Slate Scalloped Stone Roof

Slate is hard-wearing and durable but it can easily crack under pressure. That's why professionals use hook ladders, jacks and planks on slate roofing. This allows them to walk on the roof without putting any weight on it.

Slate forms naturally when layers of rock are exposed to extreme pressure and heat, so it's no surprise that it's so resistant to fire. This natural property makes slate a great choice for roofing material as it reduces the chances of a building's roof catching alight in the event of a fire.

As slate is a type of metamorphic rock, it creates a fireproof and waterproof roof. Because they last so long and produce very little waste, slate roof tiles are also a sustainable roofing option.

Slate tends to be more expensive than tiles. It is also double lapped to perform a watertight layer, which adds to the cost of installation. However, it's long-lasting properties usually mean that after the initial cost, you will have very few expenses on your roof for many years to come.

Regular maintenance should include cleaning gutters at least twice during the fall and once in early spring, and replacing damaged slates promptly. Every five to seven years inspections should be conducted by professionals experienced in working with slate and steep slopes.
