FAQ's

What is roofing slate

Slate is a fine-grained, foliated and homogeneous metamorphic rock. It is sourced from a natural kind of sedimentary shale rock. The rock consists of a combination of clay and volcanic ash. It is one of the most durable types of roofing material.

Does roofing slate just come in slate grey or are there other options?

Slates come in a wide range of colors, from grey, black, green, purple and many more, if you are interested in sourcing a more unique colour, please contact us to discuss our variety.

Can I choose any size of slate for my roof

The size of slate is largely dictated by the pitch of your roof. The shallower the pitch the fewer the options, also the geographical location of the project can also determine the size of slate due to the weather exposure.

How often do slate roofs need to be replaced

Naturally sourced slate roofing is built to last for a very long time. It can typically last for up to centuries. However, the roofs may need to be replaced if they are broken or if they are not correctly installed. You may also need to have the roof replaced if there is excessive flaking. If the roofs are installed well, you will not need to replace them for more than 80 years.
