Recent Roof Cleaning
Projects

Every roof we clean is different — different property, different tile type, different growing conditions, different degree of accumulation. These are some of the most recent projects we have completed. Each one is documented with before and after photography, a written treatment record and full DDAC biocide protection applied as standard.

How every project works

The Same Five Stages on Every Project

Whether the property is a semi-detached in Beaconsfield or a large executive home in Virginia Water, the process is identical. What changes is the time it takes — not the standard.

1

Free survey

We assess the roof in person before providing a quote — tile type, moss density, mortar condition, structural concerns. Drone where suitable.

2

Manual removal

All moss removed by hand using the carbon fibre pole system. Methodical. Section by section. No high-pressure water on the tile surface.

3

Low-pressure rinse

Controlled rinse to clear fine residue and prepare the tile surface for biocide treatment. Calibrated to the tile type throughout.

4

Biocide treatment

Professional DDAC biocide applied to the full treated surface. Inhibits regrowth for 2–4 years. Not a domestic product.

Why homeowners choose Glanville

What Sets These Projects Apart

The pattern across every case study on this page is the same: a homeowner who chose a specialist, received a proper survey, had the work done correctly, and has a documented result to show for it.

Biocide included every time

Every project on this page included professional DDAC biocide treatment as a standard element of the service — not an optional add-on. This is the single biggest factor in how long the results last.

Safe method for every tile type

The carbon pole system used on every project does not apply pressurised water to the tile surface. It is safe for clay, slate, reclaimed and concrete tiles — confirmed by survey before work begins.

Documented on every project

Every project receives before and after photography, a written treatment record confirming product and date, COSHH documentation and a homeowner aftercare guide. Standard. Not optional.

Survey before the price

Every project on this page was quoted after a free, in-person survey of the specific roof — not by phone, not from photos. A fixed price based on what we found when we looked.

12-month treatment support

Every project comes with 12-month treatment support. If any early regrowth appears within the first twelve months, we return to assess and advise at no charge.

40+ verified five-star reviews

Our Google reviews reflect the standard of the work on these pages. The recurring themes — thoroughness, honest communication, documented results — are the same on every job.

Does Your Property Need the Same Care?

If your roof has visible moss, hasn’t been professionally treated in the last few years, or was cleaned previously without biocide treatment, the right first step is a free survey. We assess your roof in person, explain exactly what we find and what we recommend, and provide a clear, fixed written quote with no obligation to proceed.
