Commercial building, tiles in good condition
Case-by-case survey
Coating is possible. An expert first checks that it is worth it.
CONCRETE TILE ROOF COATING
Reflective coating on concrete tiles: possible, after a survey
Our coatings are built for commercial roofs: steel deck, bitumen membrane, EPDM and PVC. They can go on tiles, but we don't recommend it.

What to know
Concrete tiles are a special case.
They store heat
Concrete tile soaks up the sun and releases the heat into the attic and the top floors.
They turn porous
Over the years, concrete tile weathers, turns porous and grows moss.
Outside our core substrates
Our coatings are built for steel deck, bitumen membrane, EPDM and PVC. Tile isn't one of them.
Before any coating goes on, an expert checks whether it makes sense for your building.
Our system
A system formulated for steel deck and membranes.
The Covalba system pairs a bonding primer, a reflective resin and, depending on the range, a protective topcoat. On concrete tiles, an expert first checks the condition of the roof and whether a coating is really worth it.
Before any work on tiles
- Survey of tile condition, roof pitch and building use
- A clear, reasoned opinion on whether to coat
- If the project goes ahead: cleaning and moss treatment
Our core substrates
Coatings built for commercial roofs.
Our systems are formulated for these four substrates, the most common on industrial and commercial buildings.
Steel deck
On sound sheeting, CovaTherm goes on after prep. If the steel is rusting, CovaMetal 20 takes over.
Bitumen membrane
The substrate on 80% of the roofs we treat, flat or low-pitch.
EPDM
Rubber membrane on flat roofs, coated after surface prep.
PVC membrane
Synthetic membrane in good condition, with an adhesion test first.
Case by case
What we advise, depending on your situation.
On concrete tiles, we don't offer a standard package. Here is how we handle requests.
Site with other roof types
Treat the steel deck or membranes first
Those are the substrates our products are built for.
Broken, porous or mossy tiles
Repair by a roofer first
A coating won't restore a damaged roof.
Private house
Outside our scope
Covalba works for businesses only.
Does your site have other roofs?
Steel deck, bitumen membrane, EPDM or PVC: those are our core substrates. We can assess your whole site.
Where we step in
On tiles, a survey comes first.
Concrete tile is porous and often covered in moss. If the survey confirms a coating is worth it, the roof is cleaned and the moss treated before application. If another option suits your building better, we tell you from the start.

FAQ
Your questions, our answers.
Yes, it’s possible, but we don’t recommend it. Our coatings are built for commercial roofs: steel deck, bitumen membrane, EPDM and PVC. An expert reviews each request case by case.
Same answer: it can be done, but it isn’t what we recommend. We’ll discuss it when we assess your roof.
It works on summer heat. It doesn’t replace insulation, which is about winter comfort.
No. Covalba works for businesses only: industrial, commercial, office and public buildings.
Have your roof assessed by an expert.
Tell us about your building and the state of the tiles. We'll tell you whether a coating makes sense, or which roof to treat first.

Tout comprendre sur le sujet.
Concrete tile covers a lot of pitched roofs. It stores heat and weathers over time. A reflective coating can go on it, but our products are built for other substrates: steel deck, bitumen membrane, EPDM and PVC.
Why a concrete tile roof runs hot
Concrete tile is dense. It banks the sun all day and slowly bleeds it back down into the rooms below.
Can you coat concrete tiles?
Yes, once the roof is cleaned and the moss treated. Covalba still doesn’t recommend it: its systems are formulated for commercial roofs, and every tile request goes through a survey.
The roofs our products are built for
Steel deck, bitumen membrane, EPDM and PVC: these are the substrates Covalba works on every day, on industrial, commercial and office buildings.
Getting your roof assessed
A Covalba expert looks at the condition of the roof, its pitch and how the building is used before giving an opinion. The survey comes with no commitment.
