Combo Roof System Waterproofing in Dubai & Across the UAE
Combo waterproofing combines thermal insulation and waterproofing into one integrated roofing solution. It’s commonly used in residential buildings, villas, and commercial rooftops across the UAE.
At Salman Syed Technical Services, we install combo roof systems with approved insulation boards, sloped screeds, and long-lasting waterproofing membranes to ensure thermal efficiency, leak protection, and compliance with Dubai regulations.
Why Combo Waterproofing Matters in the UAE
In the UAE’s intense heat, roof insulation is not just comfort, it’s a requirement. Combo roof systems reduce internal temperatures, save energy, and extend waterproofing life by placing insulation below the waterproofing layer. It’s a preferred solution in areas with direct sunlight, and it’s now standard in many residential and government projects.
Also, see our roof waterproofing page if you’re dealing with older roofs or need a non-insulated system.
What’s Included in a Combo Roof System?
Thermal Insulation Board (XPS or PIR)
Closed-cell boards placed directly on the slab, reduces heat transfer.
Slope Screed with Waterproof Additive
Provides proper drainage and prepares the base for waterproofing.
Waterproofing Membrane Layer
Bitumen-based or liquid-applied membrane is installed over screed.
Protective Screed (Optional)
Protects the membrane if tiling or mechanical damage is expected.
UV Protection (Final Layer)
If left exposed, a solar-reflective coating is applied.
We select the method based on your project’s structure, usage, and design.
