What about "Foam roofing"? Where they spray foam on top of everything?
Is that a scam?


Hey Iggy,

The foam is for insulation ONLY. It W I L L float off if it
isn't under the sealing material, or buried in stone.

And I recall going to a fairly new apartment building with new flat
roof where they had laid that 3" thick X 24 " X 48" fairly hard blue
insulation on top of the sealing stuff (sheet rubber???), and then
laid patio stones on top. The whole roof was floating around and the
wind had it crashing into stack vents and such. It was scaring the
tenants, and the building manager was scared of going up on the roof,
so he decided it must be one of the elevators and called me.

Take care. Good luck.

ps...I think your first idea about adding a drain is a good idea.
