What Is a Slate & Half?
A slate-and-half is a wider roofing slate used alongside standard-sized slates where additional width is required within a roof layout.
With dimensions of 500x375mm, this Sumo Slate & Half is one and a half times the nominal width of the matching 500x250mm roofing slate.
The wider format allows roofers to maintain an appropriate bond and fixing arrangement around certain roof details without creating excessively narrow cut slates.
Designed to Match 500x250mm Sumo Slate
This Slate & Half is designed to be used with the matching Spanish Sumo Best Quality Natural Slate Roof Tile 500x250mm.
Using matching Sumo slate helps maintain a coordinated dark blue-grey colour and light riven surface across both the main roof covering and the detailed areas where wider slates are required.
Ideal for Verges & Gable Ends
Slate-and-half units are commonly used at roof verges and gable ends where additional width can be required to maintain the correct bond and provide secure slate fixing.
Using a wider purpose-sized slate can help avoid narrow cut pieces at the roof edge and provide a cleaner, more professional roofing detail.
Suitable for Hips & Valleys
The wider 500x375mm format is also useful when working around hips and valleys, where the roof geometry often requires additional slate width before pieces are cut to suit the roof detail.
Always follow the project specification and appropriate slating practice when setting out and cutting natural roofing slate around hips and valleys.
Slate & Half for Roof Windows
Slate-and-half roof tiles are commonly used around roof windows and similar penetrations where the normal slate layout is interrupted.
The additional width can help maintain the slate bond and fixing arrangement around the window while reducing the need for narrow pieces of cut slate.
Natural Spanish Sumo Slate
Sumo is a natural Spanish roofing slate from the Yates range, quarried in the Zamora region of Spain. It is characterised by a dark blue-grey colour and a light riven surface.
As a genuine natural stone product, individual slate-and-half pieces can show subtle variations in colour, texture and surface character. This variation is normal and forms part of the appearance of a natural slate roof.
Consistent & Workable Sumo Slate
Yates describes its Sumo slate range as renowned for its even thickness and ease of cutting, characteristics that make it popular with professional roofing contractors.
Good workability is particularly useful with slate-and-half pieces because these wider slates are frequently required around detailed roof areas where additional cutting and shaping may be needed.
W1, T1 & S1 Performance Classification
The Yates Sumo range is stated as compliant with BS EN 12326-1:2004 and classified as W1, T1 and S1.
- W1: Water absorption classification
- T1: Thermal cycle classification
- S1: Sulphur dioxide exposure classification
These classifications form part of the performance assessment used for natural roofing slate.
75-Year Quarry Guarantee
The Yates Sumo range carries a 75-year quarry guarantee, providing additional reassurance when specifying Sumo natural slate for long-term roofing applications.
The quarry guarantee should be considered alongside correct product selection, handling and installation in accordance with the roof specification.

Installation Advice
Natural slate roof tiles should be installed in accordance with the project specification, relevant roofing standards and good slating practice.
The required gauge, headlap, fixing arrangement and positioning of slate-and-half units will depend on the roof design, pitch and exposure.
Use suitable slate fixings, such as appropriate copper roofing nails or slate hooks where specified, together with correctly specified roofing membrane and BS 5534 graded roofing battens where required.
Natural Slate Variation
Natural slate will vary slightly in colour, surface texture and appearance from piece to piece. Slate & Half units should be selected and graded alongside the standard Sumo slates during installation to achieve a balanced appearance across the completed roof.
