Metal roofs are generally known for their durability and resistance to leaks after applying sealant to the gaps between panels and fasteners. But they can still develop leaks under certain conditions. Proper installation is crucial; any errors during installation can lead to issues. Over time, metal roofs can also suffer from wear and tear, such as damage from hail, falling branches, or foot traffic. นอกจากนี้, sealant around fasteners, vents, and roof penetrations can degrade, causing leaks. Regular maintenance and inspection can prevent such issues. If a leak is detected, it is important to address it promptly to avoid structural damage and further complications. With proper care, a metal roof can last for decades without leaking problems.
