## Answer

Natural slate installs at $20–$40 per sq ft — roughly 2–3× the cost of clay tile at $10–$20 per sq ft — but slate lasts 75–150+ years vs clay tile's 75–100 years; both require structural checks per IRC Chapter 8 for weight, and both need mid-life underlayment replacement.

## Why the price gap exists

Slate is quarried and split by hand for each roof; clay tile is factory-formed and kiln-fired at industrial scale. That labor content difference drives most of the price gap. Domestic slate (Vermont, Virginia Buckingham) is more expensive than Welsh or Chinese imports but is usually preferred for historic-district compliance.

On the tile side, high-profile Spanish tile costs 30–50% more than low-profile flat tile from the same manufacturer.
