Tools needed: Hammer and Scissors |
- On roofs
with moss, algae, mildew or fungus, the
existing growth must first be removed (by
pressure washing or brushing), then the
root systems must be chemically treated
and destroyed (see magazine articles for
bleach solution). Install Z-Stop zinc strips
to keep it from growing back.
- Apply Z-Stop zinc strip
by butting it up against the ridge cap
against both sides of all roof peaks (see
graphic). Apply Z-Stop below anything that
blocks rain water flow such as chimneys, gables and
skylights. Rain water
must run over Z-Stop to become effective.
- Nail Z-Stop zinc strip
approximately every two feet with neoprene washered roofing
nails (Z-Stop Nails included in each
roll).
In
areas of severe moss, algae, mildew or fungus
growth, several horizontal rows of Z-Stop
application may be necessary to assure
its effectiveness over the entire roof
surface.
