In the past 34 years, I’ve lived in three houses with steel roofs, and I love them. My home in The Villages has a new architectural shingle roof, so I won’t have a metal roof in Florida, I’m afraid. Bu I recommend them Definitely! However, use white! Studies show that white roofs reflect the most sunlight, and when sunlight hits roofs, it turns into heat, so more reflected light means a cooler roof. A white steel roof is still very hot indeed, but way cooler than, say, dark grey. One possibility sometimes used is to remove the old shingles, attach an inch of foil-faced insulation to the plywood, screw 1x4 wood horizontally through the insulation and into the roof trusses, then screw the white metal roofing on. Makes for a strong roof that can handle winds and cool your attic a lot, which cuts heating bills a lot. I wouldn’t use the metal fake shingles. If you want a shingle look, use shingles.
