Looking for Winter Roof Leakage Waterproof Coating Solution in the Middle East?

In the Middle East, harsh winter winds, sudden downpours, and moisture seeping into even the smallest cracks in the roof can all cause leaks.

Let us guide you through the causes of winter leaks, how to repair them, and how to prevent future leaks.

What causes roof leaks in winter?

Winter is the main rainy season in the Middle East. Although rainfall is less frequent, it can occur in short bursts of heavy rain or even downpours, easily causing localized water accumulation. These factors can also lead to gaps in the roof, resulting in leaks.

• Climate Change: Hot summers cause materials to expand, while low winter temperatures cause them to contract. This can easily cause slight displacement of the roofing materials, creating gaps and leading to leaks.
• Strong Winds and Rain: Cold air masses in the Middle East are accompanied by strong winds, which can blow rainwater under the roof tiles and into the gaps in the roof.
• Clogged Drainage System: Strong winds in winter can cause sand and debris to clog roof gutters. This can lead to water accumulation on the roof.
• Low-quality waterproofing coatings: Low-quality waterproofing coatings age and fail over time, cracking and losing their waterproofing ability.

Optimal Roof Waterproof Coating Solution For Winter Roof Leaks

Tengyu sealants utilize roof waterproof coating solution specifically designed for roofs in the Middle East. In the Middle East, roof waterproofing systems must simultaneously withstand the dual challenges of winter temperature fluctuations and rainfall, and summer extreme temperatures and UV radiation. Considering overall elasticity and long-term weather resistance, the high-elasticity polyurethane waterproofing coating system is the optimal solution for roof waterproofing in the Middle East.

Key Challenges of Roof Waterproofing in the Middle East

Waterproofing systems suitable for Middle Eastern roofs should possess the following core properties:

• Stable application under mild winter conditions
• High elasticity, bridging micro-cracks in the substrate
• Rapid surface drying, reducing the risk of rain damage
• Long-term resistance to high temperatures and UV aging
• Strong adhesion to concrete and masonry substrates

TW330 Exposed Solvent-Based Polyurethane Waterproof Membrane

TW330 polyurethane waterproof coating for roof is a single-component, high-solids, exposed polyurethane waterproofing coating designed specifically for concrete roofs and walls, particularly suitable for the climate and construction environment of the Middle East.

1️⃣ Suitable for Middle Eastern winter construction conditions

• Single-component system, easy application
• Normal film formation above 5°C
• Surface drying time of approximately 6 hours, effectively reducing the risk of sudden winter rainfall

During the limited construction time in the Middle East winter, TW330 can cure stably, avoiding coating failure due to low temperatures or dampness.

2️⃣ High elasticity, adaptable to diurnal temperature variations

• Elongation at break: 659%
• Tensile strength: 6.0 MPa
• Tear strength: 18 N/mm

3️⃣ Long-term weather resistance suitable for exposed roofs

• Heat shrinkage: -0.8%
• High solids content (89%)

TW330 waterproof coating for roofs can withstand long-term exposure to high temperatures and strong UV radiation in the Middle East without powdering, cracking, or shrinkage deformation.

4️⃣ Reliable waterproofing and adhesion performance

• Water pressure penetration test (0.3 MPa / 120 min): PASS
• Water absorption: 3.1%
• Adhesion to concrete: 1.2 MPa

How to prevent roof leaks in future winters?

• Clean the roof gutters before winter arrives, ensuring thorough removal of all debris from gutters and eaves.
• Uses high-quality waterproof coating
• Immediately seals visible cracks on metal roofs

TW330 exposed polyurethane waterproof coating combines high elasticity, low-temperature resistance, and weather resistance to provide a complete roof waterproofing coating solution for Middle Eastern winter roofs. It effectively bridges micro-cracks, resists winter downpours and cold winds, and provides long-term reliable waterproof protection for Middle Eastern roofs.
