Why does your roof need cleaning?
Moss and algae on roof tiles are not just an eyesore. Moss holds moisture against the tile surface, which accelerates weathering and can lead to cracking during freeze-thaw cycles. On the Isle of Wight, the damp maritime climate means moss and lichen growth is a constant problem, especially on north-facing roofs.
A clean roof improves kerb appeal dramatically. Most people do not realise how much moss has accumulated until they see the before and after photos. It also helps the tiles last longer and prevents moss from blocking gutters and downpipes.
What roof types do we clean?
- Concrete roof tiles
- Clay roof tiles
- Slate roofs
- Flat roofs (careful low-pressure wash)
- Ridge tiles and hip tiles
Our roof cleaning process
We use a combination of manual scraping for heavy moss build-up and controlled pressure washing to remove embedded growth. We work from the ridge down, washing debris into the gutters which we then clear. For delicate tiles, we use a soft wash system where the cleaning agent does the work and we rinse at low pressure.
We take care around flashings, vents, and any fragile areas. All debris is cleared from gutters and downpipes after the clean so you are not left with blocked drainage.
How much does roof cleaning cost?
Roof cleaning on the Isle of Wight varies depending on roof size, pitch, and the level of moss build-up. Typical costs range from £400 to £800 for a standard three-bedroom house. We always provide a free quote after assessing the roof.
Manual Moss Removal
Heavy moss scraped by hand before washing to avoid forcing debris under tiles.
Controlled Pressure
Adjusted PSI for each tile type. Slate and clay get lower pressure than concrete.
Gutter Clear Included
All debris cleared from gutters and downpipes after the roof is cleaned.
Biocide Treatment
Optional after-treatment that prevents moss and algae regrowth for up to 12 months.
