I like the idea of using 'Hurricane Clips' in the post above. They may hold your roof for a F1, MAY. Bright Sinkers to nail the roof trusses should be banned. I use construction screws for most. Takes a lot longer
I also use 1 1/2 inch #8 construction screws to hold my roof plywood down and use the roofing nails that have the square and are ring shank.
We do get F1 and F2 tornadoes up here in western Washington State. But more likely just a 70 to 100+ MPH blow 5 or 6 times a year. Derencho Storms
