Moss, algae, and roof debris can cause serious damage to your home or building, trapping moisture, lifting shingles, and shortening the life of your roof. Left untreated, they can lead to leaks, rot, and costly repairs. Our professional roof cleaning and de-mossing service removes growth safely and helps rainwater shed properly, protecting your property and roof investment.

At Harrison, we remove moss by hand and use low-pressure, roof-safe methods. We apply a roof-approved de-mossing treatment to stop regrowth, lightly rinse where needed, and clear valleys, gutters, and downspouts for proper drainage. The treatment we use clears green and black algae, mildew, fungus and lichen as well as moss. It is eco-friendly and breaks down naturally, and it will not corrode or burn your roof — nothing acidic, nothing harsh.
Keeping the roof itself intact matters to us as much as getting it clean. We protect your property with ladder stabilizers and safety gear—and we tidy up all debris before we leave.
We deliver roof cleaning, moss removal, and de-mossing across residential, commercial, and industrial properties at any scale. Whether it’s a family home, a strata high-rise, or an industrial plant, our trained technicians have the right tools and safety gear for the job.
