based on installation choices, and while some may prefer the aesthetic look, others may find the components acceptable. Additionally, these systems are designed to effectively redirect lightning strikes away from structures, so concerns about ineffectiveness can largely depend on proper installation and adherence to standards. While animal damage can be an issue for exposed components, it is not a primary disadvantage of the systems themselves, as they are mainly focused on providing protection from lightning.
