On average, asphalt shingle roofs can last anywhere from 15 â€“ 30 years while a slate roofing can survive for more than 100 years. 4. Maintenance Slate tiles are inherently fragile and can easily break when poorly handled or stepped on. This is precisely why maintaining a slate roof takes more patience and hard work. 5.
