Fire hazards of radiant OSB

Today's 4 yr old house has it. Should I write it up?

The roof panels have a thin layer of aluminum attached to one side to give it radiant properties and reduce energy costs but it's electrically conductive and has been found by some to be a fire hazard if lightning should strike the house. You should replace it with regular APA-rated OSB roof sheathing.

Won't be cheap, that's why I pause.

It reminds me of CSST. It's a hazard because it's conductive and can't safety handle the current of a lightning strike.

Marc,

Sure you can write it up (like many things we note in our reports), but it is doubtful that anyone would act upon such.

To say the least the study is an interesting read and it does give me pause as well.

Thanks for providing.

The document is 4 years old as far as I can tell. I would think there would be more evidence and uproar if metal radiant barriers were a big risk. I'm not saying it is not a problem, I just don't know that much about it.

I'm in a high lightening area (as defined by the CSST criteria) and there have been hundreds of thousands of new homes built locally over the past 10 years but I have never heard of a problem. Anyone else have more on this subject?
