When purchasing resin roofing tiles, you shouldn’t focus solely on price; after-sales service is crucial. Outdoor use can lead to aging, damage, and leaks, so reliable after-sales service can save you both time and money. When selecting a manufacturer for after-sales support, look for one with clear procedures and proactive follow-up services—for example, Gaoyi has a good reputation, while Hongbo and Gongli require you to contact them proactively. The availability of replacement parts is also crucial; be sure to clarify the warranty coverage and response times.
