Why Is Keeping My Roof Clean Important?

Who thinks about cleaning their roof?  Until recently not many people have ever considered cleaning their roof.  The main reason is for looks.  Regardless of how nice your home or landscape, an ugly stained roof can subtract all of your efforts.  Insurance companies also make people clean their roof.  Most stains on a roof are organic and feed on the limestone in the roofing shingle.  Stained roofs essentially have become a sort of petri dish.  Plus, moss and algae can create a slippery atmosphere which creates a liability for the insurance company.

Your roof is probably the most expensive item of your home.  When it comes time to clean it you’d better be aware of the damages that are associated with using high water pressure for roof shingle cleaning. Though most people consider it a cleaning, we look at it as a treatment, or “pest control”. The difference is that the term “cleaning” is all about “perception”. Something can appear “clean” but may not necessarily be sterile.  The goal of a roof treatment is complete and absolute sterilization of the organism that are staining the roof.

“Low-Pressure” Roof Power Washing Is Not Good

 The problem with using any type of pressure is that high pressure water will dislodge the roofing granules. Those that did not fall off immediately are now loosened and will rinse off more and more with each rain. if you’ve ever cleaned out a gutter you may have noticed roofing granules inside the gutter. This is what falls off naturely with rain, so imagine what even low pressure can do. Forget about high pressure!
Black streaks on a roof is actually a type of bacteria that feeds on the limestone in the roofing shingle. Stains can be seen primarily on the north side of the roof with less sunlight. These stains can be removed instantly with a non-pressure treatment using sodium-hypochlorite (bleach) and water combo with a surfactant to allow the detergent to cling to the roof. With this method you can achieve a 100% kill ratio creating a longer lasting clean. This is the recommended method by both major roofing maufacture GAF and the ARMA.

Roof Moss Removal | Do Not “Pressure Wash” Moss

When it comes to moss and other heavier growths, the results are not as immediate. After treating the moss it will turn biege and die. The ingredients of the roof detergent shock the root system, allowing it to detach from the shingle on its own. The dead moss will eventually dry out and fall off with rain. Regular moss growth can take anywhere from 4-8 weeks to be completely removed. Heavy moss can take up to 12 weeks. It’s a hard sell to customers because many times they are looking for instant results possibly for home sale.
