Slate roofs are roofing systems made from natural slate, a type of metamorphic rock. They are known for their durability, longevity, and aesthetic appeal. Slate can last over a century when properly maintained, making it a popular choice for historic and high-end homes. In addition to their long lifespan, slate roofs are fire-resistant and can withstand harsh weather conditions, including heavy rain and snow. They come in various colors and sizes, allowing for customization in design. However, slate roofs can be more expensive to install compared to other roofing materials, such as asphalt shingles.
