Using a deck cleaner as a shingle cleaner has been thought of as a better alternative to some of the more dangerous cleaning agents that are available.
The Pros of Using a Deck Cleaner on Your Shingles
One of the best deck cleaners available is oxygen bleach. Bleach in any form is not thought of as being green. However, oxygen bleach is made from raw materials that are food grade organic chemicals. Even with its green properties, oxygen bleach is an excellent and powerful cleaner that comes mostly in a powder form. Oxygen bleach in its purest form is made of hydrogen peroxide and soda ash. Once you mix the powder with water, you get even more water, oxygen and soda ash. The chemical soaks down into the wood and the oxygen then cleans the wood removing the elements of dirt, algae and mildew deep in the wood.
This action is excellent for your shingles as well. Although it doesn't have to travel as deep into your shingles as it does the wood, oxygen bleach is still able to remove the those hard to remove stains, moss and mildew particles from the surface of your shingles. If you have light colored shingles and have rust stains from nails running down your roof, an oxygen bleach cleaner is capable of removing the rusted stains.
The best thing about using an oxygen bleach cleaner is that it is non-toxic. No harm can be done to you or your plants and shrubbery if the cleaner comes in contact with them. Oxygen bleach is unlike chlorine bleach whereas you will have to ensure you are outfitted with protective gloves and eye wear. You will also have to ensure your shrubbery is covered with plastic or wood to keep the chlorine bleach from destroying them.
The Cons of Using a Deck Cleaner on Your Shingles
Although oxygen bleach is an excellent cleaner, it will still require a bit of scrubbing to remove stubborn stains. Because your shingles are made of asphalt and gravel granules, scrubbing a particular area too hard will cause the granules to become loosened and expose the surface they were designed to protect. This allows the excelled growth of mildew and moss on the exposed areas of the shingles.
The oxygen bubbles have deep penetrating properties. This is good when you are cleaning your wood deck. However, on your shingles, it can pose a serious issue if the roof is not rinsed properly. The oxygen bleach will continue to work on your roof eating away at dirt and the shingle itself. Should the roof not be rinsed thoroughly and a rain comes after a week or so, the oxygen bleach is further inclined to work by interacting with the rain water.
