Structural Weight

Natural slate is heavy. The roof structure may need evaluation before installation.

Specialized Labor

Slate roofing requires experienced installers, proper flashing, and careful handling to prevent breakage.

Long-Term Investment

Slate can be expensive upfront but may provide long service life when installed and maintained correctly.
