How To Choose Roof Slates In Sydney
Roofing slates are one of the most durable roofing materials available. A well-installed roof can last over a century depending on the quality of materials used. In many cases, the roof will outlast the building it covers.

Categories and sizes
Roofing Slates used to be categorized by quality. In descending order of quality, these are bests, seconds, thirds, and tons. The majority of builders and roofing merchants will now categorize the materials by size and origin.
The sizes range from 24 inches by 14 inches down to 10 inches by 16 inches. Generally speaking, the larger sizes are used on bigger builds or to provide increased coverage towards the bottom of the roof.
When building a new roof, consideration should be given to the local climate. Due to the way water travels over a roof slate, (the angle of creep) larger sizes are more suitable for wetter climates.
