[SML] roof question

[Stephen Rees]

I don't know a whole lot about commercial roofing, but having watched
several go on the main stage and auditorium areas at the university over
the years, I might suggest one comprised of 4-6" foam or mineral wool
sections that taper towards the roof drains followed by a glued down
elastomeric sheet material.  There is lots of research out there on line,
but I would get a good roofing consultant - the a potential installer - to
give you better ideas for the amount of funding you have. I would have
concerns about sound issues with only 2" of foam. Even with as much as 6"
in some areas of ours, you can definitely hear heavy rainfall.
