Slate roof

Slate roofing is a very popular roofing for its traditional aspect and its charm. It is made of a material from the shale family. Purists particularly appreciate its dark gray hue and its reflections in shades of blue. It is a siding that definitely adds character to a residential building.

The different types of slate

Natural slate

This material comes from a quarry. More precisely, it is a metamorphic rock that has been transformed under the effect of pressure and temperature. Such conditions have caused the appearance of crystals. Slate roofing can last up to 100 years.

Synthetic slate

This material is made from a specific mixture of organic fibers, water, minerals and cement. Its design has been specially thought to give it similar qualities to the natural version in terms of resistance and insulation. However, synthetic slate is less durable.

In both cases, slate roofing is quite expensive, although very durable. Therefore, this material is not commonly found on commercial, industrial or institutional buildings.

Install, repair and maintain a slate roof


Regarding the installation of a slate roof, it should be noted that this coating is not compatible with a flat roof or rounded shape. In addition, the frame must be very strong to support the siding.

The installation is generally done with the hook method, when the installation is done on the laths. This technique is the most popular, as it ensures the stability of the assembly even in strong winds.


Slate has the advantage of being maintenance-free for the first 20 to 30 years after installation. Afterwards, it is necessary to clean the roof.

At Toiture Couvreur Saint-Sauveur, we can take care of this maintenance. We use adapted products to avoid the proliferation of moss and fungi. Our technicians also have all the necessary equipment at their disposal in an efficient and safe manner.


If maintenance is not enough, you should consider repairing or even replacing the slates. In this case, it will be necessary to either replace flashing strips or replace defective or missing slates.
