Concrete vs Clay tiles

[akist]

As we cannot find the clay tiles we want, 21 weeks lead time, we are looking at concrete tiles which they have in stock. I presume both concrete and clay tiles are the same when it comes to longevity and problems?

Concrete can last longer than some.
Which clay tile had you in mind?

Due to roof being 22° and dormers being 18°, we are limited to a handful of clay tiles, namely Sandtoft 20/20 Interlocking which is my preferred choice. Unfortunately, none out there.

For concrete tiles there is a bit more choice currently looking at

or

BMI Redland Mini Stonewold https://redland.co.uk/products/slate-range/mini-stonewold

PS: from what it is already in stock here and there.
