I lived in Tennessee for 34 years and there are many very old houses with the old style flat metal roofs that have been on the house since it was built 50 or 60 years ago. Tennessee has it's share of tornados and straight line winds and those old roofs handled it quite well where as asphalt shingles were another story.
We had a metal covered roof pavilion in the back yard, 20 feet by about 12 feet. We had a severe straight line storm come through one night. Something like 75 houses, including ours, had to have new roofs, all were asphalt shingle. Our pavilion was blown down as were 8 large trees in the back yard. Not one sheet of metal came lose.
As I stated, the new metal roofs aren't the flat or corrugated barn roof metal, they are stamped with a regular shingle pattern and look just as good as an asphalt shingle roof. Apparently some like to replace their roofs every 10 or 15 years.

Metal roofing paint fades quickly in the Florida sun. Furthermore, when pieces peel off in a hurricane they tend to become lightweight projectiles while their counterpart asphalt shingles usually cling to the ground. Homes are too close for the catastrophe. Also, metal roofing is secured by less fasteners per square foot. An asphalt shingle is usually nailed down with two nails and is sized ar 12” by 36” or for every 3 square feet. Metal roofing required much less fasteners per square foot.
When a roof is damaged during a storm, who decides what is unsightly? What if a neighboring home has an ugly damaged metal roof , but it is serviceable? It’s a great thought, but there are too many reasons to not install them in Florida.
