Professional Roof Cleaning in Surrey That Protects and Lasts
Your roof is your home’s first line of defence against the British weather, yet it’s also one of the most neglected parts of a property. Over time, moss, algae, and lichen can take hold, silently damaging tiles, blocking gutters, and eroding the mortar beneath. That’s where Davey & Sons comes in. As specialists in professional roof cleaning in Surrey, we restore roofs to their best condition using safe, proven techniques that won’t harm your tiles. Whether you’ve noticed green patches spreading across the slopes or you’re preparing your home for sale, our roof cleaning in Surrey service delivers results that last.
What Does Our Roof Cleaning Include?
We hand-clear all visible moss, lichen, and debris from your roof surface before any treatment begins, ensuring chemicals reach the tile directly.
A professional roof biocide treatment is applied across the entire roof. This kills any remaining spores at root level, preventing regrowth for years to come.
Once cleaned, your tiles are inspected for cracks, slippage, or mortar deterioration. We'll flag any issues found and advise on next steps.
Where appropriate, a low-pressure soft wash rinse is used to remove residue without any risk of tile damage.
Our Soft Wash Method — No Pressure Washing
You may have seen other companies offer high-pressure jet washing for roofs. We don’t. Here’s why: pressure washing forces water deep under tiles, blasts away protective coatings, and can loosen or crack aged clay and concrete tiles. The results might look good for a month, but the damage done lasts much longer.
Our soft wash roof cleaning Surrey approach is different. We use low-pressure application, no more than a garden hose, combined with a professional-grade roof biocide treatment that does the heavy lifting. The biocide penetrates moss and algae at the root, breaking down organic growth over several weeks. By the time the treatment has run its course, the remaining debris simply washes away in the rain.
This method is safer for your tiles, safer for your gutters, and, because it kills the source rather than just washing the surface, it keeps your roof cleaner for significantly longer.

Roof Cleaning FAQs
Yes, and it's one of the most common questions our customers ask. Moss acts like a sponge, trapping water against the surface of your tiles. Over time, this leads to freeze-thaw damage in winter, erosion of the tile surface, and weakening of the mortar joints. If you're wondering "does moss damage roof tiles?", the short answer is: if left unchecked, it absolutely can. Early treatment through roof moss removal Surrey is always more cost-effective than repairs down the line.
Our roof biocide treatment typically keeps moss and algae at bay for three to five years, depending on the roof's exposure and the surrounding environment. Properties with significant tree coverage or north-facing slopes may need retreatment slightly sooner. We'll always advise you on expected longevity when we provide your quote.
When carried out correctly, yes, absolutely. Our soft wash roof cleaning Surrey method uses low-pressure application and specialist biocide solutions rather than high-pressure jet washing, which can crack, dislodge, or strip the surface of tiles. Our approach is gentle on the roof structure and just as effective, often more so, as it targets the root of organic growth rather than just blasting the surface.
Most homeowners in Surrey benefit from roof tile cleaning Surrey every three to five years. However, the right frequency for your roof will depend on factors like tree coverage, the age and type of your tiles, and local weather patterns. After your first treatment, we'll give you honest, tailored advice on when to book your next clean — and we won't push for unnecessary repeat visits.
