Z-STOP Is Easy To Use
®
A new roof is one of the largest single home
maintenance expenses you will face. If you're putting
on a new roof you want to make it last as long as
possible. If you have an old roof, you want to put off
repairs as long as possible. Z-STOP can help you do
both. goes a long way to greatly increase
the life of your roof - old or new!
®
Z-STOP
Apply Z-STOP by butting it up against the ridge cap
on both sides of all roof peaks (see image to the left).
Rain water must run off the ridge cap across the Z-
STOP and down the roof. Rain water must run over
Z-STOP to become effective. Apply Z-STOP below
anything that blocks rain water flow such as
chimneys, gables, and skylights.
Nail approximately every two feet with neoprene
washered roofing nails (included).
On roofs with moss or fungus, the existing growth
must first be removed by pressure washing or
brushing, then treated with a chemical to kill the root
systems. Then install Z-STOP to keep it from
growing back.

In areas of severe moss or fungus growth, several horizontal
rows of Z-STOP application may be necessary to assure its
effectiveness over the entire roof surface. Distance covered is
16-18 feet down the roof.

Don't Let Moss, Algae Or
Fungus Destroy Your Roof
Moss and fungus penetrate roof surface and
weaken fibers. Heavy build-up can lift shingles.
Both lead to shortened roof life..
Black patches discolor roof. Black color on your
cedar shingles is not “weathering” but algae.
Note how zinc washed down from galvanized
pipe has kept moss and fungus from growing.
