The best roof for a hot & humid cimate in alabama

[raftingangle]

Hi everyone, I am so glad to know this wonderful forum.

I am planning to build a small house in the countryside of Alabama, where the climate is hot and humid all year round, with an average temperature of 32-35°C in the summer and 5-10°C in the winter. I want to build a suitable roof that is both heat-resistant and warm in the cold season, while saving on construction and maintenance costs.

Do you have any experience with which type of roof is best suited to this climate? Should I choose a traditional tile roof, a corrugated iron roof, or a flat roof? And if I choose a corrugated iron roof, what type of insulation should I use to reduce the heat in the summer?

Thank you very much!
