DIY Roof Cleaning Moss, Mold, and Algae

by admin on July 12, 2011 · 0 comments

A home's roof is absolutely vital as it protects your house from harsh weather and other environmental elements. In geographical areas that are often damp or have high humidity another enemy to a roof is the growth of algae and roof moss. Once it takes root on the surface, it seeks dark and moist areas in which to spread and grow. Structural damage does not occur right away but the roof's appearance can change fairly quickly.

Cleaning the roof with proper roof cleaning chemicals is by far the simplest way to get rid of algae, mold, or moss. This is particularly true if these culprits only grow in certain small areas of its surface. Roofs that are almost completely covered with mold however will be much harder to clean. Getting up on the roof's surface to combat algae and mold growth can be done on your own but can also be extremely dangerous since mold is very slippery and you're dealing with some pretty harsh chemicals.  Therefore in this case hiring a roof cleaning service is money well spent as they have the knowledge and equipment necessary to do the job properly and safely.  In addition, if they damage the roof in any way, they are liable for repairs whereas the do-it-yourself cleaner has to pay for any needed repairs that result from amateur efforts.

Sodium hydroxide is one of the key ingredients in mold cleaners. A chlorine bleach base is mainly used in commercial roof cleaning products. Both of these elements get to the root of the mold and algae to destroy them. If you are doing it yourself, be sure to wear safety masks and gloves when using any chlorine-based cleaners to prevent any harmful skin contact or breathing the fumes.

A homemade cleaning solution can be mixed using a quart of chlorine bleach and a gallon of water, with one fourth of a cup of trisodium phosphate stirred in. Put in a spray bottle to apply to small patches. For a larger, more involved surface area, pour the formula into a pump sprayer. After about fifteen minutes of contact with the offending growths, rinse the solution off the roof shingles. Clean off all that grimy mold for the best looking roof possible. Then keep a spray bottle handy for quick touch-ups.
