Durability is another hallmark of flat slate roof tiles. Properly installed slate roofs can last over a century, making them one of the longest-lasting roofing materials available. Their ability to withstand harsh weather conditions, including heavy rain, snow, and extreme temperatures, is a significant advantage. Unlike other roofing materials, slate is not prone to cracking, warping, or fading. This resilience means that homeowners can save money on repairs and replacements in the long run, making slate a worthwhile investment.
