In the field of high-end villa construction, the roof is not only the “fifth facade” of the building, but also the core element that showcases the owner’s taste and ensures the quality of living. Faced with extreme climate challenges and increasingly high environmental standards, traditional tiles, clay or pure metal roofs are no longer able to meet the demands of the high-end market. Stone coated metal roofs are becoming the preferred solution for villa projects worldwide due to their natural stone aesthetic performance, excellent performance of metal materials, and green and sustainable nature.
一、 Why do top architects recommend stone coated metal roofs?
- Visual Expression Revolution: Recreating the Soul of Natural Stone
We offer over a variety of classic stone texture colors, ranging from Tuscan warm yellow to Nordic cold gray, with a color difference control accuracy of Δ E ≤ 1.5, ensuring color consistency for large-scale paving.
Light and shadow dynamic effect: The surface microcrystalline structure can produce a hierarchical gradient with the change of light angle, which increases the three-dimensional sense by 300% compared to flat metal tiles.
- Exceeding the ultimate performance of traditional materials
Ability to withstand extreme weather conditions:
Wind resistance level Class 4 (ASTM D3161), capable of withstanding typhoons of level 17 (60m/s)
Salt spray resistance test for over 5000 hours (ISO 9227), suitable for coastal and high humidity areas
Fire rating A (ASTM E108), flame retardant temperature up to 1200 ℃
Long lifecycle:
The metal substrate is coated with aluminum zinc alloy, which has 4-6 times the corrosion resistance of ordinary galvanized steel plate
Within the 50 year warranty period, there is no structural damage, and maintenance costs are reduced by 70% compared to traditional tiles
- Hidden “smart roof” genes
Thermal energy management black technology:
Reflective coating can reflect 85% of solar radiation heat (Solar Reflectance Index ≥ 82), and the surface temperature of the roof in summer is 40 ℃ lower than that of asphalt tiles
Rain noise reduction system:
The surface layer is the particle structure sound-absorbing layer, and the decibel value of rain noise is ≤ 35dB (ordinary metal roofs ≥ 65dB)
Meet the highest level requirements of the “Code for Sound Insulation Design of Civil Buildings”
二、 Four disruptive advantages of stone coated metal roofs
| Comparative dimension | Traditional clay tiles | natural stone slabs | stone coated metal roof |
| Weight | 45-60kg/㎡ | 80-100kg/㎡ | 6.5-8.5kg/m2 |
| Installation cycle | 15-20 days (300 ㎡) | 25-30 days (300 ㎡) | 3-5 days (300 ㎡) |
| Maintenance frequency | every 5 years | every 3 years | every 15 years |
| Carbon emissions | production stage 280kg CO ₂/㎡ | mining stage 150kg CO ₂/㎡ | full lifecycle 25kg CO ₂/㎡ |
| recycling value | non recyclable | Partially recyclable | 100% recyclable |
三、 The selection of global landmark villas confirms quality

五、 In depth analysis of common problems
Q： Does the renovation of the old roof require demolition?
A： 70% of the projects can be directly installed on the original roof (wooden structure/concrete), saving 30% of the renovation cost.
