Australia’s Expert Slate Roofers

Slate Roofing Merchants have provided slate roof restorations for some of Australia’s most historic and culturally important buildings. We have decades of experience and can guarantee a quality slate fix to your modern or historic home, church or historic building. While quality slate is important, an experienced ‘slater’ or slate ‘fixer’ is imperative to getting the result you deserve when using slate. Slating is a craft that is learned through many years if not decades of experience.

Installation Recommendations


This is the most important consideration with any form of roofing. As with interlocking tiles, slates must NEVER be fixed on a roof with less than 75mm headlap. Any slate roof fixing system with less than 75mm headlap should be rejected. Some exposed positions or roofs with flatter pitches may require a larger headlap.


Always use a softwood batten due to slate nailing considerations.


A nail with a clout like head can be used to fix slates provided that the slate is punched and not drilled as the punching from the back gives a countersink on the face of the slate for the nail head. As an alternative a stainless steel hook system can be used.

Laying Slates

Slates should be laid with a broken bond and secured with nails or hooks to softwood battens. Before fixing, perpendicular lines should be marked giving the correct bond and spacing, Approximately 4mm should be left between the vertical joints of each slate so that is a free thoroughfare for water running down the roof. Slate should be started  from the eaves and fixed diagonally across and up the roof slope.
