Power bill is 50% less and if a storm can take off my roof then probably the least of my problems as I doubt much will be left anyway. The extra foam and layer of plywood was not much more and the house is also really quiet inside, also have impact glass.
If you have poured concrete on top of your wall and strap the trusses you are off to a good start. I would not use asphalt shingles, they will blow off and absorb heat like crazy.

That's great stuff.
