Roof flashing system Bandar Utama | TTDI :the key barrier for building waterproofing #roofingrepair

The roof flashing system is the core component of the building envelope waterproofing system, which is mainly used to solve the leakage problem at the junction of the roof and the vertical facade (such as parapets, chimneys, skylights, etc.). The system forms a continuous and durable waterproof barrier at the structural joints through the synergistic effect of metal flashing plates and sealing materials, effectively resisting rainwater erosion and ensuring the long-term safety of the building.
Technical points
1. The first line of defense for waterproofing
Highly durable materials such as 304 stainless steel or rust-proof aluminum plates are used, combined with mechanical fixing and sealant composite technology to ensure reliable sealing at special-shaped joints.
2. Strengthening weak links
For high-risk leakage areas such as roof penetrations and deformation joints, strictly follow the node reinforcement standards of the "Technical Specifications for Roof Engineering" (GB50345-2012) to improve the overall waterproof performance.
3. Systematic protection
The flashing system needs to work in conjunction with waterproof membranes and drainage facilities and be included in the annual maintenance plan. Regular inspections should be conducted for metal corrosion, sealant aging, and structural displacement to ensure long-term effectiveness.
Maintenance recommendations
- Inspection cycle: Special inspections should be conducted once before and after the flood season each year
- Key maintenance items: Metal component corrosion, sealant cracking, and joint deformation
Scientific and reasonable flashing system design and regular maintenance can greatly extend the service life of building roofs and reduce the risk of leakage. It is a key link that cannot be ignored in building waterproofing projects.
