Getting a tear down, new re-roof soon…(storm damage) *no insulation in 2:12, 30sq roof, all cathedral ceilings….No attic space either. **probably have 50-65% tree coverage… *looking for reduced AC/heat bills…
Kevin,
You have asked the right question but at the same time you have answered some of the basic questions in determining a solution.
Choosing a roof
First, your 2:12 pitch roof. Because of your geographical location and known high winds, I would recommend looking into a standing seam metal roof.
This approach will allow you to handle some of the worst weather conditions and comply with the Miami-Dade regulations common in most counties in Florida.
One roofing type which meets Miami-Dade regulations is the UC-3 standing seam metal roof profile manufactured by Firestone Metal Products
