[TheForge] Update [OT - Asphalt shingle rot? (Lichen)]

[Mark A. Pesetsky]

OR....Grab a new 120 belt and throw it on the 2 X 72 and grind down a
batch of copper tubing and scatter as described below?

I cleaned out my metal cutting saw the other day and that brought to
mind another possible scenario for copper 'salting'.
  If you clean out your saw, mine is a Hitachi with a toothed blade BTW,
and saw up a bunch of copper scrap, collect the saw 'dust' and cast that
upon the roof there is a good chance that on a hot day it might just
melt into the shingles.
  If nothing else, the small particles might lodge into the shingles and
stay near the peak. The particles would be small enough that they would
not likely be disturbed by the wind... at least it wouldn't require much
work to place them.
