How We Work

Our Roof Cleaning Process

At Roof Cleaning Winchester, we believe the safest and most effective way to clean a roof is through careful, hands-on methods carried out by a qualified roofer. Our process is designed to protect your roof while delivering long-lasting results.

Roof Inspection & Assessment

Every roof cleaning begins with a thorough visual inspection. As a qualified roofer, I assess the condition of the tiles, ridges, and fixings before work starts. This ensures your roof is suitable for cleaning and allows any existing issues to be identified early.

Manual Moss Removal

All roof cleaning is carried out using manual moss removal only. Moss and debris are carefully removed using specialist roof scrapers and telescopic poles, giving full control over the process and avoiding unnecessary stress on the tiles. This method eliminates the risks associated with pressure washing.

Gutter & Debris Clearance

During the cleaning process, all removed moss and debris are safely collected and cleared away. Gutters and downpipes are checked to ensure rainwater can flow freely once the roof is clean.

Residual Biocide Treatment

Once manual cleaning is complete, a professional residual biocide treatment is applied to the roof. This treatment targets remaining algae, lichen, and moss spores that are not visible to the eye. It continues working over time, helping to prevent regrowth and maintain a cleaner roof for longer.

1-Year Moss-Free Guarantee

To give you complete peace of mind, all roof cleaning work comes with a 1-year moss-free guarantee. Thanks to our careful manual removal process and residual biocide treatment, your roof is protected against moss regrowth for 12 months following treatment.

Long-Lasting Results & Aftercare

After treatment, natural weathering gradually removes any remaining staining, improving the roof’s appearance over time. The result is a clean, well-maintained roof that’s protected and built to last.
