Hai cách chống dột mái nhà & chống thấm tường gạch (Làm sai là dột mãi)

Roof leaks aren't caused by holes… but by water finding its way in. This video shows you two ways to fix the problem at its root: 1. Pipes penetrating tile roofs: If not sealed properly, water will seep in through the pipe. 2. Walls adjacent to metal roofs: If there isn't a proper seal and overlapping, water will cling to the wall and flow back inside. 👉 Important point: It's not about sealing… but about directing the water in the right direction. Doing these two things correctly will prevent leaks even during heavy rain. #roofleakprevention #waterproofing #metalroofrepair #roofrepair #waterproofing #fixroofleak #homerepair #diyhome #constructiontips #beautifulhome Disclaimer: This video is intended for educational and illustrative purposes under the principles of Fair Use.
