The Stoneleaf SL11 Natural Slate

Stoneleaf SL11 natural roof slate is extremely flat with a smooth even texture. The SL11 is a fine choice for both period properties and modern homes guaranteed to enhance the individual character of any building.
Natural slate is a great choice for homeowners who are looking for a beautiful, durable, and low-maintenance roofing material.

The SL11 are graded and suppiled into 2 thicknesses, 5mm and 6mm. This additional sorting process means they require very little on site sorting, making them more economical to lay as less need to be rejected or wasted. 

Case Study - Writtle Renovation

The Stoneleaf SL11 fitted the bill for this renovation project in Writtle. The developer was looking for a slate that wouldn't break the bank but still lays flat, is easy to sort and isn't fragile like glass (like many cheaper slates can be). The varying shades of colour in the SL11 adds to the character of this property with its decorative brickwork and chimneys.
