Leaking Cement Flat Roof
Okay --- I have a cement flat roof -- and I have new roofing system of a simple rubber membrane/tar paper, all my neighbors have replacement roofs much the same--- but they all leak. We are townhouses and our roofs are enclosed by brick walls on all 4 sides......

I am looking for a product that will be both a foam insulation (as we have NO insulation) and a "regrading" tool --- something that can give a "slant" to my flat roof and help water rush off to the gutter.

Suggestions? Much appreciated!!!

SPF can do all of this, but R value mmay be negated for the living space if you have a cold roof assembly.
