How an Emirates Hills roof is actually built

Differently on every villa, which is the honest answer. What we typically encounter on one house is several of the following at once:

• Flat roof areas built as a combo roof, with the waterproofing sandwiched between the screed below it and the insulation, protective screed and finish above it.
• Terraces over habitable rooms, which are the same construction but with a bedroom rather than open air underneath, so a failure shows up inside the house within hours.
• Pitched or feature roof sections, with a sheet membrane beneath tiles or another finish.
• Plant areas carrying chillers, pumps and pool equipment, with service access and regular foot traffic.
• Roofs at three or four different levels on the same house, each draining onto or past the next.

Every point where two of those meet is a detail. The waterproofing has to be carried up the vertical face, lapped correctly and terminated so that water cannot get behind it, and on a villa like this there may be thirty or forty such junctions. Any one of them can put water into the house.

The other consequence of a custom build is that nobody has a record of what is up there. On a Springs villa we can reason from the community’s standard design. Here we cannot, so the survey does more work and the report is longer.

The three places Emirates Hills roofs leak

1. Level changes and upstands

Wherever one roof level meets a wall or a higher roof, the waterproofing has to run up that vertical surface to a proper height and be mechanically terminated at the top. Two failures are common: the upstand is too low, so driven rain or ponded water simply goes over the top of it, or it was finished with sealant rather than a termination. On a multi-level villa this is the most frequent finding.

2. Plant and equipment areas

Regular servicing means regular foot traffic, and traffic destroys a system chosen for an empty roof. This is one of the few situations where polyurethane is genuinely the right specification rather than an upsell. It is the toughest of the three coating types and it takes foot traffic and equipment loads, which is why it belongs on plant decks even where silicone is the better choice across the rest of the roof. On a villa of this size, expecting one product to cover the whole roof is the mistake.

3. Terraces over living space

The build-up is more complex than an open roof, the tolerance for error is lower because there is a room underneath, and the finish is usually a tile or stone the owner does not want disturbed. These need careful diagnosis precisely because opening one up is disruptive and expensive, so it is worth being certain first.

Drainage deserves a mention of its own. A large roof collects a large volume of water, and outlets sized for a routine Dubai shower have to cope with storms considerably heavier than that. The April 2024 storm delivered roughly 160mm of rain on Dubai in a single day, the heaviest in about 75 years, and it found the limits of a great many drainage designs across the city.

Why one rate per square metre does not work here

On a villa with a plant deck, two terraces over bedrooms, a pitched feature section and open flat roof at three levels, a single rate is either wrong or padded. Each of those areas needs a different specification, different detailing and a different amount of labour per square metre.

So quotes here are itemised by area rather than given as one number: this terrace, this system, this price; the plant deck, this system, this price. It takes longer to produce and it is harder to compare against a one-line quote from someone else, but it is the only version that survives contact with the actual roof.

It also means we can stage the work. Where the survey shows the plant deck is urgent and the main flat roof has several years left in it, that is what the report says, and you can do the urgent part now.

How we work in Emirates Hills

Every job starts with a free inspection, and the inspection is a real diagnosis rather than a man with a clipboard writing down a rate. We look at the roof as a system: access and safety first, then the overall slope and where water has been sitting, then the parapet, the movement joints and every pipe, cable and AC unit passing through the surface.

We take moisture readings across the roof, photograph every joint, drain, flashing and penetration, use thermal imaging where conditions allow, and run a flood test where the evidence calls for one. You get a written report: what is wrong and where, tied to photographs and actual readings, what is required against what is merely optional, the system we propose and the reasoning behind it, and a fixed price.

Where the membrane is otherwise sound, we recommend a spot repair rather than a full replacement. That is a stated policy, and it costs us money every time we apply it, because the full job bills more. Roof waterproofing and heatproofing carry our 10-year workmanship warranty, and keeping it active takes one short check-in a year at no cost.

What roof waterproofing costs in Emirates Hills

Roof waterproofing and heatproofing is AED 130 to 390 per square metre, depending on the condition of the roof and the system specified. The low end assumes a sound existing surface and a straightforward overlay. The high end covers a full strip-out, slope and screed correction, and a premium multi-coat system.

Large roofs with plant areas and several levels usually need more than one system, so the quote is itemised by area rather than given as a single rate. Expect the plant deck and the terraces over living space to sit higher per square metre than the open flat roof, because the specification and the detailing are genuinely heavier there.

We publish that range rather than keeping it private, because the gap between a cheap quote and a specified system is the thing most owners in Emirates Hills are trying to understand. If you have quotes in front of you now, why one quote says AED 40 per m² and another says AED 300 explains what each price actually buys. Full details are on our pricing page, and we do not quote without inspecting first.

Common questions

Why can you not give me a price per square metre over the phone?

Because on an Emirates Hills villa there is no single correct rate. A plant deck taking foot traffic, a terrace over a bedroom and an open flat roof need three different specifications. Any one number quoted before seeing the roof is either wrong for most of it or padded to cover the worst case.

Do you have to lift my terrace tiles to find the leak?

Not as a first step, and we would rather not. Moisture readings, thermal imaging where conditions allow and a flood test usually narrow the entry point down before anything is lifted. Opening a terrace is disruptive and expensive, so being reasonably certain first is worth the extra survey time.

Can you do the urgent area now and the rest later?

Yes, and on large villas that is often the sensible route. The report separates what is required from what is optional, so if the plant deck needs doing this season and the main roof has years left in it, you can act on the first and plan the second.

Is the same system used across the whole roof?

It should not be. Polyurethane takes foot traffic and equipment loads and belongs on plant decks. Silicone handles standing water and heat cycling and suits most open flat roof areas. Specifying one product everywhere either overspends on the quiet areas or underspecifies the busy ones.
