Calidad Natural Roof Slate
Calidad slate from across Spain – including the La Bana region – is an excellent roofing slate, with an excellent finish and slightly textured appearance. This type of roofing slate is especially suited to projects which require the highest quality, but which also need a more complex final result. The selection process and pass criteria for Calidad slate is very stringent, with only the highest quality slates making the grade. Because of this, you can be sure that it will give an excellent finish to your project when fitted in accordance with BS5534. The Calidad slate we have comes in a range of specifications, from Calidad 10 through to Calidad 120 roofing slate. All of these slates have achieved the highest possible classification when tested to BS EN 12326.
