Composite Slate Roofing

Composite Slate Roofing offers the benefits of slate without the many shortcomings. Unlike quarried slate, which usually requires an engineered roof framing system (structural support) because of its weight, Composite Slate Roofing has the aesthetic appeal of slate roofing without the enormous weight. Composite Slate is cast from real slate roofing and the variety of solid and multi colours replicate quarried slate, providing a classic, architectural realistic appearance.
