How a Meydan townhouse roof is actually built

The build-up is the standard UAE combo roof, with the waterproofing and the thermal insulation installed as one system. From the ceiling upwards:

1. The structural concrete slab.
2. A screed laid to a fall so water runs towards the outlets rather than sitting.
3. The waterproofing membrane itself.
4. A separation or protection layer.
5. Thermal insulation boards.
6. A protective screed, commonly around 80mm.
7. The visible finish: tiles, gravel or a reflective coating.

The consequence is the part owners are rarely told. On a combo roof the waterproofing sits buried under the screed and the finish, so it cannot be seen or inspected from the roof surface. Reaching it means lifting what is above it.

The difference on a townhouse is the shape. The roof is narrow, it abuts the neighbouring property on one or both sides, and it carries the same AC plant, pipework and tank arrangement that a much larger villa roof carries. The equipment does not scale down with the plot.

Why a small roof is not a cheap roof

Cost on a roof follows the length of the detailing, not the area of the deck. A square roof of 100 square metres has 40 metres of perimeter. Cut that roof into a narrow townhouse strip of 60 square metres and you can still be detailing a similar length of edge, now across a smaller area. The rate per square metre rises because the square metres are doing less of the work.

On the MAG Eye roof the quote noted a high density of joints and abutments. That is the phrase that explains the rate. Every junction between the deck and a party wall, every abutment against a neighbouring structure, every change of level has to be opened, sealed, reinforced and taken up and over with a secure termination.

What the old patches were hiding

The roof had been patched before, more than once, in the places where it had leaked. Patch repairs are not a criticism of whoever did them. They are what gets done when a leak appears and the budget is a call-out rather than a roof.

The problem is what a patch does to the next job. Each one is a different material, applied at a different time, with a different edge where it meets the roof. You cannot lay a continuous membrane over a surface made of six other membranes and expect it to behave as one system. Our scope started with removing the old patches, and that removal is part of why the rate was AED 350 per square metre rather than a standard flat roof figure.

How we work in Meydan

Clean the roof down to something the membrane can bond to. Remove the old patch repairs. Open and seal every crack and joint, then cover them with elastic joint tape. Treat each abutment and upstand individually, with a reinforcing strip embedded at the angle and the membrane carried up and over the edge with a secure termination.

Then the membrane itself: Sikalastic-525 RoofPro GCC, base coat at 1.2 kg per square metre, reinforcing fleece across the entire surface, top coat at 0.8 kg, total 2.0 kg per square metre. Reinforcement across the whole roof rather than only at the joints, because on a roof with this much junction the whole roof is close to a junction.

Work is booked around whatever hours the community permits, and the roof is left clean.

What roof waterproofing costs in Meydan

The published range for Dubai is AED 130 to AED 390 per square metre. The MAG Eye townhouse roof was quoted at AED 350 per square metre over 60 square metres.

If you are comparing that against a rate someone quoted for a large open villa roof, you are comparing two different jobs. Ask any contractor quoting your townhouse how many linear metres of abutment and upstand they have allowed for. The answer tells you whether they have looked at your roof or at a calculator.

The pricing page sets out the full range, and this guide walks through reading a roof quote line by line.

Common questions

My roof is tiny. Why is the rate higher than my neighbour’s villa?

Because the rate follows detailing, not area. A townhouse roof is mostly edge and abutment, and edges take time and material. The total bill is still lower than the villa’s. The rate is not.

Can you just repair the patch that is leaking?

We can, and sometimes we recommend it. But if a roof has already been patched several times, each patch is a new edge and a new candidate for the next leak. At some point repeated repair costs more than doing it once.

Will you need access through my neighbour’s property?

Normally no. Where an abutment is shared we work from your side and terminate at the boundary. If access genuinely is needed we tell you before you accept the quote, not after.

Do you need a permit from the community?

Usually yes for townhouse communities. We prepare the scope of work, method statement and risk assessment the association asks for, and we do not start until the permit is issued.
