Houses with strong roofs

[alfredahud]

Hello guys,
I live in Miami and and get a lot of snow in the winter. I'm looking at some of the new 32 wide homes. Do any manufactures build a roof with a 4/12 pitch and metal roofing. Plus 80 or 100 pound snow loads. It seems that most of the manufactures want to build the cookie cutter houses that don't have strong roofs. Any suggestions?
