I have a similar background.
Key factors influencing my decision to install lightning mitigation as a preventative likelihood/risk reduction include:
* Seven homes struck within a 3 mi radius of our home in the 4 years here.
* Fires tend to start in the attic with the homeowner unaware until a neighbor notified them.
* CSST Gas lines in attic acting as lightning rods:
- the CSST manufacturer recommends LPS in lightening prone areas if installed.
- Several strikes appear to have been at the garage corner where the iron gas line enters the attic.
- Nearby lighting strikes can punch pinholes in the CSST tubing resulting in delayed/undetected gas leaks, until something ignites them.
* The Villages installs LPS on critical buildings and infrastructure.
* LPS is required by code for schools, retirement homes and hospitals.
* There is discussion to add LPS to the building code -installation cost would be much lower during construction.
* It takes 2-3 years to rebuild a home here destroyed by lightening.
* For us, the cost was less than our $2K deductable.
