[BC] Protecting the roof from ice.

[Chris R. Holt]

Years ago I did some work at a TX site on Mount Rose, just outside Reno NV.
Falling ice was *definitely* a problem for them.  The roof had a thick layer
of rubber, covered by concrete pavers.  The pavers were designed to be
sacrificial - they would absorb the energy of the falling ice and be
crushed, and the layer of rubber also absorbed additional energy while
protecting the building structure.
