>From what I have read, it started in 1975 following the "America Burning" report. It seems the recurring theme is to prevent flashover, and be affordable. A GUESS would be attics were never included.

If you choose to protect it, then I think you would be subject to 13. With the new requirements for slopes of 4/12 and greater.... As usual, the AHJ can sign off on something. My 1.28 cents.

I am curious as to the requirements for protecting attic spaces (if there are any). I have an existing house that has a 13D system that was installed in 1986. For some reason, the entire attic space is protected. I have the original drawings and calc's and the attic portion was designed with a 2-head calc like the rest of the building. The problem we are having now is that the entire roof (including the trusses) is being replaced. The original roof had a 3 in 12 pitch. The new roof has an 8 in 12 pitch. What do I now do with the existing uprights in the attic. Should they just be removed? Or should they be extended up to the new roof? If I extend them up to the new roof, what design do I use?
