Tiling a roof

One of the most common and popular roofing materials, roof tiles are available in a wide range of sizes, and when installed correctly, they provide a long lasting and weathertight roof covering to keep your home or building protected.

Here at Roofing Superstore we have a wide range of roof tiles and slates to find out But how do you tile a roof in order to ensure maximum durability and an attractive finish? Read on to find out everything you need about tiling a roof.


Choosing the roof tile material

Before tiling a roof, it is important to identify which type of roof tile you’re going to be using on your roof.

Clay roof tiles

Clay roof tiles are incredibly popular and have been used for hundreds of years. Not only do they allow you to create a traditional and timeless roof, they are one of the longest lasting roofing materials available. Additionally, clay tiles are relatively consistent in colour and size, meaning the appearance of the overall roof is consistent and clean.

Slate roof tiles

Slate roof tiles are another popular roofing material. Slate roof tiles are popular due to their naturally stunning appearance, which creates a crisp and clean finish, as well as having natural variations in colour running through. Slate roofs often have a lifespan of 100 years of more, making them incredibly long lasting and great for traditional buildings.

Concrete roof tiles

Concrete roof tiles have increased in popularity as techniques have developed to provide an incredibly wide range of colours, sizes and styles of roof tile. Concrete roof tiles are often used on projects where environmental credentials are considered, as concrete roof tiles are relatively environmentally friendly.

Plastic roof tiles

There are also a number of plastic roof tiles that have been manufactured from recycled plastic to create a lightweight and environmentally friendly alternatively. Plastic roof tiles come in a number of different styles, colours and sizes, so it is possible to emulate the look of a more traditional roof, but with more environmentally friendly credentials.


Calculate the number of roof tiles required

Calculate roof area

Once you’ve chosen the roof tiles you want to install on your roof, you need to calculate how many roof tiles you’ll need. To do so you’ll need to know the size of one roof tile, and the size of the roof area. For more information on how to calculate the roof area, click here.

Calculate number of tiles required

Once you’ve worked out the roof area, you can divide it by the size of a roof tile. Alternatively, take a look at the manufacturer’s guidelines – manufacturer’s generally provide a figure detailing how many tiles are required per metre squared of roof. Check out our guide for more details on calculating how many roof tiles you need.


Ensure you have everything you need

Once you’ve calculated the number of tiles you require, and have all other necessary tools and equipment, tiling the roof can begin. Don’t forget, as well as regular tools and accessories such as a ladder and a hammer, you’ll also need the roof tiles (including ridge and hip tiles where necessary), roofing nails, timber battens, underlay and sealant.


Prepare the roof

If working on a pre-existing roof, the first step is to remove any existing roofing materials. Additionally, take a look at the sheathing – if any of it is damaged, replace or repair it. It is important to have secure sheathing as this will be supporting the roof tiles.


Install underlay

Once the sheathing has been checked and replaced where required, the underlay can be installed. The underlay should be rolled out parallel from the bottom eaves, working up to the top of the roof line in sheets, overlapping the top of the roof before securing on the other side. Ensure there is an overlap between each roll of underlay in order to create a seal, and nail the underlay to the sheathing, ensuring the nails are spaced at around 50cm apart.


Fit timber battens

Once the underlay has been installed, timber battens need to be fitted to provide a stable surface on which to attach the roof tiles. The space between timber battens is calculated using the tiles – Tiles should always have a minimum of 3 inches of overlap, apart from at the eaves where the eaves tile should reach the centre of the gutter.

Therefore, place a tile on a timber batten, and another tile on a timber batten below. Move the battens together or apart until an overlap of 3 inches occurs between the two tiles. Then measure the distance between the two battens – this is the distance that should be between each timber batten. Start with a batten at the bottom of the roof, and ensure a tile will extend to the centre of the gutter, and then work your way upwards, installing battens with the calculated distance between them.


Tile the roof

Now the tiles can be installed. When putting the tiles on the roof during installation, ensure they are evenly spread across the whole roof to distribute the weight evenly. You should generally work from right to left, and if there are any obstacles such as chimneys, work around them before coming back to them later. When starting at the eaves, the tiles should extend so that they reach the centre line of the gutter.

Cut tiles where required

In some circumstances, tiles will need to be cut in order to fit into smaller sizes or complete a row. If this is the case, you should never cut a tile that is smaller than half the width of a regular tile, and should never cut the tile on the bottom edge.

Install ridge tiles

Once the regular tiles have been installed, the ridge tiles can be fitted at the top of the roof. Ridge tiles can be overlapped or installed end to end, depending on the type of ridge tile you have.
