You may have noticed dark patches on your roof, and that’s why you’re here. No worries, ORC Pros is ready to help. Olympia’s humidity and constant dampness often leave behind moss and debris, and while rain may wash away the moss, it leaves stubborn stains that harm shingles and ruin curb appeal. These stains can stay for years if ignored, so removing them early is key to restoring your roof’s shine and health. Our expert cleaners use biodegradable, harmless cleaning solutions to safely eliminate stains from any surface. Whether your roof has a small patch or widespread discoloration, we have flexible plans and offers to fit your needs. With over two decades of experience in roof cleaning service, stain removal, moss cleaning, and gutter maintenance, ORC Pros brings expertise, care, and lasting results to every home.

Algae growth, moss and lichen, scorching summer sun, dirt, leaves, needles, and pollution you have many enemies outside that leave their marks on your valuable property. Algae grow on roof surfaces due to humidity and dampness that nourish the green substance throughout winter. Even when removed, they leave dark marks, especially on wooden shingles under the summer sun.
Moss and lichen are also major culprits. Moss accumulates and spreads across surfaces, leaving stains once dried or washed away. Leaves and needles, blown by the breeze in shady neighborhoods, can also cause visible stains. When these remain until rainy seasons, the decaying leaves create hard, stubborn marks that can’t be washed away. It’s always good to remove leaves from the surface in late fall to maintain the beauty and health of your roof.
Like every cleaning process, we tackle the roof stain removal process with care and precision. We employ Soft washing for normal stains, pressure and chemical washing for stubborn stains, and brush cleaning for stains that are in corners, untouched for years.
On Asphalt, Wooden, and rubber shingles, we often use soft washing for stain removal. First, we spray the biodegradable, harmless, and decomposable cleaning solutions like Sodium Sulfate and Zinc Sulfate on the surface, and leave it for half an hour or more. The solution mixes with the stains and solves the grime within itself. Then our expert cleaners wash the surface with low-pressure water that leaves the surface shining.
On metal surfaces or stubborn stains that haven’t been touched for years, especially in the cervices or corners, are washed using Brush Washing and Pressure Washing techniques. This one is also similar to the soft washing, only the stains are rubbed by a stiff brush, or pressure water is applied, mostly on the metal surface, to restore the shine. Our experts use this technique when needed, not so often.
Roof stain removal services not only restore the lost glory of the shingles but also improve the curb appeal of the property. Moreover, it lessens the impact of dust and spores from impacting your nostrils and lungs. A minimal investment in roof stain removal brings a lot of value to your property. It also prevents the roof from long-term damage, as a risk of a few stains damaging the surface of the shingle, especially wooden shingles, as the surface is rotted by dirt and algae.
