What a Westlake Royal Saxony 900 Slate roof costs
Our quote engine's price for a roof of clay and concrete roof tile at a 6/12 pitch, old layer torn off, at US-average roofer wages. The roof is bigger than the house: the pitch adds about 12% to the footprint.
| House footprint | Roof | Installed |
|---|---|---|
| 1,500 sq ft | 16.8 squares | $26,700–$30,700 |
| 2,000 sq ft | 22.4 squares | $35,400–$40,700 |
| 2,500 sq ft | 28.0 squares | $44,100–$50,800 |
The engine prices clay and concrete roof tile as one class, not by brand, so these figures are the same on every line of that class we cover. Within the class, roof size, pitch, tear-off and local labour move a price far more than the label on the bundle; what Saxony 900 Slate costs your roofer depends on their supplier, so ask for it by name. Prices in your state: roof replacement cost by state.
