That heat passes through the roof and drives up the temperature inside. - [card-2-title] It ages faster - [card-2-text] UV and thermal shock cause the bitumen to chalk and then crack. The hotter the membrane gets, the more it weakens. - [card-3-title] It weighs on your comfort and your bills - [card-3-text] Under an overheated roof, teams struggle and air conditioning, where present, runs in overdrive. - [transition] Good news: the cause can be treated without touching the structure. ## [solution] Solution - [badge] The Covalba solution - [title] Your roof reflects the sun instead of absorbing it. - [text] On a bituminous membrane, the CovaTherm system goes directly over the existing waterproofing: a light-colored reflective coating that reflects up to 90% of solar radiation. The membrane no longer heats up, the building stays comfortable, and the existing waterproofing is protected from UV. If it is already worn, CovaSeal 20 restores the waterproofing and cools the roof in a single operation. - [system-title] The 3-layer system - [system-1] Bonding primer suited to bitumen - [system-2] CovaTherm 8 polyurethane base coat - [system-3] CovaTherm 20 top coat for long-term durability - [cta-label] View the CovaTherm data sheet ## [benefits] Benefits - [badge] What you gain - [title] Cooler underneath, more durable on top. - [featured] Up to -8 to -10°C under the roof, from the very first summer. - [card-1-title] A cooler building - [card-1-text] Heat no longer comes through the roof. Top floors become comfortable again without running more air conditioning. - [card-2-title] Extended waterproofing life - [card-2-text] Protected from UV and thermal shock, your membrane gains 8 to 10 years of service life. - [card-3-title] A lower bill - [card-3-text] On air-conditioned buildings, cooling units work less hard. - [card-4-title] A major project postponed - [card-4-text] You push back the roof replacement, a far heavier investment. ## [roi] ROI - [badge] The smart calculation - [title] Postpone re-roofing without taking the building out of service. - [intro] As long as the membrane remains viable, the cool roof coating treats the heat and protects the waterproofing for a fraction of the cost of a re-roofing. - [after-comparison] The logic is simple: less heat starting this summer, and a major expense pushed back. - [situation-header-1] Your situation - [situation-header-2] What we recommend - [situation-header-3] Why it's the smart calculation - [situation-row-1-col-1] Sound membrane exposed to heat - [situation-row-1-col-2] CovaTherm cool roof coating - [situation-row-1-col-3] Minimal investment, immediate comfort, extended waterproofing life. - [situation-row-2-col-1] Aging membrane - [situation-row-2-col-2] CovaSeal 20 - [situation-row-2-col-3] Restores the waterproofing and cools the roof for about a quarter of the price of a new membrane. - [situation-row-3-col-1] Active leaks - [situation-row-3-col-2] Repair of detail points then CovaSeal 20, or a new membrane if too far gone - [situation-row-3-col-3] We won't apply CovaTherm over failed waterproofing — and we'll tell you so honestly. - [situation-row-4-col-1] Insufficient insulation - [situation-row-4-col-2] Cool roof coating for summer, to weigh against a full re-roofing if insulation is the real issue - [situation-row-4-col-3] The cool roof addresses summer; it does not replace insulation. - [cta] Request a quote ## [mid-cta] Intermediate CTA - [title] Gain cooling without re-roofing your bituminous roof. - [text] Tell us about your roof and we'll help you assess the condition of the membrane, estimate the potential thermal gain, and determine whether CovaTherm is enough or whether the waterproofing needs to be redone first. ## [compatibility] Compatibility - [badge] What it works on - [title] Compatible with your membrane, after a technical assessment. - [text] The system applies to most bituminous membranes: bare bitumen, mineral-surfaced (self-protected) membrane, and multi-layer. It all starts with an assessment of the waterproofing and the detail points. The roof is cleaned, detail points are repaired if needed, then the primer ensures adhesion before application. ## [method] Method - [badge] A safe job site - [title] Everything happens from the outside, without hauling equipment onto the