Slate roofing maintenance does not incur high costs because, in relation to its long lifespan, the operation required for maintenance are minimal. ON the other hand, replacing damaged slates is very simple, as it only requires replacing the affected pieces. It simply involves removing the corresponding nail or hook and replacing the piece with a new one in good condition. Additionally, it is considered that slates have a self- cleaning surface, meaning that dirt accumulation is minimal.

Galician slate undergoes rigorous quality controls that certify it as an optimal product for such use. The mandatory UNE standards and the test carried out at the Slate Technology Center Laboratory certify the quality of the product. Additionally, the CE marking distinguished the quality of Galician slate from countries like China or Brazil, which lack any marking.

Without a doubt, slate has properties that are difficult to match by other materials like ceramic tiles, copper, zinc, or others. These include its excellent quality/price ratio; it is great durability, which allows it to remain unchanged against humidity, dust, salt, cold, heat, snow, or wind; it is high impermeability and low water absorption ( slate has an absorption rate of 0,40%, while ceramic tiles can reach up to 12%, according to data provided by LOMCO); its thermal and acoustic properties; its low maintenance and minimal dirt accumulation ; and its contribution to the environment, as it is a product with a very low carbon footprint.

It is said that slate offers a good quality/price ratio because, being a material with great durability and low maintenance, the cost related to both the materials, its installation, and maintenance throughout its lifespan are very competitive compared to other materials.
