“Was quoted a full re-roof by another company. Select Roofing came out, said the tiles were actually fine and coating would sort it. Saved us thousands and the roof looks brand new.”

Roof Coatings & Renovation — Merseyside
Not Every Tired Roof Needs Replacing
Concrete and clay tiles become porous over time — the surface breaks down, moss and algae take hold more easily, and the roof looks tired even when the underlying structure and tiles are still sound. A full replacement isn’t always necessary to fix this.
Roof coating and renovation cleans the existing tiles thoroughly and applies a specialist waterproof coating, restoring appearance and improving weather resistance at a fraction of the cost of a new roof.
We’ll tell you honestly whether your roof is a genuine candidate for this — it works well on structurally sound roofs that are simply tired and porous, but it isn’t the right answer for a roof with underlying tile, felt or structural problems. Coating a roof that actually needs repair just delays a more expensive job later.
📞 Call for a free surveyHonest suitability check first
We assess whether coating is genuinely right for your roof before recommending it — not a default upsell on every job.
Full clean before coating
Tiles are properly cleaned of moss, algae and debris before any coating is applied, not just coated over existing buildup.
Improved weather resistance
A specialist coating reduces porosity, helping tiles shed water more effectively and slowing future moss and algae regrowth.
Significant cost saving
Genuinely a fraction of the cost of full replacement, when your roof is a suitable candidate.
⚠ When Coating Isn’t the Right Answer
If your roof has cracked or slipped tiles, failed felt underneath, or structural issues, coating won’t fix any of that — it will just sit on top of an unresolved problem. We check for this during survey and will tell you plainly if your roof needs repair or replacement instead, even though coating is the cheaper job for us to sell.
What's involved
How Roof Coating & Renovation Works
1. Suitability survey
We inspect your roof properly first — tiles, felt, structure — to confirm coating is genuinely appropriate before quoting.
2. Full clean
Moss, algae, lichen and general debris are thoroughly removed — see our moss removal guide for how this is done properly.
3. Repairs first, if needed
Any minor repairs identified are addressed before coating, not after — coating over an unresolved issue just hides it temporarily.
4. Coating application
A specialist waterproof coating is applied, restoring appearance and improving water shedding across the whole roof surface.
Common questions
Roof Coatings & Renovation — What People Ask
How do I know if my roof is a good candidate for coating rather than replacement?
The key question is whether the underlying tiles, felt and structure are sound. If the roof is simply tired, porous or covered in moss and algae but structurally fine, coating is often a genuine option. If there's cracking, slippage or structural movement, coating isn't the right answer. We check this at survey, honestly.
How long does a roof coating last?
Typically several years of improved weather resistance and appearance, though this varies with tile type, exposure and the specific coating used. We'll give you a realistic expectation at survey stage rather than an inflated one.
Is roof coating cheaper than a new roof?
Yes, significantly, when your roof is a genuine candidate. It's not a substitute for replacement on a roof that actually needs it, but for a structurally sound, tired-looking roof, it's a real cost-effective option.
Does coating stop moss coming back?
It genuinely slows regrowth by reducing surface porosity, but it doesn't eliminate the conditions that caused moss in the first place, such as shade or dampness. Periodic maintenance is still worthwhile.
