One of the best ways to increase the longevity of your roof is to use clay or concrete tiles. Apart from being durable, they are lightweight, and provide the best insulation compared to corrugated iron sheets, for example.
The roof tiles installation process starts with picking the correct size, colour, and method of installation. In this write-up, we shall address how to install a tiled roof in Pretoria. However, this is largely dependent on the type of material the tiles are made of.
The Right Slope For Clay Or Concrete Tiles
Roof tiles are perfect for new roofs with slopes of at least 20 degrees. The more the slope, the more the aesthetic look for the house. That’s why you are most likely to spot clay and concrete tiles on the steeping roofs of cathedrals. Before you lay tiles in place, you have to ensure that you have a level surface. If you don’t, you can level it up by applying some mortar or some appropriate product.
Roofing Underlayment For Clay Or Concrete Tiles
It is important to learn how to install tile roof underlayment before you even stay to install the tiles themselves. The materials you choose for the underlayment will play a very key role in determining how durable the tiles will be.
In most cases, the underlayment is made of an asphalt-based material. It covers the area under the tiles. If it is not properly installed, you will end up having to contend with overlying tiles too soon. Add an extra layer close to the roof’s edge and in the valleys to give extra protection to the surface.

Roof Tiles Installation Process
Once the underlayment is in place, then it is time to start the roof tiles installation process. The first thing you will install is the tile roof flashing close to the vents, conduits, chimneys, and the meeting points of the roofs and vertical walls. You need to use a 28-gauge tile roof flashing. Here is how to install a tiled roof in Pretoria:
Step 1. Clay tiles should laid such that the first on the batten and its crown facing up. The centre should spread from side-to-side. This is when you have to start nailing roof tiles by driving a 10d nail at the tile’s base right into the batten. Over-driving the nail is a no-no.
Step 2. To support the tile some more, add some mortar under the first tile. Install another one on top of the inner end of the first tile. After measuring the outer end, adjust the new tile appropriately.
Step 3. After nailing the second tile, place two additional tiles to the opposite ends of the ridge and repeat the installation process.
Step 4. To know the number of tiles you need to install, measure the distance along the ridge from outer ends of the first tiles installed at opposite ends of the ridge. After subtracting 16 inches, divide the answer by 8 to know the number of tiles you should install.
Step 5. Start installing the tiles from one end to the centre and then go to the other side. Lay the tiles and finish off by installing a key tile at the centre using mortar.
