Hi Streamin, I'm a Florida Licensed Contractor and might be able to give you a little advice. The best thing you can do is to either buy hurricane shutters or make some out of plywood, have them numbered and ready for installation as the storm approaches. There are self sealing fasteners you can install so that the home built shutters will just bolt on when the time comes. The homes that are totally destroyed from hurricanes have had the door and window openings compromised from wind blown debris most of the time. Once a window or door is blown out it creates a high pressure system inside of the house, the wind on the outside is a low pressure system so uplift is created and rips the entire roof off the house. The shutters will eliminate this.
The next thing is to tie the roof frame to the wall frame because uplift is still created under the eaves. Since you are torn down to bare studs that makes it much easier. I would suggest Simpson Strong Tie products because they are the most widely used. Strap the trusses to the wall frame with either H-10 straps or H2.5 straps. The H-10 will not work if the roof is conventionally framed, but the h2.5 will work either way. The H2.5 will have to be installed on both sides of the roof framing member either way also so make sure you have the left and right handed ones. Remember to install them with 1.5" 10d galvanized nails in every hole, a palm nailer is highly advised for this, it's virtually impossible without it unless you have a positive placement gun.
Building code now requires the roof shingles have 6 nails per shingle and the first 2 runs of shingles must be glued down with tar. Once wind starts lifting the shingles that's when the roof starts peeling off, so if your roof isn't too old you should probably glue the first two runs down. If it's been on there a while you might do more damage than helping.
as far as tieing your floor down, the mobile home anchors will help on the perimeter but under the middle of the house won't do anything. I don't remeber the exact strap you need but any lumber supplier can help you figure it out. You can use a concrete fastener to affix it to the foundation piers and the palm nailer to affix it to the floor frame. Remember to only drill or shoot into the mortar joints of the blocks just incase they are not reinforced with concrete or got a bad fill.
I hope this helps you understand a little more of what happens during a storm and what needs to be done for storm situations. Wood frame houses stand up fine during a storm but must be strapped down for it.
