We put allowances in the 2010 edition. But you gotta meet the four criteria found after the following paragraph. Let us know if your mansard meets the requirements. 8.15.1.2.18 Sprinklers shall be permitted to be omitted from within combustible soffits, eaves, overhangs, and decorative frame elements that are constructed in accordance with 8.15.1.2.18.1 through 8.15.1.2.18.4.
It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the AFSA, NFSA, NFPA, nor any of their technical committees.
