Over time, moss growth can significantly compromise the integrity of your roof. As moss spreads, it traps moisture and causes shingles to lift, creating gaps that expose your roof to potential water damage, leaks, and moisture-related problems.

Along with moss, black algae, and lichen pose common threats to roofs, especially in the damp West Coast climate. Black algae leave unsightly stains that diminish your roof’s appearance and can retain heat, negatively affecting energy efficiency. Lichen, a combination of algae and fungus, can root deeply into shingles, leading to further deterioration over time.

To combat these issues, we offer professional roof treatment services. Our treatments effectively eliminate moss, algae, and lichen, protecting your roof and extending its lifespan. Given the frequent rainfall and high humidity in the region, roof treatments are essential for maintaining your roof’s integrity and ensuring your home remains safe and visually appealing.

Instead of replacing your roof, consider letting us wash it for you. While having a mossy garden on your roof may be a picturesque look typical of the Pacific Northwest, it is undoubtedly causing significant damage. The roots of moss grow between and beneath your shingles, compromising the integrity of your roof and creating areas of moisture that can lead to leaks and deterioration. The cost of roof cleaning is usually less than 5% of the price of a new roof, yet it can dramatically extend the lifespan of your roofing system. Keep your roof looking its best and preserve its health with our low-pressure roof cleaning services

Safe For Your Home

We start by gently brushing away the large patches of moss on your roof using a soft bristle brush. After removing the bulk of the moss, we apply a specially formulated chemical treatment that effectively kills any remaining organic matter and helps prevent future growth. This method ensures a careful and safe cleaning process and is the only technique recommended by the Asphalt Roofing Manufacturers Association. We do not use pressure or aggressive cleaning methods, as these can cause irreversible damage to your roof.

Warrantied Service

We offer a two-year green-free guarantee for all our roof treatments. This means your roof will stay free of moss, lichen, and other organic growth for at least two years after our service. If you notice any growth during this time, simply reach out to us, and we will take care of it at no extra cost. With our commitment to quality and customer satisfaction, you can trust that your roof will maintain its integrity and appearance, giving you peace of mind for years to come!

Asnew Exterior Cleaning did a fantastic job on our three shop and barn roofs. Levi came right out to make an estimate and followed up with prompt and clear communication to set up an appointment to clean and treat all our roofs. They were so careful around all our livestock, taking care to cover water troughs and picking up all the debris that came off our roofs. We highly recommend Levi and Asnew Exterior Cleaning.

Levi of Asnew Exterior Cleaning was a joy to work with. He arrived on time, was very professional and friendly. My two story barn roof was covered in moss. He removed all of the heavy moss and then sprayed the chemicals that would further kill the remnant. He raked, bagged and transported all the debris away. I highly recommend him to any one needing their roof or exterior cleaned. Thank you Levi, I wish you well in your endeavors.

Frequently Asked Roof Cleaning Questions

Why Is It Important To Remove Moss From My Roof?

Moss can retain moisture, leading to roof damage, leaks, and a reduced lifespan of your roofing materials. Removing moss helps protect your roof, maintain its integrity, and improve its appearance.

Is Pressure Washing Bad For My Roof?

Yes, pressure washing can be extremely damaging to nearly all types of roofs. In fact, using a pressure washer can void your roofing manufacturer’s warranty. That’s why we employ a low-pressure treatment process that is safe and effective, ensuring no damage to your roof while providing long-lasting results.

Is the Chemical Safe For My Plants And Landscaping?

Our roof treatment chemicals are designed to be totally safe for your plants and landscaping when applied correctly. We take great care to protect your garden and surrounding vegetation during the treatment process. Before application, we take precautions such as wetting down plants and covering sensitive areas to minimize any potential impact. However, it’s always a good idea to inform us of any specific concerns you may have about your plants or landscaping, and we will take extra measures to ensure their safety.

What Should I Expect After My Roof Is Treated?

After treating asphalt and tile roofs, you might notice some remaining white, dead moss. This is completely normal. Rather than removing 100% of the moss—which would require harmful methods like pressure washing or wire scraping—we use a gentle brooming technique to loosen the moss, followed by an application of our solution to eliminate any remaining growth. Over the next 3–6 months, the rest of the moss will naturally fall off, leaving your roof clean and well-preserved. This safe and effective approach ensures your roof remains in excellent condition for the long term.