roof. - [step-1-title] Technical assessment - [step-1-text] Condition of the membrane, detail points, thermal targets. - [step-2-title] Preparation - [step-2-text] High-pressure cleaning and repair of sensitive points. - [step-3-title] Safe application - [step-3-text] Spray application from the outside; only the hoses go up to the roof. - [step-4-title] Inspection - [step-4-text] Quality verification and follow-up over time. - [reassurance] Equipment stays at the foot of the building, nothing on the roof. No risk to the structure or the waterproofing when applied by a trained, properly equipped contractor. ## [proof] Proof - [badge] Real results - [title] Measured in the field. - [figure-1-value] -7.5°C - [figure-1-label] on surface temperature - [figure-2-value] +8 to 10 years - [figure-2-label] of waterproofing life preserved - [figure-3-value] 80% - [figure-3-label] of CovaTherm applications are on bituminous membranes ## [faq] FAQ - [q1] My waterproofing is old, do I need to redo it first? - [a1] Not necessarily. If the membrane is sound, the cool roof coating protects and extends it. If it is chalking or shows microcracks without leaking, CovaSeal 20 restores the waterproofing and cools the roof in a single operation. A technical assessment settles it. - [q2] Does it hold on a mineral-surfaced membrane? - [a2] Yes, after suitable preparation and a bonding primer. It is one of the most common substrates for this system. - [q3] How long does it extend my waterproofing? - [a3] By protecting it from UV and thermal shock, the cool roof coating typically extends its service life by 8 to 10 years. - [q4] Do I need to strip off the old membrane? - [a4] No. High-pressure cleaning is enough, followed by repair of the detail points if necessary. - [q5] And existing leaks? - [a5] They are dealt with before any application. The cool roof coating is not a waterproofing repair; it is a protection. - [q6] And in winter, will I use more heating? - [a6] The effect is minimal. In winter the sun is low and scarce. The slight mid-season loss is more than offset by the summer gain. ## [final-cta] Final CTA - [title] Cool your bituminous roof without redoing it. - [text] CovaTherm protects your membrane, reduces the heat under the roof, and postpones a heavy re-roofing for as long as the waterproofing remains viable. - [reassurance-1] Talk to an expert - [reassurance-2] 80% of our applications on bituminous membranes - [reassurance-3] No commitment ## [seo] SEO content - [intro] The bituminous membrane is the most widespread waterproofing covering on the flat roofs of industrial and commercial buildings. Robust and proven, it has one flaw: its dark color makes it a heat collector. - [section-1-title] Why a bituminous membrane roof overheats - [section-1-text] Bitumen is dark, and a dark surface absorbs most of the solar radiation it receives. In high summer, a bituminous membrane can reach 80°C at the surface. That heat then passes through the roof and spreads inside the building. - [section-2-title] The cool roof on bituminous membranes: how it works - [section-2-text] The cool roof relies on a light-colored reflective coating with high solar reflectance applied directly onto the existing waterproofing. The CovaTherm system delivers exactly this: primer, polyurethane base coat, and finishing top coat. - [section-3-title] Cool roof coating or waterproofing replacement: the smart calculation - [section-3-text] Redoing waterproofing costs between €80 and €100/m² for a new membrane, and up to €150/m² if the insulation is redone. A cool roof coating sits at around €20 to €25/m² and pushes back the replacement. - [section-4-title] When to choose CovaSeal 20 - [section-4-text] When the waterproofing ages, chalks, or shows microcracks without leaking, CovaSeal 20 reinforces the existing waterproofing and cools the roof in a single operation. - [section-5-title] A principle backed by research - [section-5-text] Laboratories have long documented the effectiveness of reflective roofs. These figures explain the gains measured on large industrial roofs. - [section-6-title] Protection that lasts - [section-6-text] The CovaTherm system, polyurethane with a finishing varnish, is designed to retain its performance for 8 to 10 years. It is this longevity that turns the cool roof coating into an investment.
