Slating Manual

The Tegral Slating Manual is divided below into five sections for ease of use. These are structured to follow the normal sequence of slating design and construction.

1. Design for Slating

This section of the manual contains an outline of the design principles involved and other useful guidance that applies to all slated roofs.
Armed with this information, the designer will be in a position to determine the exposure rating of a site and decide what category the roof falls into – whether it is a “standard”, “non-standard” or “special” roof.

2. Standard Roofs

Roofs falling into this category have the following characteristics:
Any roof slope equal to or greater than the minimum pitch for the size of slate preferred that has a rafter length (horizontal projection – ie, measured on plan, not along the slope, from ridge to eaves) not exceeding 6 metres. This section looks at the different principle parts of a roof as follows; The Eaves, The Verge, The Ridge, The Hip, The Valley, Abutments, Change of Pitch, Roof Windows

3. Non Standard Roofs

Roofs falling into this category have the following characteristics:
(a) any roof slope equal to or greater than the minimum pitch for the size of slate preferred that has a rafter length (horizontal projection – ie,
measured on plan, not along the slope, from ridge to eaves) between 6 metres and 9 metres.
(b) any roof slope less than, but not more than 5º less than, the minimum pitch for the size of slate preferred that has a rafter length (horizontal
projection – ie, measured on plan, not along the slope, from ridge to eaves) not exceeding 6 metres.

4. Special Roofs and Vertical Slating

Roofs falling into the category of "special" roofs have the following characteristics:
(a) any roof slope equal to or greater than the minimum pitch for the size of slate preferred that has a rafter length (horizontal projection – ie,
measured on plan, not along the slope, from ridge to eaves) greater than 9 metres.
(b) any roof slope less than, but not more than 5º less than, the minimum pitch for the size of slate preferred that has a rafter length (horizontal
projection – ie, measured on plan, not along the slope, from ridge to eaves) greater than 6 metres.
(c) any roof slope between 5° and 7° less than the minimum pitch for the size of slate preferred that has a rafter length (horizontal projection –
ie, measured on plan, not along the slope, from ridge to eaves) not exceeding 6 metres.
(d) any curved roof, including turrets and spires.
(e) traditional "open slating" or single-lap slating, such as diamond slating or "German" slating, etc.

5. Specifications and Site Work

This section looks at a series of specification clauses, covering both general and detailed aspects of materials and workmanship. This model
specification is recommended when specifying Tegral slates and accessories. It can be added to or adapted to accommodate most types of
construction. For more specification information email support@tegral.com
