How do I clean existing fungus, moss or
algae off my roof? For pre-existing conditions we
recommend Shingle Shield Roof Cleaner, which is specifically designed to
clean roofs prior to application of the roof protector strips.
Other cleaning solution may not be effective against these organisms,
and my harm your roof or plants.

How much cleaner will I need to purchase for my roof? How do I apply it?
Generally, one (1) gallon will clean 2,000 square feet
when mixed at a ratio of 9:1 with water. Two (2) gallons are
usually sufficient to clean the average roof.
The diluted cleaner is best applied with a pump type gardens prayer,
starting at the bottom edge and working up the roof.

Will Shingle Shield Roof Cleaner harm my
landscape plants?
When properly mixed and applied according to
the label directions it will not harm your plants. Added insurance, it
is wise to thoroughly wet down your foundation plantings before starting
the application, and to rinse them again following completion.
|
How often should I apply Shingle Shield Roof Cleaner?
Once you have cleaned your roof, Shingle
Shield Roof Protector zinc strips should be installed to inhibit the
return of algae, fungus, or moss.
Stains caused by pollution, pine pollen, dirt, etc.., will need to be
re-cleaned as deemed necessary to maintain your roof's neat appearance.
|
Can I use Shingle Shield Roof Cleaner to
also clean my deck or sidewalk?
Absolutely!
Shingle Shield Roof & Deck Cleaner is the perfect solution to
restoring the appearance of wood decks, gazebos, fencing, or porches.
It will not lighten the wood's color (including cedar and redwood)
because it contains no bleach.
It is also ideal for cleaning most non-oil type stains from concrete
driveways and sidewalks. Properly follow all directions on the
label.
|
| Will one application completely clean my roof? You must first spray the darker
streaks that appear on the roof, then spray the remaining roof surface,
going over these darker streaks a second time.
Some severe stains may require a slightly higher ratio of water to
concentrate.
If in doubt, experiment with a small area of the roof, first stating
with the commended ratio of 9 parts water to one part concentrate.
Works your way up to a 6:1 ratio, which should only be used on the most
severe problem areas.
|
| What is the proper procedure for using
this cleaner on my roof? Apply the water and cleaner mix with a garden
sprayer. First thoroughly wet down the darker streaks, then spray
the remaining roof area going over the streaks a second time.
After 15 to 20 minutes you can begin to wash the cleaner and stains off.
Ideally, you should use a hose end high pressure wand (like the kind
used to clean siding); if you use a standard nozzle, adjust the nozzle
to it's most powerful stream setting. Depending on your water
pressure, hold the spray end as close to the roof surface as necessary
to dislodge the stains loosened by the cleaner.
Professional roof cleaners can expedite this process by using a power
washer with a maximum pressure of 500 psi.

On roof slopes longer than 20', or roofs with a sever or persistent
problem, install a second row halfway down the roof.
|
| I don't want to nail this product under my
existing shingles. Is there another way to install Shingles
Shield? While we cannot readily endorse any other
installation method, you may be able to attach Shingle Shield by using a
roof mastic (adhesive). The mastic is spread on both sides of the
Shingles Shield strip area that is designed to go under the shingle (do
not cover the area that is designed to be left exposed).
Slide the Shingle Shield strip in place under the shingle to its correct
position.
The installer must insure that it is properly held in place after
installation.
|
| Will Shingle Shield stay shinny? No. Shingle Shield will quickly weather
to a pewter gray. In addition, since only 2" of it are exposed it is difficult to see
from the ground. Remember, the alternative is an unsightly, badly
stained roof.
|
| Is Shingle Shield available in colors?
No. If we were to apply color to Shingle
Shield it would be unable to release zinc oxide - the active ingredient
that protects your roof.
|
| Will Shingle Shield ham my plants, animals,
or children? Shingle Shield is EPA approved and should be
used as directed in a manner consistent with the provided instructions,
and as such is considered safe.
Zinc is an essential element of the human body. It can be found in
vitamins, and as additive in breakfast cereals.
|
| How long will Shingle Shield last? Based on the thickness of the zinc that is
Shingle Shield, it is reasonable to assume that it will remain effective
in excess of 20 years. Climate may also be a factor in this
estimate.
|
| Will Shingle Shield stain my roof? No. The zinc oxide it releases is
microscopic and absorbed by the shingles. It is possible, although
unlikely, that the attachment nails will leave rust stains, we recommend
the use of quality, double hot-dipped galvanized roofing nails, such as
Maze brand.
