If you’ve followed the renovation of older residential communities, you’ve surely heard the term ”flat-to-sloped roof conversion.”
The term “flat-to-sloped roof conversion” refers to the process of converting the flat roof of an older house into a sloped roof. In this field, resin roofing tiles now account for more than 60% of the market.
Why Choose Resin Roof Tiles? Three Reasons—All of Which Are Essential.
First, the policy is being implemented.
In 2025, the General Office of the Communist Party of China Central Committee and the General Office of the State Council issued the ”Opinions on Continuously Advancing the Urban Renewal Initiative.” In 2026, the State Council’s Executive Meeting reviewed and approved the “15th Five-Year Plan for Urban Renewal,” with the renovation of old residential communities identified as a key task. Many localities have already included resin roofing tiles in their recommended catalogs of green building materials, and products with B1-grade flame retardancy and recyclability are given priority in government procurement.
Second, old houses can't support heavy loads.
The biggest challenge in replacing flat roofs with pitched roofs is the limited load-bearing capacity of older buildings. Resin roof tiles weigh only one-tenth as much as traditional clay tiles, placing virtually no additional strain on the existing structure—something other materials struggle to achieve.
Third, construction is fast and causes minimal disruption to residents.
Resin roof tiles have an effective width of 800 mm, making installation highly efficient. Combined with their light weight and comprehensive range of accessories, the construction timeline is significantly shorter than that of traditional roof tiles. For older residential communities where residents are still living on-site, the short construction time is the biggest advantage.
It’s fair to say that resin roofing tiles are practically tailor-made for flat-to-sloped roof conversion projects. With policy incentives and performance that meets the requirements, it’s hard for them not to be a hit.
