A low cost charcoal/grey slate that is uniform in thickness, texture and appearance. A feature of this particular slate is its tendency to naturally weather relatively quickly, thereby creating the appearance of a more established, mature and naturally aged roof that blends well with existing roofs in the surrounding area. Unlike second hand slates it comes with a performance warranty and is the ideal choice where low price is the main criteria.

One of the unique and aesthetic advantages of natural roofing slate is the subtle variation in colour, shade, veining, and grain of each individual slate on a roof. Similarly the thickness of slates in each crate may not be exactly the same. These variations should be expected. All slates weather naturally over a period of time once installed and a feature of Chinese slates in particular, is a tendency to weather and show various percentages of colour change more quickly; thereby creating the appearance of a more established and naturally aged roof. Weathering will not affect the slates functionality.
