Professional Roof Cleaning

Your roof is constantly exposed to the elements, making it particularly vulnerable to moss, algae, and lichen growth. Over time, these organic materials trap moisture against roof tiles, accelerating deterioration and potentially leading to costly leaks and structural damage. Professional roof cleaning not only restores your property's appearance but actively extends the lifespan of your roof, protecting one of your most valuable investments.

Two ways we clean a roof

Not every roof needs the same treatment, so we quote for two distinct services. Tell us which one you are after when you request a quote, or ask us to recommend one after we have assessed the roof.

Roof moss removal and biocide wash

Our standard roof clean. We scrape and brush the moss, lichen and algae off the tiles, clear the debris from valleys, hips and gutters, then apply a professional-grade biocide that kills the remaining spores at the root and keeps working for months afterwards. Because it is a soft wash, there is no high-pressure water hitting your tiles. This is the right choice for most pitched tile and slate roofs, and it carries our 5-year biocide guarantee.

Roof steam cleaning

Roof steam cleaning uses low-pressure, high-temperature steam (DOFF and similar systems) to lift ingrained dirt, algae staining and heavy organic growth without blasting the surface. It is the method we recommend for older or more delicate roofs, listed and heritage properties, and roofs where the staining has gone beyond what brushing and biocide alone will shift. Steam cleaning is usually finished with a biocide treatment as well, so the roof stays clean for longer.

Not sure which one your roof needs? Send us a photo or book a free assessment and we will tell you honestly, including when a straightforward moss removal and biocide wash is all that is required.

Specialist Equipment and Methods

We employ a combination of proven techniques tailored to your specific roof type and condition. Our soft-washing system uses carefully controlled water pressure combined with professional biocide treatments to safely remove moss and algae without damaging delicate roof tiles. For heavily soiled roofs, we use specialist brushing equipment that gently removes organic growth whilst preserving the integrity of the tiles. All work is carried out by trained operatives using appropriate access equipment and full safety measures.

Our Comprehensive Process

Every roof cleaning project begins with a thorough inspection to identify any damaged or loose tiles that require attention before cleaning commences. We then apply a professional-grade biocide treatment that kills moss and algae at the root. The cleaning process removes all visible growth, debris, and organic matter, with particular attention paid to valleys, hips, and areas around chimneys where growth tends to be heaviest. Finally, we apply a protective biocide coating that continues working for months after the initial clean, preventing rapid regrowth and keeping your roof cleaner for longer.

Long-Term Benefits

Regular professional roof cleaning delivers substantial benefits beyond aesthetics. Clean roofs allow proper water runoff, reducing the risk of leaks and water ingress. Removing moss prevents tile lifting during high winds and stops organic matter from blocking valleys and gutters. The enhanced kerb appeal from a clean roof is immediately noticeable and particularly valuable when marketing your property. Many insurance policies also require evidence of proper roof maintenance, making professional cleaning a wise investment.

Safety and Professional Standards

Roof work is inherently dangerous and should never be attempted without proper training and equipment. Our fully insured team holds all necessary health and safety certifications and uses professional access equipment including scaffolding, roof ladders, and harness systems. We protect your property throughout the cleaning process, ensuring gardens, patios, and adjacent areas are shielded from debris and cleaning solutions. Every job is completed to the highest industry standards with full public liability insurance for your peace of mind.
