When inquiring about resin roofing tiles, the question many customers ask most often is:“How long will these tiles last? Will they fade after a few years?”
Today, I’ll explain these two issues in plain language.
How long do resin roof tiles last?
Synthetic resin roofing tiles manufactured by reputable manufacturers,The typical service life is 20 to 30 years., Some products made with highly weather-resistant ASA material can last for more than 30 years in actual use.
There are three key factors that affect lifespan:
| Factors | Note |
|---|---|
| Raw material quality | Roofing tiles made from brand-new ASA+PVC resin offer far superior weather resistance compared to products made from recycled materials, which is the key factor determining their lifespan. |
| Production Process | Roof tiles made using a four-layer co-extrusion process in a single molding step do not delaminate or crack; roof tiles produced using the calendering process at small workshops may crumble within two or three years. |
| Installation Guidelines | Whether the overlap length is sufficient and whether the screws are tightened properly directly affect whether water leakage and deterioration will occur later on. |
In short:With the right materials, the right manufacturing process, and the right installation method, it will last for over 25 years with absolutely no problems.
Do resin roof tiles fade?
Yes, but genuine products fade very slowly.
All outdoor building materials will experience some degree of color fading due to exposure to ultraviolet rays—this is a natural phenomenon. However, there is a significant difference between high-quality and low-quality roof tiles:
- Low-Quality Recycled Roofing Tiles: It fades noticeably within 1–2 years, the surface becomes powdery and whitish, and powder comes off when touched by hand.
- Genuine ASA Tiles: Color difference does not exceed 5% within 5 years, and the original color remains at 70% or higher after 10 years.
The key lies inThickness and Quality of the Top-Layer ASA Weather-Resistant Coating. National standards require that the ASA layer be at least 0.15 mm thick, while high-quality brands generally make it 0.2 mm or thicker, which doubles its weather resistance.
How can you tell if the roof tiles you bought are durable?
Just remember these three points:
- View the test report—Are there any national-level weather resistance test results or accelerated aging test data?
- See the Ingredient Claims—Is it brand-new, virgin 100% material? Are you willing to include that in the contract?
- Check the warranty period—If a product comes with a warranty of 20 years or more, it’s unlikely to be subpar.
How long do resin roof tiles last? What is their typical lifespan, and do they fade?
Resin roofing tiles are not disposable items,Spend a little more when you buy it, and enjoy ten years of worry-free use. Before selecting roof tiles, it’s best to clearly verify the raw material certifications and warranty terms—that’s the most reliable approach.
