I grew up or lived on islands in the pacific particularly one. Considering that islanders lived in homes that were built of natural resources, it was bad but not that bad, just throw back up coconut tree leaves for roofs and sides. Also many buildings were built of concrete. The Japanese long ago built concrete buildings with concrete roofs with coverings for the windows that could be lowered when needed. Our home there was a concrete building with what looked like a standard angled sheetmetal roof. We had steel cables that went over the roof. There were wood runners running across the roof under the cables. The cables were slacked when there were no storms and then tightened when a typhoon was headed our way. Never had any issues when hit. Islanders knew where to hide through their history so that's how they protected themselves. As they modernized and built western style buildings, there of course was more damage from storms. So yea, not sure about straps but I can tell you cables work. And yes, those cables were anchored to steel eye hooks that were set deeply in concrete. Nothing was moving those ! And yes, many places now require securing roofs to the buildings.
