Quick Answer
Tesla Solar Roof tiles have undergone rigorous testing and meet or exceed industry standards for hail resistance, with some models capable of withstanding impacts from hailstones up to 1.25 inches in diameter.
Hail Resistance Testing
Tesla Solar Roof tiles have been tested for hail resistance using the UL 710 Standard for Asphalt Shingles, which is used by the roofing industry to evaluate the impact resistance of roofing materials. The testing involves firing hailstones at the tiles from a height of 20 feet, and the tiles are considered acceptable if they can withstand impacts without sustaining significant damage.
UL 710 Test Results
According to Tesla’s documentation, the Solar Roof tiles have achieved a Class 4 rating under the UL 710 Standard, which is the highest rating available. This means that the tiles can withstand impacts from hailstones up to 1.25 inches in diameter, which is significantly larger than the average hailstone. In fact, Tesla’s testing has shown that the Solar Roof tiles can withstand impacts from hailstones up to 1.75 inches in diameter, although this is not the official rating under the UL 710 Standard.
Installation Considerations
While the hail resistance of Tesla Solar Roof tiles is a major advantage, it’s essential to note that the installation of the tiles is also critical to their performance. The tiles must be installed correctly, with proper sealing and flashing to prevent water intrusion. Additionally, the tiles should be installed in a way that allows for adequate ventilation and drainage to prevent damage from snow and ice. By following these installation guidelines and using high-quality materials, homeowners can enjoy the benefits of hail-resistant Solar Roof tiles for years to come.
