At Lefong, we specialise in providing high-quality metal roof waterproofing services that utilise cutting-edge materials for unparalleled protection and durability. Our waterproofing solution includes a specialised PVDF composite functional polymer film and a composite elastic bond sealing layer, developed to offer robust protection for your metal roofing. Here’s why waterproofing with Lefong goes beyond basic protection

Why Metal Roof Waterproofing is Essential

• Leak Prevention with Advanced Sealants Our PVDF composite film is dense and highly weather-resistant, effectively blocking water and water vapour to prevent leaks over the long term. This durable layer is complemented by a specially modified butyl rubber sealant, providing an exceptionally strong and irreversible bond. This sealant, treated through a nanoscale blending process, offers multi-interface bonding that withstands both water and high-pressure vapour penetration, ensuring buildings remain leak-free for years to come.
  • Longevity: The system is designed to last over 25 years without degradation, thanks to the durable materials used.
  • PVDF Film: Offers excellent resistance against UV degradation and harsh weather.
  • Butyl Rubber Sealant: Known for its strong adhesive properties and elasticity, maintaining its integrity even under environmental stresses.
• Corrosion Prevention This advanced polymer film also prevents oxygen, acid, alkali, and salt from seeping through the roof, guarding against corrosion and extending the lifespan of your roof. This level of protection ensures that your metal roof stays resilient against environmental wear, saving you from costly repairs and replacements.

• Cooling and Noise Reduction Our product is designed to reflect sunlight and heat, helping to reduce indoor temperatures and improve energy efficiency. This cooling effect lowers carbon emissions and contributes to significant energy savings. Additionally, it has sound-insulating properties, effectively blocking sound waves to reduce noise levels indoors, making it ideal for buildings located in noisy areas.
  • Temperature Reduction: Can reduce indoor temperatures by up to 10 degrees Celsius during peak sunlight exposure.
  • Sound Insulation: The materials used absorb and block noise, enhancing indoor comfort levels.
• Weather and Fatigue Resistance: Our waterproofing product is formulated to endure extreme environmental conditions. It resists UV light, oxygen, and temperature fluctuations from -40 to 80 degrees Celsius, allowing it to maintain performance without cracking or becoming brittle. This resilience ensures that the roof can handle the natural expansion and contraction caused by temperature changes without damage.
• Wind Resistance The bonding strength of our waterproofing product is formidable. When fused with the metal surface, it creates a layer that withstands strong wind pressure without delaminating, ensuring reliable protection for high-wind areas.
  • Wind Resistance: Tested to withstand wind speeds up to 150 km/h without peeling or damage.
  • Adhesion Strength: Chemically engineered to maintain a firm grip, enhancing its resistance to wind uplift.
