It might have never crossed your mind, but when building or renovating a roof, size matters for the slates you want to use. Let’s compare two Cedral slate sizes: 400x220mm and 600x300mm. So how do you choose between them? You’ll find out in this article.
Bigger or smaller, that’s the question. Here are a few elements to consider that will guide you in your choice of slate size.
This is one of the more traditional slate sizes. They have the advantage that their overlap makes them more weatherproof. This slate size works well with many roof features, such as hips, valleys and dormers. They can only be used with roof pitches of 30° and above.
One of the examples in the Cedral range is the Kergoat fibre-cement slate. These are traditional slates with riven edges and a finely detailed surface. They have a regular thickness so you don’t need to do any sorting onsite, making installation fast and economical. These fibre-cement slates are unaffected by frost, rot and fire and come with a 15 year warranty.

The 600x300mm slates are bigger than average. This allows you to create a more luxurious and modern look for your home. They are particularly recommended for bigger roof surfaces. The bigger size allows for even more overlap so that they have excellent rain-proof qualities. On the downside, the bigger the slate size, the more expensive they tend to be.
The Thrutone slate is one of Cedral’s 600x300 slates. This low-profile slate has a smooth surface and square cut edges, particularly suitable to complex roof geometries. This lightweight fibre-cement roof slate is available in six colours. With its low wastage and ease of installation, it is one of the most economical options in its category.
