A Dubai cost guide benchmarks common roof membranes at AED 40–90 per m²↗. On a 250 m² villa roof that is AED 10,000 to AED 22,500 of membrane work. Whole-job figures for a villa roof run AED 4,500–15,000+↗ in that guide, AED 5,000–25,000↗ from a Dubai waterproofing contractor, and AED 6,000–12,000↗ for a medium villa from a maintenance company. Small repairs are priced as jobs, not by area: AED 800–2,500↗.
What the per-square-metre rate covers
The rate is for laying a membrane on a roof that is ready for it. A prepared roof means the surface is sound and clean, the falls run to the drains, and the contractor can start work rather than demolition. Anything before that, such as stripping old bitumen, cutting out blown screed or rebuilding an upstand, is separate money.
The cost guide publishes one blended figure for "common membrane systems" and does not split it by material. One Dubai maintenance company does publish ranges by method: AED 35–75 per m²↗ for torch-on bitumen with a protective coating, and AED 40–80 per m²↗ for liquid-applied membranes. That is a single firm's price list rather than a market survey, but it lands in the same territory as the blended benchmark.
A worked example: a 250 m² villa roof
Take a two-storey villa in Mirdif with a flat roof of roughly 20 by 12.5 metres, minus nothing for the stairwell because the membrane runs around it anyway. At AED 40–90 per m²↗, the membrane work comes to AED 10,000 to AED 22,500.
Now put that beside the whole-job brackets. The top of the per-metre sum, AED 22,500, is well above the middle of Bestimate's villa bracket (AED 9,750), which suggests that bracket has smaller roofs or simpler work in mind. The figures are not contradicting each other so much as answering slightly different questions. Across all three sources, a quote between AED 4,500 and AED 25,000 for a roof that size sits inside what has been published.
Bestimate publishes AED 4,500–15,000+ for a full villa roof. Dubai Roof Seal publishes AED 5,000–25,000. MAE Technical Services publishes AED 6,000–12,000 for a medium villa roof and AED 12,000–25,000 for a large villa or commercial roof. The first two brackets overlap, but their upper ends are AED 10,000 apart.

Why the published brackets disagree
Mostly because each one summarises different work under the same heading. Bestimate is a cost guide written for people planning a spend. Dubai Roof Seal is a contractor that also works on warehouses and commercial roofs. MAE Technical Services is a general maintenance company that splits villas into medium and large without saying where the line falls. None of them says what size of roof or how many details its figure assumes, so the spread between them is best read as uncertainty rather than as a verdict on any one firm.
That is the practical reason to price by area first. A 250 m² bare slab and an 80 m² terrace surrounded by planters can both count as "a villa roof" in a bracket, and look nothing alike in a quote.
Warehouses, sheds and commercial roofs
Industrial and commercial roofs move in a different range, mostly because they are bigger and often metal rather than concrete. Dubai Roof Seal publishes whole-job figures for each.
Dubai Roof Seal publishes AED 5,000–25,000 for a villa roof, AED 15,000–90,000 for warehouses and metal sheds, and AED 15,000–150,000+ for commercial flat roofs.

What pushes a Dubai quote up
Removing what is already there
The line people forget most often. Dubai Roof Seal says removal and surface preparation are about 30% of the total project cost↗. On a roof that has been patched three times with different products, a share like that is to be expected, because all of it has to come off before anything new goes down.
Everything sticking out of the roof
Membranes fail at edges, not in the middle. Every AC plinth, pipe penetration, drain and parapet junction is a detail that has to be cut, dressed and sealed by hand. A roof with two drains and a stairwell is priced very differently from an identical area with nothing on it.
Getting up there
Villas are easy. A tower roof, a shaded courtyard between blocks or a warehouse with live operations underneath all add cost, yet none of the sources here puts a percentage on it. Ask for access to be a separate line so you can see what you are paying for it.
What the removal reveals
The cost guide says plainly that its numbers are planning benchmarks, not fixed prices↗, and that final prices depend on hidden repair work. Wet insulation, a slab that has been ponding for years, corroded drain outlets: none of it is visible until the old layers are off.
Gaps in the published figures
Two things would make this page more useful and are missing because we could not find them published anywhere we could check: a percentage for high-rise or restricted access, and a per-square-metre price for EPDM or PVC sheet on a villa. If a figure like that appears in a source that can be linked and dated, it will be added here with both.
Before you accept a number
Run your area through the calculator to get your own range, then read how to read a waterproofing quote so you can tell whether three prices in front of you are for the same job. If the roof is leaking now, the question is whether you need a repair or the whole roof redone. For bathrooms and wet areas, the brackets are on a separate page.
