[BC] Protecting the roof from ice.

[towers at mre.com]

At one site I consult, the tower accumulates a LOT of snow and ice during
storm events. The falling clumps of snow/ice are rather intense.  On
freshly fallen snow, the sound is quite intriging.  However, when the ice
really builds up, the falling ice impact makes the ground feel like a
small earth quake has occured.

There is a standing rule there which states "No one is to enter the rear
yard area without a hardhat during periods when ice and/or snow might
accumulate on the tall tower. If there is doubt about the conditions, what
ever needs to be done can wait."
