Im moving to Florida, and, bought a Mobile Home which of course has no
attic. It has a southern exposure with no shade and im wondering what
options are available to reduce the Cooling Load on the roof. Ive
wondered if a metal pan roof can be put over an existing shingle roof
(or just adding large sections of sheetmetal on the roof) , thought
of collecting rain water in a 55 gallon drum and pump it up to the top
of the roof and let it run down thru a PVC pipe with holes drilled
into each side , and have even considered putting in an additional
ceiling inside and insulating that cavity . Has anyone had success
with this issue or can tell me whats an effective solution ? Thanks
much.

A good many folks here build a carport looking roof over the mobile
home.
That puts the entire roof in the shade.
