Types of Slate Roofing Material
There are three main categories of slate roofing products available:
Natural Slate
- Characteristics: Quarried slate stone that is hand-split or machine cut into shingles/tiles. Considered the highest quality and most expensive option.
- Pros and Cons: Offers unmatched beauty and durability but also heavier and more fragile than synthetic alternatives. Needs experienced installers.
Synthetic Slate
- Characteristics: Roofing made to mimic natural slate but composed of recycled plastic and rubber polymers. More lightweight.
- Pros and Cons: Cheaper and easier to install than natural stone but may fade faster and have a less natural look over time.
Composite Slate
- Characteristics: Roofing material made by embedding colouring and strengthening agents within concrete or fiber cement.
- Pros and Cons: Durable, fire/impact resistant, and requires little maintenance. Won’t fade but may seem less authentic than natural or synthetic slates.
