Mold, mildew, lichen, moss, algae and sometimes small trees, all are happy to grow on the ideal surface of your roof. Sunshine, warmth, rainwater and fresh air all contribute to happy and fast growth of these nasty invaders, and result in a stained roof. Overhanging branches, sap and just general dirt and toxins add their additional layer of moss, lichen and sticky, dark stains also.
The coatings and stains mentioned above all contribute to the ultimate demise of your roof! If left unchecked, not only will the problem become more unsightly, but it will literally eat at your roof, eventually causing leaks and rot. Buildup of mold, mildew, lichen and moss on your roof can also affect the energy efficiency of your home which will cost you more in both heating and cooling. Dirty roofs should not be taken lightly, but should be a warning that it is time to clean up your act – your roof act, that is.
First and foremost, cleaning a roof is NOT a DIY job. No matter how simple the professional YouTube visuals make it look, that is exactly what they are: professional technicians being filmed at what they are trained for. Professionals know each step of the process, know their equipment, are familiar with various surfaces and are trained in safety. They make a tough and dangerous job look easy. Don’t be fooled into thinking it is as fast and easy as they make it look.
The cleaning solution we use actually kills the spores of mold and mildew. Water cannot kill those ugly spores and high pressure alone, while it can blast some of the spores away, not only does not kill the spores, but will also damage your roof! This specialized roof cleaning solution kills the spores which then loosen from the surface of your roof allowing them to be rinsed away. This is roof cleaning service at its finest and the stellar results of our roof cleaning service providers cannot be achieved with high pressure washers, untrained rookies or just water alone.
The procedure is simple. A coating of the chemical solution is swept over the roof in large, wide sweeps. The chemical cleaner is allowed to sit on the roof to loosen dirt and kill mold, mildew, lichen and moss. On a large roof, the technician may work on the roof in sections, which allows them to return to the beginning section and respray the solution within 3- 10 minutes of the first application. This respraying achieves two things. First, it rinses off the first of the dead mold and mildew spores, while secondly, at the same time laying down another layer of cleaning solution. The next section of roof is then ready for the second coat of solution as well as the removal of the top layer of dead mold and mildew. The technician works his way around the roof in sections (if needed), going back to respray where stains and discoloration may be darker or thicker.
Small roofs can be done all in one go. The technician can spray a whole roof and then go back to the beginning to add another coat of the solution which at the same time also removes and rinses off the killed mold and mildew spores as well as the loosened dirt. The second coat of cleaning solution is usually all that is needed to complete the cleaning cycle. Some roof types will be rinsed off with fresh water, while others can have the remaining solution left to safely dry on them. While on the roof, gutters are cleaned and constantly rinsed with fresh water, and chimneys are cleaned also.
This low pressure, cleaning solution method is perfect for all types of roofing.
While metal roofs look like they would be simple to clean with just a hose, this type of roof is the most dangerous to be on. This surface gets extremely slippery when wet (some technicians say it is like being on slick ice), so do NOT attempt to clean them yourself. Even with the smooth surface of a metal roof, mold and mildew get a foothold and discolor this roof. Note also that mold, mildew and algae are all also slippery when wet!
It is imperative that the right equipment be used to clean your roof and that the technicians using it know all the safety procedures. Your handyman may have a high pressure washer, but it is exactly the type of equipment that will damage roofing. In addition, your handyman probably doesn’t work with his pressure washer at heights very often, and so from the very start, he’ll be at a safety disadvantage. You need to call a professional roof cleaning service or power washing service to really get your roof clean, and to clean it safely without damage from the wrong equipment and the wrong approach.
