How to Clean Flat Rooftops

flat roofing

Flat top roofs are most often covered with rubber membrane. This is a highly resilient and waterproof covering that is very effective at holding out water, even when it pools at the surface. However, allowing water and debris to sit at the surface for too long can leave the rubber membrane susceptible to damage.

The most frequently noted problem atop flat rooftops is algae. The plant life loves damp, cool areas, which means that it is most likely to grow on areas of the roof that are well shaded. Mold is also likely to grow in these areas, which is another of the reasons why you or your Dallas roofers should regularly clean the surface and you can get that professional help; just click here. To make matters worse, the shaded areas are the most likely to be damp because morning dew would take longer to dry without the direct rays of the sun. Stagnant water can provide the ideal environment for all sorts of bacteria and harmful microscopic organisms, so you should take extra care to keep the surface clean if residents of the building frequently visit the roof.

Pressure Cleaning Fortunately, cleaning a flat top roof does not have to be overly difficult. It requires only some pressurized water, in many cases. Gas-powered machines are easy to come by. Renting is always an option, but as the owner or manager of a flat topped building, it may be smarter to simply invest in one of your very own. They can be purchased for about two hundred dollars at home improvement stores. The prices do vary with some models offered for a slightly smaller price tag and really nice models costing a bit more.

To begin cleaning the surface, start in a far corner and use an angled tip. This allows for easy washing of the flat surface. You will probably want to be dressed appropriately, because you are likely to get damp in the process as well. Keep the tip about six inches from the surface as you sweep over it. This will wash away algae, mold, and dirt in no time. To remove any water left sitting on the surface after cleaning, consider the use of a wet-dry vacuum.

Chemical Cleaning It’s not as environmentally friendly as straight water, but at times there is a need for a more thorough cleaning. For this reason, many are forced to turn to Sodium Hydroxide.

Sodium Hydroxide, which is also known as lye, comes in a few different varieties – pellets, flakes, and small granules. For cleaning purposes, like this, manufacturers also off a diluted, liquid solution. The chemical is regularly used in the making of paper, textiles, and soaps, among other things, but it is not something that should be handled lightly.

Sodium Hydroxide poisoning occurs too often in this country. Lye is found in drain cleaners, hair straighteners, oven cleaners, and metal polish as well as being used as a roof cleaning agent. When ingested, it can cause almost immediate symptoms including difficulty breathing, sneezing, throat swelling, burns to the skin, and pain in the throat and face. After a short period of time, the victim will find blood in his stool, vomiting, abdominal pain, fainting, and low blood pressure. Accidental contact with the chemical or ingestion is potentially fatal and time should not be wasted if it does occur. Contact with bare skin or eyes should be carefully avoided.

As a result of the danger involved, it is best to let the professionals handle cleaning with sodium hydroxide. Everyone involved should be covered head-to-toe and should wear a mask and goggles to defend the body against any possible contact with the substance.
