Cost guide / Roofs
Roof waterproofing cost in Dubai
What will your roof cost to waterproof? We quote after a site assessment rather than publish a standard rate per square metre. This guide explains the cost drivers and what to check when comparing quotations.
The short answer
Two roofs with the same footprint can need very different work. One may only need cleaning, minor detailing and a new coating. Another may need old layers stripped, cracks and upstands repaired, and trapped moisture dealt with before anything new goes down.
That is why a meaningful quotation follows a site assessment. The figure should describe your roof: its condition, the system chosen for it, the details around drains and equipment, and what is and is not included.
This guide does not list prices or ranges. Any figure without your site, scope and system behind it would not help you compare real quotations.
The parts of a roof quotation
- 01
Site assessment
Condition of the existing surface, signs of past leaks, ponding areas, drains, parapets and penetrations. Everything else in the quote should follow from what was found here.
- 02
Actual measured area
The waterproofed area includes upstands, parapet returns and details, not only the flat floor area on a plan. Ask how the area was measured.
- 03
Removal of existing layers
Whether old membranes, coatings, tiles or screed stay or come off changes labour, waste handling and time significantly. A quote should say which.
- 04
Surface preparation
Cleaning, grinding, priming and treating weak or contaminated areas. Preparation is where a waterproofing system succeeds or fails.
- 05
Repairs before coating
Cracks, damaged screed, loose plaster on upstands, broken drain outlets or failed joints. Some can only be fully scoped once old layers are removed.
- 06
Moisture in the roof
Water trapped beneath old layers or in the screed can affect which system is suitable and whether drying time is needed first.
- 07
Details and penetrations
AC units, pipes, skylights, drains, expansion joints and equipment plinths each need individual detailing.
- 08
Access and logistics
Stair or ladder access, lifting materials, working around tenants or occupied villas, building permissions and working-hour restrictions.
- 09
System selection
The waterproofing system, number of coats and any heat-reflective or protective top layer. Different systems are not directly comparable on price alone.
- 10
Curing and scheduling
Curing time between coats, weather and heat windows, and whether the roof must stay out of use. These affect how the work is phased.
Checklist
Comparing roof quotes like-for-like
A lower figure is only lower if it covers the same scope. Put each quotation against these questions before deciding.
Was the roof actually inspected, or was the quote based on photos or a plan?
A site visit can reveal issues that photos miss, although concealed damage may still need further investigation.
Are existing layers being removed, overlaid or partially removed?
Removal and waste handling can create a substantial scope difference between quotes.
Which repairs are included, and how are unexpected repairs handled?
Look for a clear process for work found after removal, rather than a surprise later.
What system is specified, and how many coats or layers?
Generic wording such as "waterproofing coat" makes comparison impossible.
Are upstands, parapets, drains and penetrations included and detailed?
Leaks commonly start at details, not in the middle of the roof.
Is the measured area stated, and does it include vertical surfaces?
Different measurement methods produce different totals for the same roof.
Who handles debris removal, access equipment and protection of surrounding areas?
These are frequent exclusions.
Is a water test or final inspection part of the scope?
Know how the finished work will be checked with you.
Is VAT included in the figure, or added on top?
Quotes stated with and without tax are not comparable as written.
What to have ready before an assessment
- Photos of the roof surface, drains and any visible cracks or blistering, only if they can be taken safely
- Where water appears inside, and after what kind of weather or AC use
- Any history of previous waterproofing or repairs, if known
- Equipment on the roof: AC units, water tanks, solar panels, satellite dishes
- Access route to the roof and any building or community rules on working hours
- Whether the roof will be used afterwards, for example for decoration or seating
Signs a roof quote needs more questions
- A total price with no description of preparation or removal
- No mention of drains, upstands or penetrations
- A price given before anyone has seen the roof or asked about leaks
- No list of exclusions, or no statement on whether tax is included
We quote after assessing your roof, with scope, inclusions, exclusions and tax stated so you can compare.
Common questions about quotes
Because area is only one input. Removal of old layers, repairs, moisture, details and access often change the work more than size does. A figure without those would not describe your roof, so we quote after assessing it.
It can involve less work, but it is only suitable when the existing layer is well bonded and compatible with the new system. If it is failing or holding moisture, overlaying can trap the problem. The assessment decides which approach is appropriate.
Some damage is hidden beneath existing layers. A good quotation explains how such findings are reported and agreed with you before additional work proceeds.
They are different scopes. A localised leak repair addresses a specific defect, while full waterproofing treats the whole roof surface. The assessment shows whether a targeted repair is sensible or the roof needs a complete system.
Check removal, preparation, repairs, system and coats, details, measured area, exclusions and tax side by side. The comparison checklist on this page is built for exactly that.
