The last storm of any significance we had in my area was back when I only had half the roof on my shop building and no wind bracing to speak of we had some recorded 10 to 15 minute long sustained winds in the 70 to 80 MPH range with gusts well over the 100 MPH mark. The building didn't receive any damage, and the 25 year old metal roof on our house only had a few screws loosen up which I replaced with longer ones and added more in may areas where I felt there were not enough screws.
A brand new pre engineered building was being erected about 5 miles away that didn't fair so well. Columns bolted to the slab all of the trusses were installed and the purlin for the roof and sides. they had that thing cable braced 9 ways from Sunday even had temporary bracing in all of the door openings. And only about 1/4 of the roofing on as well as the siding on one end which had 2 12 by 12 doors.
My building is 18 ft to the eves and 26 feet at the peak 60 ft by 68 ft the other building was and I mean was 40 by 60 with 13 ft to the eves and 16 feet to the peak after the storm it was largely scrap metal it had to be torn completely down some of it was salvageable so they rebuild it as a 40x40
The wind can do lots of damage in a very short time to things you would never expect to be damaged by
