Choosing between tiles and slate is one of the first decisions when planning a new roof. Both are long-lasting and both are common across South Wales, so the right choice usually comes down to the style of the house, the structure underneath and how it looks next to its neighbours.
Appearance and the street
Slate has a fine, slim, even finish that suits older terraces and villas, and many South Wales streets were built with it. Tiles, whether concrete or clay, give a bolder, more textured look and are common on post-war and modern houses. If your home sits in a row where every roof is slate, a different covering can stand out, so it is worth looking at what your neighbours have and whether any local rules apply.
Weight and the structure
Tiles are generally heavier than slate, particularly concrete tiles. Before changing from one covering to another, the roof timbers need checking to be sure they will carry the new weight. Going from a heavy tile to slate is rarely an issue, but the other way round needs checking first. We look at the rafters and the way the roof is built before recommending anything.
Maintenance and repairs
Both coverings are durable when properly fixed. Slates can slip when old nails corrode, and tiles can crack or lose their pointing at the ridge, but individual pieces can be replaced in either case. The underlay, battens and flashings beneath tend to need attention before the covering itself does, which is a good reason to renew the whole roof build-up at the same time rather than just re-laying the top layer.
Which should you choose?
If your house already has a slate roof in sound condition, slate is usually the natural choice. If it has tiles and you want a straightforward like-for-like renewal, tiles are the simple option. It is a fair question to ask for both options in a quotation, so you can compare the look and the cost.
