Various Florida residents that contain range from North are amazed by the idea of roof cleaning – and even more surprised by the simple fact that many residential areas here in Florida require it. Reasons for cleaning include aesthetics, property principles, energy efficiency, and increased longevity of the roof structure. roof cleaning Geelong

Whatever the key reason, if it is going to be done, it is your very best interest to really know what choices are available to you. A quality roof top should last upwards of 3 decades if cared for and maintained properly. Unfortunately, many roofs here in Florida (and progressively throughout the US) are subjected to unnecessary stress while cleaning the greatly reduces the life span of the top. With repeated roof cleaning comes certain pitfalls that all property owner, property manager, and professional cleaner should be aware of in order to avoid harm to property, needless repair costs, and the premature replacing the roof top.


The dark streaking typically found on homes in areas where moisture settles on shingles is not caused by mildew or fungus; it can roof algae. 3M experts have discovered the most frequent form as Gloeocapsa Magma. Wrack spores are carried n the wind, which is why so many residences in the neighborhood can wrap up with this problem. Over the last 20 years, this particular dirt strain has become tougher and so has recently been able to migrate to less humid environments than it has in the past. And in locations where it traditionally has been found, the discoloration is showing up before, is more severe and settles on a better number of roofs.


Typical roof cleaning methods involve either pressure cleaning or chemical solutions made up of Chlorine Bleach or Salt Hydroxide. If used properly, these methods will clean the roof with nominal adverse impact – but the effects can be very momentary and will generally have to be repeated every 6-18 several weeks to be able to maintain the appearance of the roof structure.


Every method has its pros and cons.

A chlorine and drinking water solution can be used then a thorough rinse out. Of course, since chlorine can be toxic to people and plants, care should be taken to protect employees and the surrounding property from overspray and runoff. The huge benefits to using chlorine incorporate a much faster cleaning process and minimal rinsing as as opposed to other methods. This kind of translates into a lot less wear & tear on the top – particularly concrete shingle roofs.

Sodium Hydroxide based cleaners are generally advertised as safer for the landscaping, but salt hydroxide is caustic, very toxic, and care should also be used to safeguard employees and surrounding property. Sodium hydroxide is the very effective degreaser. Therefore high numbers of sodium hydroxide in a cleaning product can damage an concrete shingle roof that can be irreversible. These products generally require much more rinsing than the chlorine method. The rinsing process is not only time intensive, but it can even be possibly damaging to the roof structure if not done properly. A good sodium hydroxide centered product should not require any more than 90 psi to effectively wash an asphalt shingle roof structure and even then some granule loss should be expected.

Pressure cleaning is an option that should only be applied to a concrete, barrel tile, or metal roofs. Pressure cleaning has the good thing about not requiring chemicals, which gets rid of some of the cost – in addition to landscaping and chemical coverage concerns. The problem with this to pressure cleaning is the fact it is very time consuming and it exerts tremendous force on the surface that is not really created to handle it. In addition, repeated pressure cleaning can wear away the surface of some tiles that are only have a thin level of coloring. During these moments, the grey concrete color starts off to show through and the top must be stained or painted.
