So, it sounds like the key indicators are:
a) does the tile still have coating on it? (ie-not smoothed, but still
bumpy with little grains)
b) are tiles flat? not curving, etc.
Also, from the inside, the decking looks good. I don't see any stains
or leaks, but is this test realiable as the damage would be on the top
of the decking?
