My various houses have been hit four or five times. None of the times while I was inside. It blew concrete off the roof and scorched paint and exposed rebar. The most damaging hit scabbed a two by four feet area and melted one inch off a rebar cross brace. About two and a half inches deep.
Being the power was off at the time, it lessened damage to mere structural except for an utterly fried and melted structure to earth 6 gauge ground rod cable.
I heard but did not see the strike as I was beneath a palm frond roof of my kid's beach restaurant. The goat lady living at the bottom of the arroyo told me she saw the flash then she had to go chase down her goats.
Repair amounted to a sack of cement, sand, ground onyx and sealer. Quicksilver's roof is at the floor level of the concrete patio.
Average dry summer thunderstorm - can count on 20-30 recycling of line reclosers on the 86KV line. Unlike the USA Mexico has sub distribution networks where a 20 Kw transformer may deliver power to ten or 15 homes. Luckily they are three phases plus neutral WYE transformers.
Absolutely the only lightning direct strike protection a person can do to a service drop is to make some alternate pathways and pray a feeder stroke elects to take it instead of continuing on into a breaker box.
Fully unplugging everything you value from receptacles beats switching off the master at the main breaker as far as protection goes.
Neutral must be isolated every bit as much as the hot phase wiring.
Ugh I hate lightning.
