Roof Cleaning and Pressurewashing

Roofs are considered horizontal flat surfaces and since they cover a large square footage area you will need a sophisticated gear in order to make your pressure washing job fast and efficient. The most commonly used device for this kind of application is a Flat Surface Cleaner. For roof power cleaning we recommend 20" pressure washer surface cleaner and/or 24" pressure washer surface cleaners.

Besides pressure washer surface cleaners, the great tool for cleaning roof is the pressure washer. These versatile units are capable of powerwashing any environment and are masters in removing any kind of dirt known to us. If you are in finding out what what kind of gear you need in order to perform powercleaning in a fast and efficient way, go to our pressure washer selector guide.

House and building roofs are one of the hardest surfaces to pressure wash. The biggest enemy of roofs is the black fungus. Fungus in general feed on moisture and nutrient and if the roof is surrounded by trees, lake or a pool and if outside weather is humid and warm, fungus will grow and spread rapidly. As a result, the fungus will deteriorate the quality of the roof and it will also make it look old and hideous by turning it into a dark and/or totally black surface.

The roof covered with fungus will absorb more heat due to its black pigmentation. Such hot roof surface will relay the heat through the ceiling into the residential home, office or other type of building causing the increase in room temperature. These factors will result in higher utility bills. Also, the presence of fungus in close proximity to a living environment can create health problems to younger children and those with allergy problems. In some instances, fungus can cause other problems by spreading through cracks and splits into a residential area.

Experienced pressure washing workers know that asphalt shingles, slate (old stone), and wooden shakes are popular in the Northeast regions and that in the Southern states the most popular materials for roofing are cement tiles, barrel tiles, finished and unfinished mansards, wooden shakes, metal, and asphalt. Because of the continuous high temperatures and humidity throughout the whole year, the majority of roofs in the southern states need to be cleaned every few years. Depending on the weather conditions the cleaning periods for northern states can sometimes be longer. Many pressurewashing contractors use bleach or chlorine as a main cleaning solution for removing mold and fungus. Even though those substances will remove dirt, they will create problems to other surfaces. They will brighten brick creating different color shades, and they will also kill the plants surrounding the object being cleaned. Bleaches will kill fish or marine life and will turn the cement into sand over repeated use. In addition, the bleach or chlorine will rust all the metal parts on a house such as gutters and vinyl siding.

There are two phases to pressure washing roofs. First is when you will use a flat surface cleaner for mold and fungus removal and the second is when you will use your pressure washer in order to rinse and clean up the mess. Surface cleaners are primarily used for washing flat surfaces such as concrete, side walks, parking lots and other. In case you have an asphalt/shingles, DO NOT use the surface cleaner, rather use a cleaning solution and the 40 spray nozzle to gently remove the dirt. Surface cleaners have 4 to 5 times faster cleaning times then the single wand. If you have a cleaner that has wheels – remove them. This will allow you to move freely without any worries about having one of the wheels getting stuck. Many professional power washing businesses use pressure washers that can produce hot water. If you prefer faster cleaning times consider buying a hot water power washer.

Attach the pressure washer hose to your surface cleaner, put your favorite chemical into the chemical injector container, turn on the engine and you are ready to go. Our chemicals has been proven to be safe, effective and trusted by satisfied customers. Our powerful, yet environmentally safe soap is used to dislodge the fungus so it can be easily flushed from your roof without damaging the integrity of the roof. The best place to start with the pressure washing process is one of roof corners. Move your equipment sideways (right to left) cleaning 3 to 4 feet wide areas in one movement. For tough stains use more detergent and more water. If necessary, move the surface cleaner over the same spot several times. If you are powerwashing on a hot sunny day, rinse the clean area with plenty of fresh water. Do not miss to do this every 10 to 15 minutes. When you are done with the entire roof, rinse the whole area with a lot of clean water. And that is the phase two. If you notice any spots that were missed during phase one you can wash them during this phase. Make sure to use cleaning chemicals so that you reduce the total cleaning times. Also, when buying a cleaning substance check to see if the solution is power washer approved. Non-approved chemicals will damage the pump, seals and other components.
