Villa roofs sealed to a written specification.

Less than most companies claim, but it's real. Published UAE villa studies show roughly 0 to 7 % lower annual electricity from the roof alone. Your result depends on how well the roof is already insulated and how reflective it is today. For a typical 200 m² villa roof, our estimate is about AED 150 to 1,000 a year on an insulated combo roof, and up to about AED 2,000 a year on a poorly insulated or dark roof. These figures use today's DEWA tariff and are estimates, not a guarantee. We show the full calculation in our cool roof guide.

Most Dubai villa leaks start at details, not in the open roof: cracked screed joints, failed sealant, drains, AC plinths, pipe and cable penetrations, and parapet upstands. In a typical combo roof the actual waterproofing layer is buried under the screed, so water can travel along it and appear on a ceiling metres away from where it entered. That's why we inspect with a thermal imaging camera and moisture readings rather than guess.

Henkel Polybit Polythane P: a single-component, hybrid polyurethane liquid membrane that is UV-stable and needs no topcoat. On absorbent concrete we prime first. Corners, drains and penetrations are reinforced with reinforcing fleece, movement joints are sealed with Polyseal 1PU and backer rod, and damaged screed is repaired with Polycrete repair mortar before coating. The membrane goes on in three coats, about 2.4 L/m², which the datasheet rates at about 1.5 mm dry film thickness.

The Sorento Roof System starts from AED 249/m² excluding VAT, with a fixed written quote after a free inspection. The minimum job is AED 3,000 for spot repairs; a full roof starts at 60 m². A typical 200 m² villa therefore comes to about AED 47,500 to 57,500 excl. VAT as an indicative range. Use our online estimator for a low and high band in three short steps.

Watertightness of the roof areas and details we waterproofed, for 10 years from completion. It is a **10-year written warranty by Sorento**, issued by the licensed contractor who did the work, not by Henkel. You get a serial-numbered certificate with a QR code that you, or a future buyer, can scan to verify the roof, date and test records. The certificate states the exact terms and exclusions, such as damage caused later by others drilling through the membrane.
