Old slate roofing is commonly purchased by architectural salvage companies, reclaimed building material dealers, historic restoration contractors, landscapers, and homeowners repairing slate roofs. Because slate tiles can last more than a century, many removed tiles remain valuable and reusable.
When a slate roof is replaced or a historic building undergoes renovation, the tiles are often salvaged rather than discarded. Reclaimed slate is used for roof repairs, restoration projects, landscaping, flooring, and decorative stonework.
Understanding who buys old slate roofing and how the market works can help homeowners, contractors, and demolition companies turn removed roofing materials into a profitable asset instead of construction waste.
Why Old Slate Roofing Still Has Value
Slate roofing is made from natural metamorphic stone that forms under high pressure in the earth. Unlike asphalt shingles, slate tiles are extremely durable and resistant to weather, fire, and rot.
Many slate roofs installed in the United States during the late 1800s and early 1900s are still functioning today.
Typical lifespan of slate roofing:
- Soft slate: 75–125 years
- Hard slate: 150–200+ years
Because of this longevity, even tiles removed during roof replacement often remain usable.
New slate roofing is expensive, which creates strong demand for reclaimed materials.
Typical Market Prices in the United States
| Material | Typical Price |
|---|---|
| Reclaimed slate tile | $5–$15 per tile |
| Reclaimed slate roofing square | $200–$600 |
| Broken slate for landscaping | $50–$200 per pallet |
Prices depend on condition, thickness, tile size, color, and quarry origin.
Common Buyers of Reclaimed Slate Roofing

1. Architectural Salvage Companies

These companies clean, sort, and resell slate tiles to restoration contractors or homeowners who need matching replacement pieces.

How to Sell Slate Roof Tiles Successfully
Selling reclaimed slate roofing is easier if the tiles are properly removed and prepared.
Step 1: Inspect Tile Condition
Examine tiles for:
- cracks

- excessive wear
Tiles in good condition command higher prices.
Step 2: Remove Tiles Carefully

- thickness
- color
Stacking similar tiles together makes resale easier.

Slate should be stored vertically or stacked carefully on pallets.
Using pallet storage prevents tiles from cracking during transport.

Reach out to:
- architectural salvage companies
- roofing contractors
- reclaimed building material dealers

Providing clear information helps attract serious buyers.
Include details such as:
- number of tiles available
