	Q & A Answers To Your Questions About Shingle Shield Maintenance-Free Roof Protector
Will Shingle Shield eliminate an existing algae, fungus, or moss problem?	When rain water comes in contact with Shingle Shield Roof Protector, a fungistat and effective drying agent is released, zinc oxide. This agent is meant to inhibit the growth of algae, fungus, or moss – not kill it.
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 solutions may not be effective against these organisms, and may harm your roof or plants.
Will one row of Shingle Shield protect my roof?	In most cases, one row at or near the ridge line will be sufficient to inhibit the growth of fungus, moss or algae. On roof slopes longer than 20’, or roofs with a severe 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 Shingle 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 Shingle 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 shiny?	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 harm 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 an 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 Mazeä brand.
Can Shingle Shield be used on wood shake roofs?	Yes. But be cautioned that Shingle Shield is designed specifically for use with three tab shingles. The installer assumes complete responsibility as to how to attach the product to a wood roof. The primary objective is to have rain water run over Shingle Shield, then onto the areas affected by fungus, moss, or algae.
Will Shingle Shield hurt my aluminum gutters?	This is a question about dissimilar metals corrosion. Zinc and aluminum are adjacent on the electro-chemical scale. The farther apart metals are on the scale the greater the likelihood that they will have an affect on one another. The fact that zinc and aluminum are so close indicates that there would be little problem, even if they were to come in direct contact with one another on the roof, which they should not.
	Q & A Answers To Your Questions About Shingle Shield Maintenance-Free Roof Protector
How much Cleaner will I need to purchase for my roof?	Generally, one (1) gallon will clean 2,000 square feet when mixed at a ratio of 9:1 with water. Two (2) gallons is usually sufficient to clean the average roof.
Can I use Shingle Shield Roof Cleaner on my wood shingles?	Yes. Shingle Shield Roof & Deck Cleaner effectively cleans away stains of algae, fungus, molds, mildew, dirt, pollution, pine pollen, berries, etc. Since it contains no bleach, it will restore the natural color to the wood. Wood shingles get slippery when wet, however, so wait until they are completely dry before walking on them.
Will Shingle Shield Roof Cleaner harm my landscape plants?	When properly mixed and applied according to the label directions, it will not hurt your plants. As a precaution, it is wise to rinse any overspray off of your plants to avoid spotting.
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 starting with the recommended ratio of 9 parts water to one part concentrate. Work 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. You may want to expedite the process by renting a power washer using a maximum pressure setting of 500 psi so you don't damage the shingles.
