In modern constructed houses you have so called "hurricane straps" securing the roof trusses to the walls. .
An interesting note, I talked to an insurance adjuster a while back and he told me that after the tornado that hit a neighboring city a few years ago, they found that the newer houses with hurricane clips attaching the roof trusses to the walls suffered more damage because when the roof lifted it tried to take the walls with it and destroyed everything. But the older houses built with only 3) #8 nails toenailed holding the trusses fared better because the roof just pulled off and left the walls intact.
"Just sayin..."
Yeh, I hear that, not witnessed it myself though, just know that I have a hurry cain bolt into the slab every 2-3' or so around the perimeter of the room addition, and I just wrapped the studs with Tyvek waterproofing and screwed the hardiboard over top of it, stuffed in insulation and done, it's on the east face of the house, so the coolest room in the joint, easy....house faces direct west....largest single bang for the buck was replacing my 5'h x 6'w front LR window with plastic thermal, lo E this dropped my LR temps by nearly 20f when the western sun streamed in....but since then wife has added a deck, and a roof, and a ton of plants/flowers...but I did all the windows in the house, gone are the 43 y/o single pane aluminum junk...I paint the roof white, number ONE, I had the lightest gray shingles available on there, they reached 165f in the summer sun by 11AM in the MORNING....
took various probes to the attic, the attic temps were clocking an easy 145f by PM......decreasing down to about 115 just above the insulation, I have roof vents long the peaks of the roof in back of the house, and of course ~2' overhang and vents there too....WELL, I found that painting the roof white, reduced my attic temps by .......get THIS.....40f.......105f on the plywood.....cut about 80-100 bux/month off my summer AC bill.....saved my ass this summer alone.....
IMO the only roof worth having in
FLORIDA is white metal.....:devil:
