A moss-covered roof left untreated, is unsightly. What’s more, it compromises the integrity of your roof, degrades the shingles, and shortens the overall lifespan of your roof. When moss grows on the roof, it roots itself into and under the shingles, causing granular delamination, traps moisture that could result in leaks and mold growth, and can cause shingles to lift to let water and wind in. That’s where we come in.

At Moss Busters, we’re dedicated to providing a comprehensive solution to rid your roof of moss, protect its integrity, and maximize its lifespan. With over a decade of experience and thousands of successfully treated roofs, you can trust that your roof is in capable hands. Our signature approach, known as “The Moss Busters Method,” is specifically tailored for composition shingle roofs. By incorporating the most effective elements from various roof cleaning methods, we have created a unified approach that delicately yet thoroughly cleans your roof, safeguards its integrity, and ensures lasting protection.

The Moss Busters Method:

Our process begins by gently brushing off the larger clumps of moss from the edges of the shingles. This ensures we take the bulk of the debris off the roof in as dry, minimizing any mess around the property. Next, we apply a liquid detergent to your roof. This runs down the roof, penetrates, and kills the remaining stubborn moss that we were not able to brush off. After a short wait, we will perform a high-volume wash of the roof off with our truck-mounted setup leaving your roof looking and performing like new.

We follow up with removing any debris in the gutters and clearing the downspouts. To ensure that your roof stays in the condition we leave it in, we will apply a moss-preventative treatment that will stop future moss growth.

Upon completion of the cleaning process, we ensure all affected surfaces are cleaned, debris is hauled away and properly disposed of, and your property is left in better condition than we found it.
