Slate roofing is often considered the best and most expensive type of roofing. Slate roofing is quarried from rock, made to resemble shingles. It gives more upscale homes a natural, distinctive look. It is fireproof, low-maintenance, and long-lasting. A slate roof may last 75 to 150 years, or even longer. Like clay tile, slate is heavy and fragile, so ask Peachtree Roofing if slate is the right choice for your home.
