What is an Interlocking Roof Tile?

Maguire Brothers look at what an interlocking tile is, and what advantages they bring to our clients.

Over the decades, the teams at Maguire Brothers have been advising clients on what tiles or slates are most appropriate for their roofing projects.

While numerous factors need to be taken into consideration when proposing the suitability of a tile, on the basis an interlocking tile is chosen, we thought we’d dive a little deeper into what an interlocking tile is, the benefits of interlocking roof tiles and the different types of interlocking tiles.

What Are Interlocking Roofing Tiles?

Interlocking roofing tiles are tiles designed to interlock with each other, making them economic to manufacture and simple to install which reduces labour costs during installation.

Interlocking tiles incorporate a connecting mechanism that joins one another across the roof. Modern manufacturing techniques have allowed for traditional designs to be replicated with this interlocking technology.

Where one tile is joined to the next, a drainage channel is created allowing any water run-off to discharge onto the course below, therefore not penetrating the system. Interlocking tiles are suitable for use on lower pitched roof elevations.

The three main types of interlocking tiles are:

  • Plain Interlocking Roof Tiles
  • Clay Interlocking Roof Tiles
  • Concrete Interlocking Roof Tile

Interlocking tiles can be laid in a single lap pattern which is quicker and more efficient to install, or a broken bond pattern which enhances the strength of the roof and is more suitable on lower pitches.

Like with all roof coverings, there are a great variety of design options. Interlocking roof tiles can be smooth, granular, flat or profiled. Interlocking tiles are also more environmentally friendly due to their sustainable levels of production.

The two main reasons for the popularity of interlocking roofing tiles are suitability and cost.


Interlocking roof tiles are designed to replicate other more traditional roof coverings, however many of these coverings are not suited to low pitched roof areas. Interlocking tiles on the other hand can be installed in some cases to pitches as low as 10°.


Interlocking roof tiles have a much greater coverage rate resulting in far fewer tiles used per m². Additionally they are relatively simple and quick to install, saving on labour costs. You will notice that many house builders will opt for interlocking roof tiles for these reasons.


Interlocking roof tiles are a very cost-effective roofing option. The speed and ease of installation cuts down on the length of the project. There are also lots of options when it comes to the looks of the tiles for instance, by using a broken bond pattern they can mimic roof slates which a lot of clients prefer. Interlocking roof tiles combine modern techniques with traditional designs to create a versatile product that saves time, money and the environment.
