Of all the reasons you should clean your roof, none is as important as prolonging your roof’s lifespan. You may look at your roof and think, “Wow, it’s so dirty!” The truth is it isn’t that dirty at all.

It’s actually infested with a moldy bacterium known as Gloeocapsa magma, which is prematurely deteriorating your roof. Early deterioration means early replacement, which means giving up your hard-earned money before you should have to.


This mold weakens roofs several ways. Its filament root system burrows into the roof surface, causing cracks or fissures. The byproduct of photosynthesis that it excretes is highly acidic. Once the Gloeocapsa spreads, it allows colonies of even more aggressive bacteria — such as mold, moss and lichens — to thrive and expedite roof deterioration.


This is the darkening you see. It usually starts as streaking and quickly overtakes the entire roof. Once the roof is covered there is no protection from the UV rays of the sun.

This leads to another serious problem with heat. Because your roof is now darker, the heat it absorbs is significantly higher — in many cases, by 60 degrees or more.


This excessive heat is transferred into the attic space and bottom side of the roofing substrate, which, for asphalt shingle, will begin to dry out the petroleum base and lead to cracks and leaks. The heat that is trapped under the roof then begins to heat up with anything that it engages — including ducting, walls, pipes and ceilings — causing the home to be hotter and harder to cool, and making your A/C work extra hard.

This leads to higher energy bills and the possibility of having to prematurely replace A/C units. Every type of roof, whether asphalt shingle, tile, slate, wood, aluminum, galvanized and especially elastomeric coatings, will have a greatly reduced life if not properly treated and maintained.

Fortunately, Envirowash Hawaii LLC has the solution. Owner Mike Wedge said, “Simply pressure washing a roof does nothing to solve the problem. In fact, the use of a pressure washer is highly discouraged by the American Roofing Manufacturers Association and the roof-cleaning industry.


“Our revolutionary soft-wash process ensures that these organisms are eradicated and that there is no potential for damages caused by high pressure. When you compare the cost of premature roof replacement, along with increased energy bills, you will see that it doesn’t cost to treat your roof — it pays!”
