A Guide to Concrete Roofing Tiles
30th January 2018
Concrete tiles have become the dominant choice of material in the modern roof tile market. Their adaptability and lower costs tick two crucial boxes for developers and property owners alike. Our concrete roof tile guide gives you all the starter information you need. Our intention is to set you on the right track to selecting concrete tiles that will enhance the value your home. Read on to learn about the potential costs and advantages of using concrete roof tiles.
Advantages of Concrete Roof Tiles
Although concrete roof tiles have been around for almost a hundred years, their usage has increased significantly over the past 50 years. They are now the most widely used on the market and have the ability to mimic the shape and colour of clay tiles. They're also easier to fit and more cost-effective. This made them popular with developers in the post-WWII housing development boom, as Britain began to rebuild its infrastructure.

The mixture of cement, sand and water, along with a number of smaller aggregates added by manufacturers, gives the material a great advantage in terms of its adaptable nature. Concrete roof tiles can be moulded to match almost any design style and the range of colours available is almost unlimited.
With three profile appearances to choose from – flat, low or high profile – concrete tiles can be installed across every type of roof pitch. In addition, the texture can either be rough or smooth depending on the requirements of the architectural design they are being used for.
How Long Do Concrete Roof Tiles Last?
Aside from their cost-effectiveness, one of the main reasons why concrete tiles have become so popular is their durability. Therefore, manufacturer warranties will typically last for 30 years but concrete tiles should last up to 50-60 years at a minimum and even longer in a number of cases.
As with any roof tile, the lifespan will depend on how well maintained the roof space is over time. You also need to consider the general environment of the surrounding area. In regions where extreme weather conditions are the norm, this will be taken into consideration during the build. Concrete tiles are manufactured to protect the building from standard levels of wind and rain. However, any cracks or breakages will need to be addressed quickly to prevent further issues being created within the structure.
How Much Do Concrete Roof Tiles Weigh?
Due to the materials that go into making concrete tiles – cement, sand and water – they are considerably heavier than clay tiles. The weight will vary depending on the manufacturer but concrete tiles generally weigh upwards of 70kg per m².

When homeowners or developers are weighing up the pros and cons of tile types, further consideration should be given to the supporting structure underneath. This is especially true when choosing to use concrete tiles. This is because concrete has a higher rate of water absorption so heavy rainfall will add to the overall weight of the structure.
What is the Minimum Roof Pitch for Concrete Tiles?
The manufacturer will supply all the technical information regarding the pitch of the concrete tile you have purchased. However, paying attention to this is absolutely crucial as laying a roof below the recommended minimum pitch is likely to lead to the underlay being exposed to rain and water which could lead to costly repairs being needed in the long run.
As a general rule, 15° is the minimum pitch for concrete tiles which has decreased from the original recommended level of 20°. Additionally, there are some concrete tiles available that can be laid as low as 10° although these are not too commonly used.
For example, the Marley Wessex Concrete tile offers great flexibility as a demonstration of a low pitch roof tile. This popular option can be used on roofs as low as 15°, and because it is specifically designed to shed water efficiently from its surface, it is a good choice for a low pitched roof.
How Much Do Concrete Roof Tiles Cost?
This section is intended to provide you with an idea of the level of pricing for concrete roof tiles which can range from approx: £0.40 per tile to upwards of £100 for more specialised products.

While there are a number of reasons why concrete has become the dominant material on the market, the price is probably the number one factor. This is especially true for developers when building a host of new properties. This is because they need to work with materials that tick a number of boxes, with budget usually deciding many of the choices made. As a result, homeowners thinking of re-tiling to increase the value of their home will mostly opt for concrete to match their own spending limits.

Concrete roof tiles can be anywhere up to 50% cheaper than clay tiles. Although, this depends on which type they are being compared against. This means that concrete tiles will be far cheaper than man-made clay tiles, while also being around 10% cheaper than machine-made clay tiles.
If you are not an experienced tile installer then costs can quickly add up. Saving money by purchasing lower value concrete tiles and not using a professional company to install them may save you money in the first instance. However, without the relevant experience, it is easy to run into problems that can quickly add to the overall cost and could end up being far more expensive in the long run.
Concrete Tile Price Examples
For those on a budget, the Marley Plain Concrete tile is a very reasonable product and is available with either a smooth or granular finish and are made very much in the classic mould. If you're looking at the more expensive end of the scale, you will find concrete tiles such as the Marley Wessex Concrete tile which can be laid as low as 15°. You will usually find that concrete low pitched tiles are more expensive due to the research and development that is needed in their design.
