When water becomes the real design challenge… How to protect building assets from flooding.

(MENAFNEditorial) Recent industry analysis reveals that up to 85 percent of the total cost for conventional combo roofing systems in the GCC region is directed toward thermal insulation, while only around 15 percent is dedicated to waterproofing.

With increased extreme flooding events, contractors are turning to more durable roofing and waterproofing systems

The Middle East’s evolving climate is testing the limits of conventional building envelopes. Recent unprecedented rainfall has exposed vulnerabilities in traditional combo roof systems — systems once trusted to balance insulation and waterproofing. Today, architects, civil engineers and contractors face a new challenge: designing for resilience in the face of intensifying weather extremes.

Waterproofing products with extended life expectancies such as DELTAShield Combo Max, set the new benchmark.

Rethinking roofing performance from the inside out
Beyond the visible finish and thermal insulation, the hidden waterproofing layer determines the true longevity of a roof. It’s this unseen membrane that prevents structural decay, protects interiors, and upholds the architect’s design integrity. As climate patterns shift, so too must material priorities — moving from cost-driven choices to performance-led specifications.

Experts Opinion
“Architects and developers are rethinking roofs not as barriers, but as performance systems that protect the entire building envelope, ensuring both durability and water tightness over a longer period of time.”
— Paul Symons, Sales Director, DELTA Coatings International

How can developers, architects, contractors and specifiers reduce risk and ensure the most durable roof solutions for clients?
Not all combo roof systems are created equal. While insulation foam and screed contribute to thermal comfort and energy efficiency, they are not the defining factor in a roof’s long-term performance. Water ingress remains the single greatest risk to the structural integrity of any building.

For contractors and specifiers, risk mitigation begins with choosing materials engineered for strength and endurance. High-performance polyurea waterproofing systems — long proven in industrial and infrastructure environments — now offer architects the strength and durability required for residential, commercial, and civic structures.

Key selection factors include:
•Seamless membrane integrity with no weak points or joints
•Superior elasticity and elongation, allowing for substrate movement
•High impact and abrasion resistance, eliminating follow-on trade damage
•Rapid cure times, reducing site delays and downtime

DELTAShield Combo Max Roofing System: The Difference is in the Detail
There may be dozens of “combo roof systems” available, but DELTA Coatings’ DELTAShield Combo Max stands apart — because the difference is truly in the detail.
At the heart of DELTAShield Combo Max lies a technologically advanced polyurea waterproofing layer that outperforms every traditional system on the market. It’s not just a coating; it’s a structural shield designed to deliver total waterproofing confidence:
•8x stronger than standard combo roof membranes
•3x more flexible, adapting to building movement
•10x more impact and abrasion resistant, eliminating post-installation damage
•Seamless and monolithic, bridging multiple substrates in a single spray application
•Cures in seconds, walkable within minutes — dramatically accelerating construction schedules

The result is a complete, integrated roofing system with unmatched performance and an extended design life expectancy spanning many decades.
Waterproofing products with extended life expectancies…
As recent floods have proven, the real measure of a roof is not how well it insulates but how well it protects the structural integrity of the building and everything within it. For architects and specifiers committed to durability, sustainability, and long-term design integrity, DELTAShield Combo Max is the ultimate choice.

Specialists Speak Out
“With DELTAShield Combo Max, we’ve engineered a polyurea-based membrane that doesn’t just seal — it strengthens. It is performance designed for the realities of today’s climate and is benchmarked to an extended life expectancy spanning many decades. Given recent extreme rainfall and flooding events across the Middle East and globally, this has rapidly become the new benchmark for combo roofing systems.”
