A dirty roof is not just an eyesore but the grime and debris can cause damage. It is therefore essential to clean your roof regularly. There are a variety of different methods that can be used, some of which are more effective than others depending on the extent and type of dirt that needs to be cleaned off.
Moss, algae and mold can be problematic as can black stains that are caused by water runoff. While many roof cleaning experts will tell you that a pressure sprayer is the way to go to resolve all of these problems, this is not actually the ideal way to clean a roof. A pressure sprayer can be very damaging removing the granules from your shingles or tiles and even lifting the tiles clear off the roof.
It is therefore better to select the right cleaning detergent for the job and use the correct cleaning technique depending on the type of dirt that exists on your roof. There are a range of different chemical detergents that are designed specifically to clean roofs. However, some are better than others and it is best to select a cleaner that comes highly recommended for a specific type of problem.
Follow the instructions on the bottle or simply mix up a solution and spray directly onto the roof. Leave the chemicals to work. There is no need to rinse – the next rain will take care of that. For really dirty roofs, use a broom to scrub it and loosen up the dirt after applying the chemicals and giving them time to work.
In extreme cases, a high pressure washer may be the only option. It is recommended to use the washer after giving a chemical roof cleaner some time to work and set it on the lowest pressure setting. This may mean that it could take a little longer to clean your roof but it will save you some damage in the long run as well as ensure that the job is done right.
Alternatively, you can hire a roof cleaning expert to take care of the job for you. The professionals in the industry have all the right tools and equipment to get the job done fast and the know-how to use the right technique and cleaning agent to ensure an effective cleaning solution. Remember to get references or referrals to ensure that the contractor is reliable, reputable and won’t cause damage to the roof resulting in leaks and other problems.
