How much can I sell slate for? Short answer: usually anywhere from $20 to $120 per square metre, depending on quality and demand. And yes—slate from old roofs can be worth more than slate from old pool tables. Want the best price (and fewer surprises)? Keep reading.

Selling slate can feel confusing at first. Prices shift depending on quality, origin, and what buyers need at the moment.
Once you understand how slate is graded and valued, it becomes much easier to decide whether yours is worth a quick sale or deserves a premium price.
The sections below will help you judge exactly where your slate sits in the current market.

Understanding the Market Value of Salvaged Slate Materials (1 of 2)

Slate value depends on more than age or appearance.
Buyers look closely at type, condition, and whether the pieces are suitable for roofing or just for craft projects.
This section breaks down the essentials so you can identify which category your slate belongs to.

Determining the Value of Reclaimed Roofing Slate (1 of 5)

Current Price Ranges Per Piece and Per Square Foot

Reclaimed slate often sells for around $1–$5 per piece, depending on condition and type.
When priced by the square metre, typical ranges fall between $30 and $120, with premium reclaimed lots sitting at the upper end.
These prices can rise further when the slate is uniform, pre-sorted, and free from damage.

How Slate Origin (Welsh, Spanish, etc.) Impacts Price

Slate from Wales tends to command the highest price because of its durability and long life.
Cumbrian slate also performs well, though availability varies.
Imported slate is usually cheaper, partly because it lacks the historical reputation and aesthetic consistency that many UK buyers prefer.

The Distinction Between New and Reclaimed Slate Prices

New slate can be cheaper than reclaimed when it comes from budget sources.
Reclaimed slate, however, is often more valuable due to its patina and suitability for restoration projects.
Premium reclaimed stock is harder to find, which naturally pushes the price upward.

Key Factors That Skyrocket or Decimate Your Slate’s Price (2 of 5)

Condition, Quality, and Grade (The “Knuckle Test”)

Condition makes the biggest difference in value.
A clean, solid slate should give a clear ring when tapped—this is a simple way to check internal strength.
Pieces with cracks, chips, or rust staining drop sharply in price, and some may be unsellable for roofing use.

Rarity, Colour, and Historical Significance

Less common shades such as purple or sea-green often attract higher prices.
Slate from historically important buildings or closed quarries can also be more valuable.
Buyers in the restoration sector often pay extra for materials that match heritage requirements.

Required Quantity and Lot Size for Commercial Buyers

Contractors and roofers prefer larger batches.
Lots under 300–500 pieces usually sell more slowly and for less.
Uniform size and thickness also help achieve a better price, as mixed batches take more work to sort.

The Secondary Market: Selling Pool Table and Craft Slate (3 of 5)

Valuation of Used Pool Table Slate

Pool table slate holds value when it’s in one piece or a clean three-piece set without cracks.
Because it’s thick and precisely machined, many buyers repurpose it for workshops or craft projects.
Damaged slate may still sell, though typically at a reduced price.

Alternative Uses for Low-Grade or Damaged Pieces

Even broken or irregular pieces can be reused.
Garden paths, outdoor signs, craft boards, and decorative projects all make use of lower-grade slate.
Selling slate for repurposing also helps avoid disposal costs.

Practical Guide: How and Where to Sell Your Slate for Maximum Return (2 of 2)

To get the best price, it helps to prepare your slate properly and choose the right selling route.

The next steps focus on the parts of the sale you can control.

The Importance of Cleaning, Sorting, and Palletising

Clean slate sells faster and commands better prices.
Removing mud, moss, and debris helps buyers assess the condition without guessing.
Sorting by size and stacking neatly on pallets signals professionalism and makes the lot more attractive.

Selling “As Is” vs Offering Removal Services

Offering delivery or having the slate palletised saves buyers time and labour.
Because of this, sellers who provide those services often achieve higher prices.
“As is” sales still work but usually appeal more to hobbyists than contractors.

Choosing the Best Selling Channels to Find Buyers (5 of 5)

Reaching Out to Architectural Salvage Yards and Speciality Distributors

Architectural salvage yards are strong buyers of reclaimed slate, especially older or historically significant stock.
They understand grading and may buy in bulk, which simplifies the process for you.
This option can save time if you have a large quantity to sell.

Listing on Online Marketplaces (eBay, Craigslist, Specialty Forums)

Online platforms work well for both commercial and craft buyers.
Clear photos and detailed descriptions help your listing stand out.
Including size, thickness, quantity, and condition reduces back-and-forth messages and leads to faster sales.

Contacting Local Historic Restoration Contractors

Restoration specialists often need reclaimed slate urgently for heritage work.
Local builders and roofers may also be interested if your slate matches what they use regularly.
Building relationships with tradespeople can lead to future sales or bulk orders.
