The roof takes the most sun of any surface on the building. On industrial, logistics and commercial buildings, flat roofs can hit 80°C in summer and drive indoor temperatures way up.
" }, { "question": "Will applying a reflective coating reduce my energy bills?", "reponse": "A cooler roof lets less heat into the building. In air-conditioned spaces, energy costs fall accordingly thanks to reduced air-conditioning use. The savings depend on the building, its use and its insulation level.
" }, { "question": "What ROI can I expect from Covalba reflective coatings?", "reponse": "The return on investment varies by building type and activity. The lower the temperature setpoint, the stronger the impact can be. Expect roughly 5 years for a large supermarket at 24°C, and 2 to 3 years for a refrigerated building at 4°C.
" }, { "question": "Could a reflective roof raise my heating bills in winter?", "reponse": "Solar gain through the roof stays low in winter: the sun sits lower and weaker, the days are shorter, and there's less of it. The coating mostly blocks incoming heat in summer.
" }, { "question": "Is prior authorization required?", "reponse": "We recommend checking local planning rules before any project. As a general rule, the flat roofs of industrial buildings in business or industrial zones are more easily granted approval to change roof color.

CovaTherm technology reflects 94% of solar radiation.
" }, { "question": "What is thermal emissivity?", "reponse": "Thermal emissivity is a material's ability to emit absorbed heat as thermal radiation. Covalba reflective coatings re-emit 88% of the heat they receive.
" }, { "question": "What is the Solar Reflectance Index (SRI)?", "reponse": "The SRI represents a roof's ability to reject solar heat. It is calculated according to the ASTM E1980 standard, based on solar reflectance and thermal emissivity.
" }, { "question": "What is CovaTherm's SRI?", "reponse": "CovaTherm has an SRI of 119 when new and an SRI of 118 when aged.
" }, { "question": "Do Covalba coatings contain any hazardous substances?", "reponse": "The components contain no substance classified as a chemical of concern and present no known hazard to health or the environment.
" } ], "json_ld": true }, { "layout": "faq", "entete": { "titre": "Maintenance and durability" }, "questions": [ { "question": "Is maintenance as demanding as on a conventional roof?", "reponse": "No. The system includes a finish that reduces dirt adhesion and moss growth. An annual check and a water rinse if needed are enough to preserve performance.
" }, { "question": "Is any maintenance required?", "reponse": "Covalba recommends an annual roof inspection and, if necessary, a water cleaning to remove particles that have accumulated on the coating.
" }, { "question": "What guarantees cover the product and its performance?", "reponse": "When the CovaTherm system is installed by a qualified professional applicator, it is covered by a warranty on adhesion to the substrate. A 4,000-hour accelerated aging test shows that reflective performance is maintained.
" }, { "question": "Is the waterproofing warranty kept?", "reponse": "Putting a Covalba reflective roof coating over a waterproofing system under warranty changes nothing structural and nothing about how it is used. So the waterproofing warranty stays in place.
" } ], "json_ld": true }, { "layout": "faq", "entete": { "titre": "Installation" }, "questions": [ { "question": "Does the roof structure need to be reinforced beforehand?", "reponse": "No. Applying CovaTherm poses no risk to the structure: its low weight, between 0.8 kg/m² and 1.2 kg/m², can be supported by existing roofs.
" }, { "question": "Do Covalba solutions improve waterproofing?", "reponse": "CovaTherm is primarily a thermo-reflective coating, not a primary waterproofing layer. Its continuous, thick and elastic film can, however, seal microcracks up to 2 mm and help improve overall waterproofing.
" }, { "question": "What is the impact on a photovoltaic installation?", "reponse": "A cooler roof can improve panel output during the hot season, with around 10% gain for monofacial panels and 20% to 25% for bifacial installations.
" }, { "question": "Is rainwater affected?", "reponse": "A runoff analysis carried out by an accredited laboratory found no traces of pollutants, including PFAS, in rainwater from a roof coated with a Covalba product.
