What is Slate Roofing?
Slate roofing is a premium, natural stone material used for roofing. It is highly durable, fire-resistant, and aesthetically appealing, often found on high-end or historic homes. Slate tiles are cut from slabs of stone, creating flat, rectangular tiles that interlock to form a waterproof barrier. Known for its long lifespan (100+ years), slate is also resistant to severe weather conditions like high winds and heavy rain. However, it is expensive and requires skilled installation due to its weight and fragility.
Types of Slate Roofing
Natural Slate
Natural slate roofs are made from quarried stone. This type of slate is the most traditional and durable option.
However, because of the weight of natural slate, you may need to add structural support, which could cost an additional $2,000 to $5,000.
Synthetic Slate
Synthetic – or composite – slate is made from polymer-based materials or recycled rubber, mimicking the look of natural slate.
Synthetic slate is less expensive than natural slate. It is also lighter than natural slate meaning it is unlikely to require additional structural support.
