Hardrow duet roof slates are suitable for use in regions where a natural stone slate appearance is required. Our concrete roof slates combine two subtle blends of colour on each tile to provide 10 regional effects.

Hardrow duet slates are extremely durable and mellow with age. They are suitable for use on contemporary or conservation projects, new builds and renovations. The slates are manufactured with a slight camber and variation in dimensional tolerance. This adds to the product's charm when laid.

Benefits

• Cost effective alternative to natural slates.
• Provides a quality finish at a modest cost.

Fixings

• For pitches below 40° it is possible to hang the slates, depending on conditions, but advice can be sought from the roofing superstore team.
• Above 40° all slates should be nailed into the batten with 2 x 38mm x 3.35mm aluminium nails (40mm x 4mm for 24 x 18 slates).
• The nail hole diameters are approximately 5mm with the nail holes being approximately 50mm down from the heads of the slates and 50 - 100mm in from the side edges.
