Natural Slate
When it comes to longevity few roofing materials can compete with natural slate. A slate roof could easily last 25-100 years max, which is at least double of what other roofing materials can offer.
For people who do not plan to ever sell their home, the incredible longevity of natural slate is a highly desirable benefit.
