My brother just told me the roof guy came out and declared it a 90-100mph microburst.  There is no damage to the sub roof structures, plywood, or other...the tiles had bent nails like a very small arc.  this is like if you pull out a nail w a claw hammer.  The wind lifted up the bottom of the tiles and either pulled out nail or tile cracked and broke.  No physical objects; only very strong, strong winds...about 45-50 total tiles impacted...since they do not make those tiles anymore. will probably get a whole new roof...mother nature is bad axx !!!
