How To Choose Roof Slates In Sydney

  • October 18, 2021

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.

When the roofs eventually need replacing then it will more than likely be due to the corrosion of the nails. The roof covering will often be reused. However, you can also choose Leading Penrhyn Welsh Slate Supplier & get FREE Quotes online.

It is due to this durability that roof slate can be considered truly "green" or environmentally friendly. Other roof coverings may have to be replaced many times in the life of a similar slate roof increasing carbon emissions.

The material is formed when rock is forced into thin sheets by intense pressure. In the past slate produced in Australia came from five main areas.

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.
