What Is Slate?
Slate is a versatile building material fashioned into thin sheets, primarily used for roofing and exterior walls. The material’s longevity varies based on the housing environment, generally necessitating re-painting approximately every 10 years, with the potential need for partial repairs in case of cracks. It comes in various forms: natural slate from slate rock, decorative slate from cement mixed with fibers, and laminated slate offering a broad color palette to complement exterior wall paints. Installation involves placing a waterproof sheet over the base plate and securing the slate with nails.
Uses of Slate
Slate’s applications extend to both roofing and exterior wall finishes. Decorative slate, in particular, offers several benefits:
- High earthquake resistance due to its lightweight nature.
- Cost-effectiveness.
- Widespread contractor availability for installation.
Its lightweight and ease of installation make it suitable for complex roof designs. However, decorative slate has its drawbacks, including susceptibility to cracking, moss, and mold, and lower durability and water resistance. It also requires regular painting maintenance.
