How does a tiled roof perform in high winds?

The weight of the individual tiles, their interlocking and overlap, plus the single standard fastener will keep the tiles in place in areas with wind speeds of up to 80 miles per hour (128 km/hr). In areas of higher winds, there are alternative and especially strong fastening methods that can withstand up to 140 miles per hour (225 km/hr) wind speeds. The Gambale roof system was tested in such a special configuration at speeds up to 170 miles per hour (273 km/hr) and it passed the Miami-Dade test in Florida which is considered to be the most rigorous tests for roofing against hurricanes in the world.  more
