Roof discoloration is deceptive in nature in the sense that homeowners fail to identify the real causes behind black streaking or dark staining on the roof surface, typically on the northern and north-western exposures. What causes this wrong understanding of the problems plaguing the roofs of residential properties? Let’s look into the issue with some pearls of wisdom from the Roof Cleaning Institute of America. Causes of Roof Discoloration/Weakening The Roof Cleaning Institute of America (RCIA) says that many homeowners believe that dark staining is purely cosmetic. The RCIA calls it a “false” notion and goes on to state that microscopic bacterial spores that are typically carried by the wind land on the roof and begin feeding off the embedded limestone. “It gradually depletes the layer of granules that make up each shingle. As this happens, the roofing materials become less effective and ultimately result in premature shingle failure. If the bacteria is not properly treated and eradicated, you can lose 20-30% of useful life of the entire roofing system,” warns the RCIA. Solutions For Securing The Roof Roofing manufacturers, including ARMA (Asphalt Roofing Manufacturers Association), recommend that roofs be cleaned by a professional soft/power washing company. This recommendation comes in light of the fact that thousands of homeowners seriously injure themselves by personally attempting to perform maintenance works on their roofs. Don’t burn your hands, let the experts handle this situation. And when we say experts, we mean a professional soft/power washing company that has been certified and is fully insured.
Ineffective Results Versus Instant Results The RCIA says that there are many products in the market that claim to have the power to remove staining and bacteria. But the fact is that these products are “ineffective”. The results are short and generally cause the regrowth to be more aggressive. When your roof is cleaned by a certified professional, the results are instant and last for many years.
Don’t Throw Caution To The Wind The RCIA says, “You must avoid any contractors that use a high-pressure system to clean your roof. This type of system will not only cause extensive damage, but will also void any warranty that is currently held with the manufacturer.” We Are Here For You Absolute Clean Inc – a certified professional soft/power washing company based in Riverhead, Long Island, New York – can help restore the structural sanctity of your residential property by applying environment-friendly solutions with safe washing systems.
