Under normal use, Gao Yi tiles have a service life of approximately 20–30 years, depending on climate and installation quality. They are UV-resistant and resistant to acids and alkalis; however, in coastal areas, their lifespan is reduced to approximately 20 years due to salt fog, while in temperate climates, they can last 25–30 years. Installation techniques are critical: proper handling of details such as overlaps, waterproofing, and fastening can extend their lifespan, whereas improper installation can have a significant negative impact.
