Slate shingles are divided into two categories: hard and soft. They come in various sizes, shapes, colors, and styles. Colored slates are most of the time classified as hard slate and black slates are most commonly soft, but of course, there are some exceptions. Sometimes a colored slate faded due to sun exposure and becomes black.Hard slate is one of the toughest kinds of roofing available, it holds the structure for decades and has some properties that increase its durabilities. Hard slate doesn’t absorb water or become distorted from exposure to moisture and has high weather resilience and fire resistance. Due to these characteristics, shingles made from hard slate can last anywhere from 75 to 200 years.
Soft slate is the less enduring of the two. Its overall structure doesn’t have resistance from the Hard slate. That’s why shingles made of soft slate usually have a life prospect of 50 to 125 years. However, soft slate has the equivalent weather-resistant and fireproof features when compared with hard slate.
