Despite all of its advantages, there are also some potential disadvantages to using slate roof tiles. One of the main disadvantages is that it is a dense and heavy material, which means that it requires a strong and sturdy roof structure to support the extra weight. This can make installation more challenging and may require additional reinforcement and retrofitting to make it suitable for existing roof structures.
Additionally, these tiles are typically more expensive than other roofing options, such as asphalt shingles. However, the cost of slate tiles is often justified by their long lifespan and minimal maintenance requirements. Additionally, their cost can vary depending on the quality of the tiles and the location of the installation.
Another disadvantage of slate roof tiles is that since it is a fine-grained sedimentary rock, some pieces are prone to cracking or splitting off into thin slices if they are not handled properly. Additionally, once one of these tiles gets damaged, they can be difficult and costly to repair or replace. This can be a major concern for homeowners who live in areas prone to severe weather.
