In Vietnam, the rainy and storm season is always the harshest test for any roofing system. Roofs must not only withstand long periods of heavy rain, but also strong gusts, high humidity, and unpredictable weather. If the wrong roofing material is chosen, a building can quickly face leakage, deterioration, and costly repairs.

A standard quality roof tile needs more than good looks. It must also deliver structural strength and excellent water resistance, two critical factors that keep a home safe during monsoon and typhoon months.

1. Key criteria for roofing tiles that prevent leaks effectively

Flat surface with minimal warping: Tile warping directly affects how tight the roof is. The flatter the tile, the smaller the gaps, which greatly reduces rain splash back and water penetration during heavy storms.

Well designed overflow barrier (anti-overflow ridge): This ridge works like a built-in water guide, directing rainwater to flow properly instead of spilling through tile joints. It is an essential detail that is often overlooked when selecting roof tiles.

Backside waterproof layer: In strong winds, rainwater can be pushed upward to the underside of tiles. A high-quality waterproof backing helps prevent reverse seepage, one of the most common causes of roof leakage.

2. Dong Tam Roof Tiles: Durable, safe roofing solutions for Vietnam’s climate

Developed specifically for tropical monsoon conditions, Dong Tam Roof Tiles offer an optimal roofing tile solution that balances three priorities: durability, safety, and aesthetics.

High anti-overflow ridge: A “water barrier” for stronger protection
Dong Tam’s raised anti-overflow ridge acts as a second protective layer beneath the roof surface. During heavy rain, it channels water correctly and prevents overflow through tile grooves, minimizing the risk of leaks.

Warping tolerance of only 0.6 mm: Tight, secure roof coverage
With warping limited to just 0.6 mm, installation becomes easier and the overall roof stays tightly sealed, improving resistance against wind-driven rain.

Dong Tam roof tiles offer exceptional surface precision, so the roof surface is nearly gap-free

Reverse waterproof coating: Extra defense in storms
Each tile’s underside is coated with a premium reverse waterproof layer that blocks water intrusion when facing strong winds or sideways rain. This makes Dong Tam tiles especially suitable for regions with extreme weather.

3. Alpha and Titan glazed roof tiles: Long-lasting beauty over time

Beyond structural performance, Alpha and Titan glazed roof tile lines add strong aesthetic value to any home. Their smooth glazed finish resists moss and algae, maintains color well, and performs reliably in hot, rainy climates.

With color durability warranties of up to 50 years, Dong Tam glazed roof tiles help roofs stay elegant and fresh over decades, reducing fading and preserving a high-end look.

The rainy and storm season is the most honest test for all roofing materials. Choosing the right roof tiles does more than prevent leaks. It protects the lifespan of the building and keeps the roof beautiful year after year.

With outstanding technical strength and timeless aesthetics, Dong Tam premium glazed roof tiles are the ideal choice for homes that want to withstand sun, rain, and storms, while staying sustainable over time.
