Are Roof Coatings Worth It?

Quality breathable roof coatings can genuinely restore tile colour and extend life when applied to suitable substrates after proper cleaning. Non-breathable coatings, spray-applied without preparation, are one of the highest-complaint categories in the UK roofing sector.

When coatings make sense

Aged concrete tiles with intact structure but eroded surface coating are legitimate candidates. So are some clay tiles where cosmetic uniformity matters. In those cases a properly prepared, breathable, UV-stable coating restores appearance and adds a decade of usable life.

When coatings are a red flag

Cold-called quotes offering 'lifetime' coatings on any roof, non-breathable acrylics that trap moisture under the film, and coatings applied without prior cleaning are all warning signs. The industry has a genuine rogue-trader problem in this space — be sceptical.

Questions to ask before agreeing to a coating

Any legitimate coating quote should answer these questions in writing:

• What product exactly is being applied — brand and reference?
• Is it breathable (vapour-permeable)?
• What surface preparation is included?
• What manufacturer warranty applies, and to whom?
• Can I see previous jobs from at least 5 years ago?

Our approach

We recommend coatings selectively — typically on aged concrete tile after a full clean where the customer specifically wants uniform colour restoration. On slate, clay, and any roof under 20 years old, we normally advise against coating.
