Does a reflective roof coating really improve my animals' production?

Yes, indirectly but clearly. By dropping the temperature under the roof, it eases heat stress, the main reason production falls off in a hot spell.

Is the coating right for the big roofs on my livestock buildings?

Yes. The reflective coating is built for large farm roofs and works just as well on cattle housing, poultry houses, pig buildings and storage sheds.

My roof is fiber cement, maybe with asbestos. What should I do?

A reflective coating often lets you protect and cool the roof without tearing it off. Application over asbestos-containing fiber cement gets settled with your contractor during the site survey.

Does it hold up on the steel deck of my buildings?

Yes. CovaMetal 20 protects the metal from corrosion while making it reflective, ideal for agricultural steel roofs and cladding.

Does the installation disturb my animals?

No. Your contractor works entirely from the outside, with no machine lifted onto the roof. The work is organized so as not to disrupt the livestock.

And in winter, will my buildings be colder?

The effect is minimal. The winter sun is low and rarely present. The summer gain largely offsets this slight loss during the cooler months.

Why act

Under a scorching roof, your animals produce less.

Heat stress lowers production, harms animal welfare and weakens crops stored under highly exposed roofs.

Cattle suffering from summer heat during farming

Production drops

Heat stress reduces milk and egg output and slows growth during periods of intense heat.

Animals suffer

In cattle, stress begins at just 22°C: fertility, health and mortality become critical issues.

Harvests deteriorate

Grain, fodder and feed stored under an overheated roof lose quality and store less well.

Historic agricultural roof protected by cool roof

Aging roofs

Rusted steel deck or old fiber cement, sometimes with asbestos: a full tear-off runs up the bill fast.

The Covalba solution

Your roof reflects the sun instead of absorbing it.

The Covalba reflective coating bounces back up to 90% of the sun. The roof stops heating up, and the air inside the building drops by 8 to 10°C.

Conventional roof — up to 80°C at the surface

Durability

The Covalba system lasts longer on your buildings.

A coating that quickly loses its reflectivity becomes a recurring maintenance burden. Covalba systems are designed to last several summers.

Lasting performance

A coating sized for large agricultural roofs.

Large farm roofs are the main entry point for summer heat. By acting at the source, a reflective coating protects production, the herd and the structure season after season.

-8 to -10°C — under the roof
-90% — of solar radiation reflected
8-10 years — of coating durability
Passive cooling, with no energy consumption
Applied from the outside, without disrupting the livestock
Compatible with steel deck and fiber cement

Assess my buildings

Covalba helps you size the right system for the surface and condition of your roofs.

What you gain

Animals kept cool, production protected.

The coating works on the main source of heat: the roof. You feel it from the very first summer in the temperature inside the building.

-8 to -10°C

under your roof

From the first summer

Production maintained

Less heat stress to sustain milk, egg and meat production.

Animal welfare

A more temperate environment preserves the herd's health, fertility and comfort.

Harvests protected

Stored grain, fodder and feed are less affected by excessive heat.

Roof protected

The coating blocks corrosion and protects fiber cement sheets.

Better working conditions

Farmers and their teams work in a less demanding environment.

Here is how the reflective coating fits each kind of building.

Your buildings

A solution for every building on the farm.

Cattle, poultry, pigs, storage and cooperatives do not face the same heat challenges.

Cattle housing

Cattle housing and free-stall barns where thermal comfort determines milk production.

Poultry buildings

Broiler and layer houses highly sensitive to heat waves.

Pig buildings

Pig housing where heat regulation affects growth and welfare.

Harvests and fodder

Sheds for grain, hay and feed where heat degrades preservation.

Equipment and cooperatives

Large technical roofs heavily exposed to the sun.

A safe installation

4 steps. No disruption to your livestock.

Your contractor applies the coating entirely from the outside, with machines at the base of the building, without lifting any load onto the roof or disrupting the livestock.

Barn roof coating: protect livestock, harvests and the roof.

On a farm, summer heat hits production, animal health and how well your harvest keeps.

Why a farm building overheats in summer

Big steel deck or fiber cement roofs climb to very high temperatures and radiate down onto the animals or the stored harvest.

Heat stress: production and welfare

In cattle, poultry and pigs, heat drags down production, fertility, growth and health. A reflective coating cuts that heat load at the source.

The right coating for your type of building

Cattle housing, poultry houses, pig buildings, storage sheds and cooperatives all gain from a roof that soaks up less sun.

Farm steel deck and fiber cement

On steel deck, CovaMetal 20 takes on heat and corrosion at once. On old fiber cement, the coating protects and cools without a systematic tear-off.

Protection that lasts

Covalba polyurethane systems with a protective topcoat are designed to last 8 to 10 years and preserve the roof.
