Why a metal roof is the best first start for a green house

People think metal roof are to expensive and while there twice the expense of a new shingle roof it simply not. 

As a shingle roof lasts in Florida no more the 15 to 20 years while a metal roof last a 100

Wind loads are critical as we do live in a hurricane state. shingles 110 if installed perfect and degrades every year which is why citizen fail roofs as young as 8 years and why so many  Polk county roofs were blue tarps with several cat 1 passing over them in 2005 to 2007 wile metal roof can be 145MPH as mine to 165 at the top end and that for the 100 year file of the roof.

 Energy savings all metal roof with white surface not only reflect heat they come with one inch to 4 inch's of marine foam like mine and it dropped our houses electric bill by 30 dollars a month

 So I now have solar hot water and soon PV solar which will take this house much closer to carbon neutral.

Thus thanks to my metal roof I never have to tear that off to replace the roof like people with shingle
