You have probably noticed your roof looking greener and darker year after year, especially on the north-facing side that gets less sun. Algae and atmospheric grime do not just look bad — they hold moisture against the tiles, which speeds up frost damage in winter and shortens the life of the roof. You may have thought about hiring a pressure washer and doing it yourself, but high pressure can blast the protective coating off the tiles and do more harm than good. We can clean it safely and restore the original look without damaging the surface.
When You Need Roof Cleaning
You need roof cleaning when you can see a green or dark film across the tiles, especially on north-facing slopes that stay damp for longer. Black streaks running down from the ridge are algae growth, and a heavy green coating usually means moss is starting to take hold too. The damp South East England climate means algae grows fast on roofs across Buckinghamshire, Surrey and Hampshire, particularly in shaded or tree-lined areas where the roof never fully dries out. Waiting means the staining gets deeper, the tiles absorb more moisture, and the frost damage cycle speeds up — every freeze-thaw cycle cracks the tile surface a little more, and over a few winters the tiles start to spall and fail. A clean now extends the life of the roof and improves the appearance of the whole property. It also clears the debris that would otherwise wash into your gutters and cause blockages, so it protects your guttering as well as your roof.
Our Roof Cleaning Process
We use gentle, low-pressure cleaning methods that remove algae, moss and staining without blasting the protective coating off the tiles — high pressure can do more harm than good, stripping the surface and shortening the life of the roof. We start by clearing loose moss and debris by hand, working from the ridge down so everything falls clear of the tiles. We then treat the surface with a biocidal wash that kills the algae at the root, rather than just removing the visible growth, which slows regrowth significantly. Finally, we rinse at the correct low pressure to lift the staining without damaging the tile surface. We clear the gutters as part of the job, because everything we remove from the roof ends up in them, and a blocked gutter would cause more damage than the algae we just removed. Most roof cleaning is done in a single day, with no mess left behind.
Roof Cleaning Cost in Iver
The cost depends on the size and pitch of the roof, the severity of the algae and staining, and whether moss removal is needed as well. A heavily moss-covered roof takes longer to clean than one with light algae growth.
