Asphalt could have other materials like fiberglass, minerals, metals, and cellulose, etc. These materials can increase strength and stability factors. The probability of damages will depend on the size and weight of hail-stones.
Shingles made from the combination of asphalt, fiberglass, and minerals can have longer durability and resistance to damages. There are no rules for determining the durability factors because the intensity of hails can be unpredictable.
Composite materials are also more resistant to water absorption, humidity, and algae formation. Any roof made of such materials can last relatively longer. So, you can inspect your roof once in six months.
