Natural Slate Roof Cleaning in St Merryn, Cornwall
Gentle Cleaning for Long-Lasting Results – Trusted by Local Contractors
At Atlantic Clean, we were recently commissioned by a local construction contractor in St Merryn, a beautiful village just outside Newquay, Cornwall, to carry out a professional roof clean on a natural slate property. The goal: remove stubborn lichen, algae, and biological build-up while preserving the integrity and appearance of the roof tiles.
This wasn’t just about looks – it was about protection, preservation, and long-term performance.
🌿 The Problem: Algae and Lichen Growth on Slate Roofs
Natural slate roofs are a popular choice in Cornwall due to their traditional look and durability. However, over time, moss, algae, and lichen thrive in our damp, sea-swept climate – particularly in shaded or north-facing areas.
Left untreated, these organic growths can:
-
Hold moisture against the slate
-
Accelerate wear and discolouration
-
Create slip hazards on lower-level roofs
-
Reduce kerb appeal and property value
That’s why regular maintenance is so important – especially in coastal communities like St Merryn, Trevone, Padstow, and Porthcothan.
🧼 Our Cleaning Approach: Low Pressure, Maximum Care
We never use harsh high-pressure washing systems on slate roofs, as they can crack or weaken tiles. Instead, our team used a low-pressure wash system, specifically designed for heritage materials like natural slate.
This gentle method:
-
Removes visible algae, dirt, and debris
-
Protects the integrity of the slate tiles
-
Ensures no dislodging of fixings or pointing
After the clean, we applied an HSE-approved biocide treatment. This post-cleaning solution is essential for long-lasting results – it works with nature by killing any remaining spores and preventing regrowth over time.
✅ Why Use HSE-Approved Biocide?
Unlike bleach-based treatments or DIY methods, our biocide is:
-
Certified safe for the environment and surrounding vegetation
-
Approved by the Health and Safety Executive (HSE)
-
Non-corrosive to roofing materials
-
Long-lasting, continuing to protect the roof surface for 12-18 months
This treatment is especially effective in coastal areas like St Merryn, where the climate is perfect for moss and lichen to return quickly.
🧰 Trusted by Construction Professionals
This project was carried out in partnership with a respected local building contractor who trusted us to prepare the roof surface following construction works. Our team coordinated effectively with their project schedule to ensure minimal disruption and a high-standard finish that matched the rest of the property development.
“John and the team at Atlantic Clean were professional, efficient, and the results speak for themselves. The roof looks incredible, and the biocide treatment gave us peace of mind. We’ll definitely be using them again.” – Local Contractor, St Merryn
