扩建的车棚屋顶出现漏水迹象，可能是由于防水措施受损或不足造成的。下雨时，水会渗入屋顶，在天花板上形成湿点和条纹，并滴落到下面的地面上。防水膜或涂层可能随着时间的推移而变质，导致水渗入表面。这个问题可能会导致进一步的损坏，例如车棚结构中的金属元素生锈或木材腐烂，因此必须解决防水问题，以防止进一步恶化。

The extended carport roof is showing signs of leakage, likely due to compromised or inadequate waterproofing. Water seeps through during rain, creating damp spots and streaks on the ceiling and dripping onto the ground below. The waterproof membrane or coating may have deteriorated over time, allowing water to penetrate the surface. This problem can lead to further damage, such as rusting of metal elements or wood rot in the carport structure, making it essential to address the waterproofing failure to prevent additional deterioration.
