Clean the roof, repoint it, then coat it

Concrete tiles go porous and green long before they go bad. We wash the roof down, clear the moss out of the gutters, repoint ridges and verges, then roll on two coats of breathable coating in the colour you pick.

Tired-looking roof but no leaks? This is usually the cheaper answer. Ask for a survey.

What the job involves

Four stages, none of them skipped

Full moss removal and wash down, gutters cleared after

Broken and cracked tiles swapped out before coating

Ridges and verges repointed where the mortar has gone

Two coats of breathable coating, brush finished at the edges

Gutters and driveway cleaned down when we finish

The coating has to breathe. Sealing a concrete tile roof with the wrong product traps moisture and does more harm than good.

Concrete tile roof after cleaning and coating
When it is worth doing

And when it is not

Worth it: sound concrete tiles that have gone green and porous

Worth it: you want the house to look right before selling

Not worth it: tiles are delaminating or crumbling at the edges

Not worth it: the felt underneath has failed, which needs a re-roof

We will tell you honestly which of those your roof is. Coating a roof that needs replacing just delays the bill.

Questions

Roof painting questions we get asked

How long does roof coating last?

On a properly cleaned and repointed concrete tile roof, expect eight to twelve years before the colour starts to fade. It is a cosmetic and protective treatment, not a substitute for a covering that has reached the end of its life.

Does roof painting stop leaks?

No. If water is getting in, something is broken and painting over it will not fix it. We repair the cause first, or tell you the roof needs replacing, and only then talk about coating.

Will power washing damage my roof tiles?

Not if the pressure is right and the operator knows what they are doing. Old, soft or delaminating tiles can be damaged, which is why we check the condition first and swap out anything fragile before washing.

Can you paint a slate roof?

We do not recommend it. Natural slate does not need coating and paint sits on the surface and flakes. Slate roofs that look tired usually need repointing of the ridge and a clean, not paint.
