Will the work disrupt activity in my offices?

No. Everything is done from the outside. Your teams keep working, and the operation is organized so as not to disturb floor occupancy.

What does it do for employee comfort?

By dropping the temperature under the roof, a reflective coating makes the floors, especially the top ones, far more bearable in summer.

Does a reflective roof really cut my energy costs?

Yes. By easing the load on air conditioning, it lowers the building’s consumption and delivers lasting savings on operating costs.

Does the coating also protect my roof?

Yes. The coating protects the waterproofing from UV and heat, which extends the roof’s service life.

Is it useful if my offices are not air-conditioned?

Yes. Without air conditioning, the benefit is measured in comfort: the roof transmits less heat during heat waves.

Which types of roofs are compatible?

Steel deck, bitumen, membranes and concrete, including older roofs after a technical assessment.

And in winter, will I lose on heating?

The winter effect is limited: the sun is low and mainly heats the facades. The summer gain largely makes up for it.

How long does the effectiveness last?

Covalba coatings retain their reflectivity for 8 to 10 years, well beyond low-end products.

Why act

The heat is wearing down your teams.

Top floors overheat, air conditioning runs hard, and working conditions deteriorate during summer peaks.

Employees suffering in the heat

Above 28-30°C, comfort, concentration and well-being drop.

Unlivable floors under the roof

Top floors become hard to occupy during summer peaks.

Air conditioning under pressure

Units run at full capacity to hold the setpoint.

Rising energy costs

Across large surfaces, the cooling bill weighs heavily every summer.

All these problems share a common cause: a roof that absorbs heat instead of reflecting it.

The Covalba solution

Your roof reflects instead of heating up.

A reflective roof coating goes after the cause: a light-colored surface bounces the sun back before it reaches the offices.

Conventional roof — up to 80°C at the surface

Dark surface
Absorbs heat
Strains air conditioning

Reflective roof — up to 90% of the sun reflected

Light-colored surface
Stays cooler
Cuts the heat load

Passive solution, with no energy consumption
Applied from the outside, without interrupting activity
Compatible with steel deck, bitumen and membrane
Durable: 8 to 10 years of service life

For a commercial building, this work also strengthens the value of your asset.

Durability

The cheapest option ends up costing more on a large building portfolio.

Across several thousand square meters, durability matters as much as the price per square meter.

Estimate my savings

Covalba helps you quantify the expected savings on your building.

Measurable benefits

Cool teams, controlled costs, a more valuable building.

A reflective roof coating works on three things at once: workplace comfort, the cooling bill and energy performance.

-8 to -10°C

under your roof

From the very first summer

More comfortable employees

A cooler, more comfortable environment supports focus and well-being.

Less strain on air conditioning

Less transmitted heat, up to -20% on the cooling bill.

Strengthened asset value

A passive action that improves the building's energy performance.

Protected roof

The coating protects the waterproofing from UV and heat.

CSR and employer brand

A visible action for quality of life at work.

Each type of commercial building has its own specifics.

Your buildings

A solution for every commercial building.

Headquarters, office floors, open-plan spaces and showrooms do not experience heat the same way.

Headquarters

Large roofs above continuously occupied floors.

Office buildings

Top floors overheating under the roof.

Open-plan spaces

High occupant density and sensitivity to thermal comfort.

Reception spaces

Comfort for teams, visitors and clients.

Mixed-use buildings

Treatment at the scale of a commercial site.

That leaves one question: how the work unfolds on a site that stays occupied.

The process

4 steps. Offices stay occupied.

Your teams keep working. The work is carried out from the outside by your professional contractor and is organized around the occupancy of the floors.

Tout comprendre sur le sujet.

Commercial reflective roof coatings: why a reflective roof changes the game.

In the commercial sector, summer heat hits employees and the energy bill first.

Why offices overheat

A dark roof can hit 80°C at the surface and push that heat onto the top floors, often the hardest to occupy.

How a reflective roof works

A reflective roof pairs high solar reflectance with high emissivity to bounce back the sun and shed heat.

Comfort and working conditions

Thermal comfort shapes well-being, focus and quality of life at work through the hot months.

Keeping air conditioning in check

With less heat coming through the roof, a reflective coating eases the load on cooling equipment across large surfaces.

Reflective roofs and energy performance

By working the air conditioning line item, a reflective coating lowers the building’s consumption and strengthens its energy performance over time.

A coating that lasts

Covalba polyurethane and finishing varnish systems are designed to last 8 to 10 years while maintaining their performance.
