Hi Clifford
I am constantly looking around to try to find subjects which we have not
already covered.
We have in our data base a huge range Of topics, courtesy of Dave
compiling them on his Server.
Which folks can access to help them with completing their projects
successfully.
So I hope this one works for you.
Regards
Ray

Subject: [BlindHandyMan] Rooftop Moss Control
Q: What's the best method to remove moss from asphalt shingles
and prevent
re-growth?
A: Moss and lichen are both highly sensitive to zinc, and this
Achilles Heel
is the key to a fix. Up near the peak of your roof, install a
1-inch strip
of galvanized steel flashing or pure zinc strip underneath the
top course of
shingles. Allow 1-inch of this metal to remain exposed to the
weather. Be
sure you actually get hot-dipped galvanized steel for this job
and not the
more common aluminum flashing sold everywhere. As rain and melt
water
trickles down over the metal it dissolves small amounts of zinc
that kills
the current moss growth and prevent a reoccurrence. Sometimes
it's necessary
to remove existing lichen growth with a gentle pressure washing,
but the
zinc always prevents re-growth.
