Green Chemical Roof Cleaning Products Green Chemical Roof Cleaning Products

Chemical roof cleaning is necessary when the roof has been stained with algae and rain. Although there are many products in the market that advertise effective roof cleaning, not all of them are safe to use especially when there are plants found at on the grounds where the water drains. When it is necessary to clean the roof, consider green chemical roof cleaning products.

First of all, cleaning the roof should be done safely without doing damage to the roof itself. Never use a power washer if the roof is not made of concrete. Pressure washer may wash off or damage the shingles so make use of a water hose instead.

How to Clean the Roof Safely Using Bleach

The most effective way to clean the roof is to use bleach. Chlorine bleach is a very effective product that can kill molds as well as remove tough stains. In order to use bleach effectively, mix one part bleach with one part water. Apply the bleach to the roof and allow it to sit on it for a few minutes. The bleach will loosen up the dirt and stains to allow easily rinsing afterward.

To add to the effectiveness of bleach, apply a cup of green detergent and apply it on the roof. The detergent will work on the grease and other hard-to-remove stains. To clean the chlorine and detergent residue, use a water hose instead of a power washer. Do use a power washer if the roof is concrete.

When using bleach solution, always make sure to wash off the chemical with water to make sure it does not affect the plants negatively since excessive exposure to the chemical is detrimental to plant life. Rinse off the chemical from the roof with water properly to ensure that the bleach does not corrode metals and other materials on the roof.

Although bleach is man-made and is categorized as a chemical compound, it is not entirely non-green. Chlorine, the major component of bleach, is a natural chemical. Bleach breaks down to salt, water and oxygen.

Using Sodium Hydroxide

Sodium hydroxide or lye is also a roof-cleaning ingredient that is also common in drain cleaners, oven cleaners and paint strippers. Although the chemical may be toxic to plants in excessive concentration, it is safer than bleach when rinsed well with water after application. When using this chemical in asphalt shingles, make sure not to apply the chemical excessively because it causes irreparable damage.

The chemical is also effective in removing algae from the roof. Although it is harder to remove from the surface of the roof, it is generally more preferred than chlorine bleach. To remove the chemical effectively from the surface of the roof, it is best to use pressurized water. If the roof is vulnerable to damage, make sure to lower the water pressure to avoid damaging the roof.

Greener Alternatives

The market is now filled with greener roof cleaning products that do not make use of either sodium hydroxide or chlorine. These products have citric acid, soda or borax as main ingredients; however, these products may take a longer time to remove the stains, but they are generally much safer to use.
