Why act
Dark concrete tiles, hot rooms below.
They store heat
Concrete tiles soak up the sun and radiate it down into the attic and the floors below.
They turn porous
Over the years, concrete tiles weather, go porous and grow moss.
The rooms below cop it
Under an exposed roof, the attic and the top floors get hard to use in summer.
A reflective roof coating treats the tiles and cools them down — no major work.
The CovaTherm solution
Your tiles reflect the sun instead of storing it.
On a concrete tile roof, the CovaTherm reflective coating goes on porous substrates. It bounces the sun back, drops the temperature in the rooms below, and protects the tiles — no tile removal.
The system
- Clean and treat the moss
- CovaTherm reflective coating
- Solar lacquer on glazed openings if needed
What you gain
Cooler rooms below, a protected roof.
Up to 8 to 10°C cooler under the roof, from the first summer.
Cooler rooms below
The tiles stop radiating their heat, so the rooms below are comfortable again come summer.
Protected tiles
The coating guards the tiles against moisture, moss and UV.
A fresh look
The roof gets a clean, even finish — no tile replacement.
No major work
Applied from the ground, with no tile removal and no major job.
The smart investment
Cool the rooms below without redoing the roof.
As long as the tiles are sound, a reflective roof coating takes the heat out and protects the covering — no major work.
Porous tiles, moss
Clean and treat, then CovaTherm
Brings back the look and protects, with no tile removal.
Broken tiles
Swap them out, then coat the whole roof
Fix the spot issues first, then protect the rest.
Rooms below needing a deep renovation
Weigh it against insulation if winter comfort is also at stake
A reflective coating handles summer heat, not insulation.
Cool the rooms below without swapping the tiles.
Tell us about your roof's porosity, moss and any broken tiles. We'll help you spec the right coating to protect the covering and take the heat out.
What it works on
Built for concrete tile, a porous substrate.
Concrete tile is porous and needs careful prep: we assess the covering, treat the moss and lichen, and clean the surface before the reflective coating goes on.

FAQ
Your questions, our answers.
Cooler rooms below without major work.
CovaTherm reflects the sun, protects concrete tiles and improves summer comfort without removing the covering.
Fast technical replyNo tile removalNo commitment
Tout comprendre sur le sujet.
Concrete tile covers a lot of pitched roofs on commercial, public and residential buildings. It stores heat and weathers over time.
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.
How a reflective roof coating works on concrete tiles
A reflective coating bounces the sun back instead of storing it. CovaTherm grips porous substrates once they are cleaned and the moss is treated.
Reflective tile roof coating or a full renovation
As long as the tiles are sound, a reflective coating at €20-25/m² protects the covering and cools the rooms below for a fraction of the cost.
A principle backed by research
By lifting solar reflectance (and SRI), a reflective surface sends back the radiation dark tiles would soak up, cutting the heat that reaches the rooms below.
Protection that lasts
The CovaTherm system is built to last 8 to 10 years while protecting the tiles.
