Is Your Roof Suitable for Coating?
Roof coating works best on structurally sound tiles that have become porous, tired-looking, or moss-prone. Here's how to tell if your roof is a good candidate:
✅ Good Candidates for Coating
- Concrete or clay tiles that are intact but porous
- Tiles absorbing water or showing dark damp patches
- Moss and algae keeps returning after cleaning
- Roof looks old and tired but has no structural damage
- You want to change the colour or refresh the appearance
- Roof has minor cracked pointing or ridge tiles (we repair these first)
❌ When Replacement May Be Better
- More than 30% of tiles are cracked or broken
- Roof timbers or sarking board are damaged
- Property is undergoing major structural renovation
- Listed building with specific material requirements
- Roof is more than 40 years old with multiple failed repairs

Our 4-Step Roof Coating Process
Free Roof Survey
Our specialist visits your property, inspects tiles from ground level and via ladder, and assesses suitability. You receive an honest recommendation — and a written quote with no pressure to proceed.
Full Clean & Treatment
Every coating job starts with a thorough clean. We remove all moss, algae, lichens, and debris using professional pressure washing and biocide treatment. This step is critical — coating over dirt or growth causes failure within 2–3 years.
Repairs First
Before any coating is applied, we repair cracked or slipped tiles, re-bed or re-point ridge tiles, check flashings, and seal any vulnerable areas. You're getting a repaired and protected roof — not just a painted one.
Multi-Coat Application
We apply a minimum two-coat system using professional-grade products selected for your tile type. Each coat is allowed to cure fully before the next application. The result is a seamless, sealed surface that stops water absorption and resists frost, UV, and biological growth.
Roof Coating Types We Use
We select the right coating for your tile type, roof condition, and budget. Here's what each system offers:
Acrylic Roof Coating
From £40/m²
Best for: Sound tiles with mild porosity and minor weathering
Lifespan: 10–12 years
- Water-resistant barrier prevents damp absorption
- Inhibits moss and algae growth
- Available in a range of colours
- Most affordable option
Ideal for: 2–3 bed terraced or semi-detached homes where budget is a priority
Polyurethane Roof Coating
From £50/m²
Best for: Roofs with higher porosity or mixed tile types
Lifespan: 12–15 years
- Higher elasticity handles freeze/thaw cycles (critical in Scotland)
- Better adhesion on rough or textured tiles
- More durable than acrylic in wet climates
- Mid-range cost with premium performance
Ideal for: Most Scottish homes — handles the climate well
Silicone Roof Coating
From £60/m²
Best for: Maximum waterproofing, premium long-term protection
Lifespan: 15+ years
- Breathable membrane prevents trapped moisture
- Unmatched water repellency
- UV-resistant, won't fade or chalk
- Longest lifespan of all coating types
Ideal for: Exposed properties, homes in high-rainfall areas, or where maximum protection is needed
Why Scottish Homes Benefit Most from Roof Coating
Scotland's climate is particularly hard on concrete roof tiles. The combination of high rainfall, freeze-thaw cycles, and persistent moss growth accelerates tile porosity faster than in southern England. Once tiles become porous, water soaks in — and when that water freezes, it expands inside the tile, causing spalling and structural damage.
Stops Water Absorption
Porous tiles can absorb up to 20% of their own weight in water. A sealed tile absorbs almost none. This single factor prevents the majority of frost damage common in Scottish winters.
Ends the Moss Cycle
Moss returns every 2–3 years on untreated roofs. Cleaning alone doesn't prevent regrowth — the porous surface invites it back. A sealed surface gives moss nowhere to grip.
Avoids Replacement Cost
A full roof replacement disrupts your home for 5–7 days, costs £6,000–£12,000, and generates significant waste. Coating achieves similar protection in 1–2 days at a fraction of the cost.
