Professional Roof Cleaning Across Wales & South West England

Restore the appearance, safety and lifespan of your roof with professional roof moss removal and cleaning services. We use safe, non-abrasive methods designed to protect roofing materials while giving your property a clean, well-maintained finish.

Why Roof Cleaning Matters

Over time, moss, algae, and organic growth build up on roof surfaces. This not only affects the appearance of a property, but can also cause practical issues if left untreated.

Moss retains moisture, which can lead to tiles remaining damp for long periods. During colder months, this increases the risk of frost damage, cracking, and displacement. As moss breaks away, it can also block gutters and downpipes, leading to overflow, damp problems, and unnecessary strain on the drainage system.

Regular roof cleaning helps protect the roof covering, improves water run-off, and reduces long-term wear. It also restores the overall appearance of the property, often making a significant visual improvement without the need for costly repairs or replacement.

How Mossy Roofs Attract Wildlife (and Impact Solar Panels)

Moss-covered roofs can create ideal conditions for unwanted wildlife. The retained moisture and organic material provide shelter and nesting opportunities for birds, as well as insects that birds feed on. Over time, this can lead to birds lifting or dislodging tiles to gain access to roof spaces.

Once established, nesting activity can cause damage to roof coverings, underfelt, and insulation. Bird droppings and nesting debris can also block gutters and drainage points, increasing the risk of water ingress and damp issues. Regular roof cleaning helps reduce these conditions, making the roof less attractive to wildlife and lowering the risk of further damage.

Our Roof Cleaning Methods

Manual Moss Removal (Non-Abrasive)

We gently scrape and remove moss using telescopic poles and specialist tools that protect tile integrity and prevent breakage.

Soft-Wash / Pure Water Rinse

After removal, we apply a controlled low-pressure rinse to clear dust, debris and remaining organic fragments — without the risks of pressure washing.

Professional Biocide Treatment

We apply a roof-safe biocide that kills microscopic roots and spores, preventing regrowth for 12–36 months and restoring a clean finish over time.

Optional Roof Sealant / Protective Coating

For long-lasting protection, we can apply a professional-grade roof sealant after cleaning.
This clear or tinted coating:

  • Creates a water-repellent barrier

  • Helps prevent future moss, algae and lichen growth

  • Protects tiles from moisture absorption

  • Enhances overall roof appearance

  • Extends the life of your roof between cleans

Our sealants are breathable, UV-stable, and designed for use on concrete, clay and slate tiles without altering roof ventilation or causing moisture trapping.
