Whether you’re restoring a historic property or building something new, this guide will help you choose clay roof tiles that work for your design and environment.

The 7 Types of Clay Roof Tiles

If you’re planning a clay roof replacement or starting a new roofing project, understanding the different types of clay roof tiles available can help you make the right choice. From classic plain tiles to bold barrel styles, each option offers its own aesthetic and functional benefits of a clay tile roof.

1. Plain Clay Tiles

Also known as clay plain tiles, these are small format, flat tiles laid in neat rows with a double-lap installation method. They’re one of the most traditional clay roof tiles, often used in restoration projects or where a heritage aesthetic is important. The timeless, understated look is ideal for listed or heritage buildings and properties within conservation areas.

Key features:

• Small rectangular shape
• Laid in overlapping rows for extra weather protection
• Typically installed with a minimum roof pitch of 35 degrees

Plain tile roofs have a high density of tile overlaps, providing superior protection against rain and wind. They are particularly well-suited to harsh weather conditions in the UK and require little maintenance once installed properly.

2. Interlocking Clay Roof Tiles

Interlocking clay tiles are designed specifically to make installation faster and more efficient. Instead of overlapping like plain tiles, they slot together using channels or grooves that lock them in place. This style means fewer tiles per square metre, which can reduce costs and labour time.

Key features:

• Larger format
• Single lap installation
• Often have high profile ridges for strong water runoff

Interlocking tiles are available in various types, including flat and curved designs. They’re commonly used in new builds where time and cost efficiency are priorities, but still offer the traditional look of natural clay.

3. Roman Clay Tiles (Including Double Roman)

The Roman clay tile is a nod to classical antiquity, designed with alternating flat and curved sections to guide water off the roof effectively. Double Roman tiles feature a more pronounced curve, giving them a bold, undulating pattern across the roofline.

Key features:

• Flat pan with raised roll sections
• Low minimum roof pitch (usually 17.5 degrees or more)
• Ideal for Mediterranean-style or picturesque Roman roofs

These tiles provide excellent water drainage and can handle high rainfall without compromising performance. Their distinctive appearance suits both traditional and modern buildings looking for a roof with strong visual character.

4. Barrel Style Tiles / Mission Tiles

Barrel style tiles, also known as mission tiles, are semi-cylindrical and typically laid in alternating concave and convex rows. This style originated from regions with hot, dry climates, but is now used globally for its distinctive, rustic charm.

Key features:

• Curved, cylindrical profile
• Traditionally installed using mortar or mechanical fastenings
• Offers a high level of airflow and heat deflection

Mission tiles can be more labour-intensive to install and may require special fixings to fasten clay roof tiles securely. However, the result is a visually striking roof with excellent performance in both dry and wet climates.

5. French Clay Tiles

French tiles combine interlocking technology with classical styling. They often feature a pronounced curve and deep side channels that provide excellent waterproofing.

Key features:

• Interlocking mechanism
• Suitable for roof pitches as low as 22 degrees
• Elegant profile, great for both rustic and urban styles

These tiles are popular in areas of Europe but have become a favoured option in the UK for homeowners seeking high quality, aesthetically pleasing roofing materials that blend modern functionality with a traditional look.

6. Flat Clay Tiles

Flat clay roof tiles offer a sleek and minimal aesthetic, making them a great fit for modern homes or renovations aiming for clean lines. These can come as plain tiles or interlocking varieties, and are available in a wide range of colours and finishes.

Key features:

• Smooth, low-profile appearance
• Various colours and finishes
• Versatile for different roof shapes

Because of their simple shape, flat clay tiles are one of the most adaptable styles. They’re often chosen for their ability to fit in with different architectural styles, and are popular among designers who want a modern edge without sacrificing traditional clay durability.

7. Decorative or Ornamental Clay Tiles

While not a separate structural type, ornamental tiles add unique characteristics to clay tile roofs. These can include crested ridge tiles, finials, or specially-shaped tiles placed at gable ends or around chimneys.

Key features:

• Designed for visual appeal
• Often used on heritage or bespoke builds
• Can be combined with standard tile types

Decorative clay tiles are a great way to add personality or historical detail to a roof, particularly on listed buildings or projects where authenticity and craftsmanship are important.

Comparing Clay vs Concrete Roof Tiles

When choosing between clay and concrete roof tiles, it’s useful to understand the trade-offs. Concrete tiles tend to be heavier and absorb more moisture than clay, which can reduce their lifespan. Clay tiles are fired at higher temperatures and have a denser, more durable structure. They’re also colourfast, meaning their appearance doesn’t fade over time like some concrete roof tiles.

That said, concrete options are often cheaper and available in more styles, which may appeal to homeowners on a tighter budget. However, if you’re looking for higher quality, distinctive clay roof tiles are usually the better long-term investment.

Choosing the Right Clay Roof Tile

There’s no one-size-fits-all answer when it comes to the best clay roof tile. Your choice should be guided by factors like:

• The style of your property
• Your roof’s pitch and structural load-bearing capacity
• Your budget and maintenance preferences
• Local climate and exposure to harsh weather conditions
• The condition of your roof (how long a clay tile roof can last)

Make sure your roof design meets the lowest angle or minimum roof pitch for the tile type you select. For example, plain tiles need a steeper pitch than interlocking clay tiles. Also consider colour and texture. Clay roof tiles are available in everything from deep reds to pale ochres, with smooth or sanded finishes depending on the particular type and brand.

Final Thoughts

Clay tiles are more than just a roofing material. They offer a combination of durability, traditional look, and low maintenance that makes them a sound investment for many building types. Whether you’re after the classical lines of barrel style tiles, the practical benefits of interlocking clay, or the refined simplicity of clay plain tiles, there’s a style suited to your project.
