My new (old) house has a roof deck with a pitch of 6" in 16 feet.
There is a membrane or hot mop surface,

Which is it?

on top of which are 4 x 8
foot panels of what looks like styrofoam, covered by a herringbone
pattern of brick like pavers (they look like bricks, but are less
than half the thickness and presumably weight!).

I'd like to shape up the roof by taking up the bricks, then the
styrofoam, applying something in the way of do-it-yourself (mop on?)
stuff ( I have in mind something like driveway renewer, but
obviously something for roofs!)

SO my questions a

1) What can I replace the styrofoam with that won't absorb water?
2) What should I mop onto the roof that won't overwhelm the average
handy homeowner?

Around here, (Florida) tile roofs have a layer of 90# roll roofing material
over the roof sheathing and dry in felt. It is applied over and embedded in
tar that is mopped on hot. It is the *real* roof, the tiles are cosmetic
(as far as preventing leaks go) and are mudded onto the 90#.

Some people attach battens to the roof and nail the tiles to the battens.
Personally, I don't like that as water that comes through the tile joints
can be trapped by the battens. Moreover, nails make holes through the 90# -
the real roof.

I'm somewhat impressed with this roof - seems like the styrofoam
protects the membrane, and the bricks protect the styrofoam.

I would think that the styrofoam is for insulation, not protection of the
membrane. You could skip it and insulate the underside of the roof.

Thanks for any suggestions!

IMO, mopping on hot tar isn't a DIY project. Nor is mudding on tiles or
"bricks". Especially the former.
