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.

Thanks, Chris...that's very impressive! My house is a combo of block and framing. But I do plan to look at and improve the truss straps and put in additional insulation at some point.
I doubt I will add the double layer like you did, though. I have a small home and with that power bills have never been too bad.
I'm curious what kind of metal panels you used. Did you get them painted white or a light color?
Thanks!
