[Greenbuilding] [BULK] Water Damage

[Lawrence Lile]

This gets me thinking about my own building.  I have a metal roof, and
after watching widowmaker chunks of ice sliding off, banging up against
my AC compressor and smashing my plants last winter, I've ordered a snow
guard to be put in on the edges.  Am I inviting ice damming, and
subsequent roof problems by doing this?
