[GBlist] membrane for green roof

["Alan Abrams" <awabrams@starpower.net>]

this is the argument for fully-adhered membranes for
green roofs--that the leak will tend to manifest itself
directly below its occurance

< An earthen roof, properly constructed, will never
need repair in
<the waterproof plane.  However, in this real world,
sometimes roofs
<leak.  When that happens, it's extremely helpful to
know where.  If
<you have a layer of plastic on the underside of the
roof, then the
<leak will appear at the wall.  All that tells you is
that the leak is
<somewhere between the peak of the roof and the wall.
On the other
<hand, if your waterproof layer is immediately over the
decking, then
<the leaky spot will show right where it is on the
decking.  Easy.
