Slate roof installation is usually done by professionals as it requires special skills and knowledge. However, there are some DIY enthusiasts who like to do it all by themselves. If you are one of them you will want to acquire some fundamental skills and knowledge so as to ensure that you do not make the elementary mistakes. Here are some of the things you will want to know as a starter before installing the slate roofing in Melbourne or for that matter anywhere else.

Basic Practices

While you are installing the slates, make sure that you do not walk on them. You are going to need a scaffold or a roof ladder. This makes sure that the slates do not slip off after the installation. It is also important to mark the courses of the slate on the roof surface. The slates are then laid along these marks. But make sure that you do not create a mark on the slate itself. Take proper measurements to make sure that the slates are being installed consistently and accurately. Marking using chalk is critical to ensure proper installation.

Getting the starter course right

Whether you are installing Spanish slate roofing in Melbourne or heritage slate roofing in Melbourne it is extremely important to get the starter course right. You are going to need a shim or a wooden cant. The wedge will be nailed to the bottom of the starter course. This is an important step as it brings the starter course at the same angle as the other slates by tilting it. The face of the slate must be towards the roof surface and the back should be facing up during installation. Remember that it is only the starter course that needs to be laid in this manner. With other slates, the beveled edges will be exposed as they will be installed with the face up.


Side and head laps  

It is also important to make sure that the side laps are created correctly. There will be an overlap between the first course and the side butts of the starter course. These laps on the side must be a minimum of 8-10 cm.

Each slate also has to overlap the minimum of two courses below it. At the same time, it is important to make sure that the head lap is installed correctly. This has to be done to ensure that the roof does not allow any water to seep in and remains watertight. If it is not installed properly then it will leak.

Remember that the underlays, as the name suggests, have to go under the slates. They should not be placed on the top of the slates.


This is also one of the most critical aspects of the slate installation. You have to be careful as incorrect technique can damage the slates. Do not drive the nails beyond the specified point otherwise they will apply pressure on the overlaying slates and cause damage.
