My new (old) house has a roof deck with a pitch of 6" in 16 feet. There is a membrane or hot mop surface, 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!).
There were some leaks when we moved in and I pulled up one of the sections and used a quart of trowel-on repair material and that stopped the current leaks. I noticed that the styrofoam was completely waterlogged, and it weighed a lot!
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 are:
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?
I'm somewhat impressed with this roof - seems like the styrofoam protects the membrane, and the bricks protect the styrofoam.
Thanks for any suggestions!
