Roof Cleaning – Making Your Old Roof Look Like New!

Quite a few Florida residents that have come from the North are surprised by idea of roof cleaning – and even more surprised by the simple fact that many communities here in Florida require it. Reasons for cleaning include things like aesthetics, property values, energy efficiency, and increased endurance of the roof.

Whatever the main reason, if it is going to be done, it can be your best interest to know what choices are available to you. A top quality roof should last upwards of 30 years if cared for and maintained properly. Unfortunately, many roofs here in Florida (and increasingly throughout the US) are subjected to unnecessary stress even though cleaning the greatly reduces the life expectancy of the roof top. With repeated Roof cleaning cape coral fl comes certain pitfalls that homeowner, property manager, and professional cleaner should be aware of in order to avoid destruction of property, unnecessary repair costs, and the premature replacement of the roof.


The black streaking typically found on homes in areas where moisture settles with shingles is not caused by mildew or fungus; it’s roof covering algae. 3M scientists have identified the most common form seeing that Gloeocapsa Magma. Algae spores are carried b the wind, which is why so many houses in the neighborhood can end up with this challenge. During the last 20 years, this particular algae strain has become hardier and for that reason has been able to migrate to less humid environments in comparison with it has in the past. And in areas where it traditionally has been observed, the staining is showing up earlier, is more severe as well as settles on a greater number of roofs.


Typical roof cleaning methods involve either tension cleaning or chemical solutions containing Chlorine Bleach as well as Sodium Hydroxide. If used properly, these methods will probably clean the roof with minimal adverse impact – even so the effects can be very temporary and will generally have to be repeated just about every 6-18 months in order to maintain the appearance of the roof.


Each method has its advantages and drawbacks.

A chlorine and water solution can be used followed by good rinse. Of course , since chlorine can be toxic to people and also plants, proper care should be taken to protect employees and the surrounding property from overspray and runoff. The benefits to employing chlorine include a much faster cleaning process and minimal rinsing as compared to other methods. This translates into much less wear along with tear on the roof – particularly asphalt shingle roofs.

Salt Hydroxide based cleaners are generally advertised as safer for any landscaping, but sodium hydroxide is caustic, very deadly, and care should also be used to protect employees and encircling property. Sodium hydroxide is also a very effective degreaser. So high improved sodium hydroxide in a cleaning product can cause damage to the asphalt shingle roof that can be irreversible. These products generally involve much more rinsing than the chlorine method. The rinsing practice is not only time consuming, but it can also be potentially damaging to the ceiling if not done correctly. A quality sodium hydroxide based solution should not require any more than 100 psi to effectively wash it out an asphalt shingle roof and even then some granule decline should be expected.

Pressure cleaning is an option that should only be officially used on a concrete, barrel tile, or metal roofs. Tension cleaning has the advantage of not requiring chemicals, which eradicates some of the cost – in addition to landscaping and chemical subjection concerns. The down side to pressure cleaning is that it is rather time consuming and it exerts tremendous force on a surface that is not really designed to handle it. In addition , repeated pressure clean-up can wear away the surface of some tiles that happen to be only covered by a thin layer of coloring. When this happens, the dull concrete color starts to show through and the roof need to be stained or painted.


While these methods are relatively safe and effective when performed properly, repeated use will lead to premature aging with the roof. The natural erosion that occurs over tie from basic forces of heat, cold, wind, and rain solely are enough to weaken most roofs to the point where 12-monthly inspections and minor repairs are necessary to prevent significant restore costs. But when the roof is repeatedly subjected to high pressure or simply harsh chemicals, the aging of the roof structure is significantly sped up. With repeated cleaning, tiles are more likely to shift, slip, and also break and asphalt shingles are more likely to become brittle along with crack. When this happens, there is a greater likelihood of tearing the roof couenne simply by walking on the roof. Once gaps are created in the top and subsequent pressure cleaning or chemical cleaning comes about, these gaps provide the water or caustic solutions a new path to the roof membrane and increase the chance of costly roof leaks.


A proper program of preventative routine maintenance will eliminate the need for future cleaning and the potential for deterioration that comes along with it. Preventing the recurrence of the herb growth will require a light spray of chlorine and waters or an algae prevention product.

Most quality algaecides will last for approximately 6-12 months before reapplication of the system is necessary. Obviously, the longer the time frame, the better your chances are of minimizing and unnecessary damage to the roof. Protection programs should be done in conjunction with neighbors whenever possible and plenty of can be applied without a need for walking on the roof.
