About the System
What is Green Combo Roofing?
The Green Combo Roofing System is an advanced dual-purpose roof solution designed to provide waterproofing and thermal insulation for concrete roofs, podium decks, and terraces in a single integrated build-up.
Trusted across Dubai, Abu Dhabi, Sharjah, and other UAE cities, this system delivers long-lasting durability, energy efficiency, and protection against extreme temperatures – ideal for residential, commercial, and industrial roofs. By placing thermal insulation above the waterproofing layer, the slab is shielded from temperature fluctuations and the building’s HVAC load is dramatically reduced.
Why Green Combo
Four Reasons the UAE Specifies This Green Roof System.
The system delivers superior protection – and pays for itself in energy savings over its 20–25 year service life.
Prevents Water Leakage & Dampness
Ensures watertight performance in the UAE’s hot, humid climate – sealing the slab against every form of moisture ingress.
Reduces Heat Transfer
Reduces heat transfer through concrete slabs, keeping buildings cooler and significantly lowering electricity costs.
Extends Roof Life
Shields concrete from UV radiation and thermal stress – extending the structural life of the slab itself.
Enhances Energy Efficiency
Minimises HVAC cooling loads for residential and commercial buildings – verified in Dubai projects to cut cooling demand.
System Cross-Section
Anatomy of a Two-in-One Green Roof System.
The Green Combo system is a layered build-up – each layer engineered to do a specific job, working together to deliver both waterproofing and thermal insulation in one installation.
-
01
Insulation Above the Waterproofing
Thermal insulation placed above the waterproofing layer shields the slab from temperature fluctuations – preventing thermal cracking and condensation.
-
02
PU Foam at 70mm Thickness
Spray-applied polyurethane foam at 70mm average thickness (density 40–45 kg/m³) – the system’s primary thermal barrier.
-
03
Geotextile Separation Layer
100–120 gsm geotextile with 20cm overlap separates and protects the foam from the protective screed above.
-
04
UV Resistant Topcoat
Final coat of acrylic, UV-resistant, highly flexible coating finishes the system – built to take the UAE sun for decades.

Step by Step
Our 9-Step Green Combo Installation.
Each step is sequenced to ensure the dual-function build-up – waterproofing and thermal insulation – performs together for two decades or more.
-
01
Surface Preparation
Thoroughly clean the roof – remove dust, debris, oil, and loose particles. Repair cracks, honeycombs, or damaged sections with suitable cementitious repair mortars to ensure a sound, uniform substrate.
-
02
PU Foam Spray
Spray application of polyurethane foam at 70 mm average thickness (density 40–45 kg/m³) – the system’s primary thermal insulation layer.
-
03
Rubberised Coating
Brush-apply rubberised protective coating over the PU foam – sealing the insulation and adding waterproof protection.
-
04
Geotextile Separation
Loose-laid geotextile separation and protective layer at 100 or 120 gsm – with 20 cm overlap between sheets.
-
05
Ridge Panels
Fix ridges in panels to create proper drainage slope of 1:100 to 1:150 – critical for shedding rainwater.
-
06
Protective Screed
Supply protective screed layer concrete to slope (1:100–1:150) protecting the system from foot traffic and finishes above.
-
07
Angle Fillets
Fix angle fillets along the parapet, mechanical duct openings, and pre-utility upstands – sealing every detail where leaks typically start.
-
08
Backing Rod & Sealant
Fix backing rod and heavy-duty polyurethane or polysulphide joint sealant to all joints in the concrete.
-
09
UV Resistant Topcoat
Apply final coat – acrylic, UV-resistant, highly flexible – above screed and angle fillet. The system’s outermost weather-facing layer.
Why Green Combo
Six Advantages of Choosing a Green Roofing System.
Every advantage solves a specific challenge that single-purpose roof systems can’t address.
Two in One System
Fully waterproof AND thermally insulated – eliminating the need for two separate installations.

Green Combo Roofing FAQs.
The questions Dubai property owners ask most about dual-purpose Green Combo roof systems.
What is the Green Combo Roofing System?
The Green Combo Roofing System is an advanced, dual-purpose roof solution designed to provide both superior waterproofing and highly effective thermal insulation in a single integrated build-up.
Where is the Green Combo Roofing System primarily used?
It is used across various applications such as residential buildings, commercial complexes, and industrial facilities – anywhere concrete roofs, podium decks, or terraces need waterproofing combined with thermal insulation.
What are the main benefits of choosing Green Combo?
The main benefits include preventing water leakage and dampness, significantly reducing heat transfer to keep buildings cooler, extending roof life by shielding concrete from UV and thermal stress, and lowering HVAC energy bills.
How long does the Green Combo Roofing System typically last?
When properly installed using quality materials, the system offers a long lifespan – typically ranging from 20 to 25 years.
Is the system suitable for green roofs or landscaped areas?
Yes. A key advantage is that the system is root-resistant – making it perfect for incorporating green roofs, landscaping, or garden areas on terraces.
Does the system help in reducing energy consumption?
Absolutely. By providing excellent thermal insulation, the system drastically reduces the amount of heat transferred into the building. This significantly lowers electricity bills, contributing to energy-efficient buildings.
Can the Green Combo Roof System be applied to existing roofs?
Yes – the system is highly versatile and is compatible with both new construction and the refurbishment of existing concrete roofs.
What kind of final layer or finishing is applied over the insulation?
A protective layer is applied over the thermal insulation, which can include a screed (cementitious layer), a top coating, or a UV-resistant finish – depending on whether the roof will be trafficked or landscaped.
How does the system prevent thermal cracking in the concrete roof slab?
By placing the thermal insulation above the waterproofing layer, the insulation shields the concrete slab from extreme temperature fluctuations. This prevents the thermal cycling that causes concrete cracking.
What maintenance is required for Green Combo in the UAE climate?
The system is highly durable and low-maintenance. We recommend routine inspections on an annual basis – checking for any damage at the parapet, drains, and surface coating.
