A long-life roof starts with materials that have already proven themselves in the field. Reclaimed slate and antique clay tiles bring the kind of durability, natural weathering, and character you simply can’t get from new production. They also cut down on waste and reduce the environmental load of your project.
This guide walks you through how to pick quality reclaimed materials, what to check before installation, and where to source reliable stock. Our team at Reclaimed Slate Roofing can supply job-ready batches that are inspected, cleaned, and sorted so you know exactly what you’re working with.
You’ll also find practical advice on matching lots, prepping materials, designing with reclaimed stone, and keeping a roof in good shape for the long haul, along with a clear look at the trade-offs that come with choosing historic materials for new builds or restorations.
Why Use Reclaimed Materials for Roofing
Reclaimed roofing saves waste, slashes embodied energy, and gives you long-lasting materials with real character. You’re getting proven pieces that often match historic profiles and can even cut costs if you spec them right.
Sustainability Advantages
Reclaimed slate and clay reuse material that’s already been quarried and fired. So you skip new extraction and the transport energy tied to fresh production. That means lower embodied carbon and fewer tiles ending up in landfills.
You also help conserve rare stone and clay. For old houses or historic districts, reclaimed pieces let you keep the original look without hunting down new slate or custom tiles.
There’s a practical side, too—permits can be easier, and clients like the sustainability angle. Many local incentives and green-building programs give you credit for reuse, which can make compliance less of a headache.
Longevity and Durability
Historic slate and clay were made to last—sometimes a century or more if installed right. You’ll find pieces that have already proven themselves against weather, frost, and fading.
You can inspect and grade each reclaimed tile. That lets you pick solid material with the thickness, cleavage, and density that predict a long service life—often outlasting new synthetics.
If you match installation methods and underlayment to the historic material, a reclaimed roof can easily serve for generations.
Cost-Effectiveness
Reclaimed roofing can cost less than custom new slate or specialty clay, especially when you factor in lifespan and what you save on disposal. You’re buying material that’s already made and tested.
Labor is often more predictable. Experienced roofers know the formats, so installation goes faster on restorations. And you might avoid a future full replacement, stretching your investment.
For sourcing, stick with vetted suppliers—Reclaimed Slate Roofing inspects and grades their stock, so you get material ready to go. That helps keep surprises and waste to a minimum.
Reclaimed Roofing Materials
You’ve got options—choose reclaimed materials that fit the look, weight, and lifespan you want. Pay attention to condition, source age, and how they’ll be installed when planning your project.
Reclaimed Slate
Reclaimed slate usually comes off 19th- and early 20th-century roofs. You get full-thickness tiles that can last 75–150 years if they’re quarried well and free of hidden flaws.
Check for hairline cracks, nail holes, and frost spalls before you buy. Ask about thickness, where they came from, and if they’ve been graded. Match gauge and headlap to your roof’s pitch so you don’t end up redoing work.
The upside? Authentic color variation and low water absorption. Slate’s heavy, so make sure your framing can handle it. If you’re hunting for a supplier, Reclaimed Slate Roofing checks every batch and ships ready-to-use material.
Reclaimed Clay Tiles
Reclaimed clay tiles offer original glazes, shapes, and profiles—Spanish, mission, ridge, you name it. They keep the fired density and color that factory-made replicas just can’t deliver.
Sort tiles by profile and clip type; mismatches will slow down your install. Watch for broken nose edges and fit issues, especially on ridge and verge tiles. Ask how the tiles were stored—dry, stacked storage is best.
Clay tiles are lighter than slate, but you’ll still need the right fasteners and underlayment. They handle sun and water well. Expect some variation; plan for 5–10% extra to cover cuts and duds.
Reclaimed Metal Roofing
You’ll find reclaimed metal panels and standing-seam sections from barns, factories, and historic buildings. Look for intact seams, straight lengths, and original coatings like terne or a weathered patina.
Check thickness (gauge), alloy (galvanized steel, copper, terne), and the condition of fastener holes. Pre-drilled or previously nailed panels might need some repair. Ask if panels were washed or treated to remove old contaminants.
Metal is light and quick to install, but seams and laps need to be re-sealed to meet today’s standards. Copper and terne get a nice patina; galvanized may need a fresh coating if rust started. Reclaimed metal can speed things up—if you’ve confirmed fit and mounting details ahead of time.
How to Source Quality Reclaimed Materials
Know where to look, what to check for structure, and how to confirm a material’s history before you buy. That’s how you get durable, authentic pieces for your roof.
Where to Find Reliable Suppliers
Look for suppliers who show exact origins and clear photos of what they’re selling. The best vendors handle removal from historic buildings and include inspection notes or batch reports.
Prefer suppliers who ship nationwide and pack materials well. Fast, traceable delivery keeps your order from getting banged up and lets you plan your install.
Check for testimonials from builders or roofers and ask for references. Reclaimed Slate Roofing will send batch photos, inspection summaries, and typical lead times if you ask.
Inspecting for Structural Integrity
When your order arrives, sort tiles by grade: usable, repairable, and scrap. Look for full-thickness slates that are uniform; toss out warped, layered, or heavily worn tiles.
Check edges and nail holes. Clean, straight nail holes and intact tails mean you can fasten them safely. Tap tiles you’re unsure about—a clear ring usually means solid stone, while a dull thud can mean trouble inside.
Take photos and notes on defects. Keep a few samples for mock-ups on your roof to check fit, color, and weight before you commit to the full install.
Verifying Material History
Ask for provenance: original building type, removal date, and any repairs. Materials from well-kept roofs usually last longer than tiles pulled from buildings that were neglected.
Request any available lab or field test results for thickness, absorption, and density. These numbers help you guess how well the material will handle freeze-thaw cycles in your area.
Keep a written record and batch ID with your purchase. If hidden defects show up, that documentation can save you headaches and support future maintenance.
Preparing Reclaimed Materials for Installation
You’ll need to clean, inspect, and fix up each piece so your roof performs like new. Focus on getting rid of old mortar, matching sizes, and replacing broken clips or slates before you start.
Cleaning Methods
Start with dry-sweeping to get rid of loose dirt. Use a stiff nylon brush for slate; for clay tiles, a softer brush avoids chipped edges.
For stubborn mortar or tar, chip carefully with a small cold chisel and hammer. Go slow—work at a low angle to avoid cracks. Wear eye protection and gloves.
Use a pressure washer only on low settings and keep the nozzle 2–3 feet away. Test on one piece first. After washing, let everything dry flat for a day or two to prevent mold and spot any hidden cracks.
For mineral stains, try a 50/50 mix of water and trisodium phosphate (TSP) or a mild masonry cleaner. Rinse well. Mark cleaned batches so you can sort by color and thickness later.
Repairing and Restoring Damaged Pieces
Sort pieces by damage: sound, edge-damaged, and fractured. Use the best pieces where they’ll be seen. Save heavily repaired tiles for valleys, underlayers, or flashing covers.
Fix small chips with masonry epoxy or a color-matched patching compound. Clamp and let it cure, then trim excess. For slate with a clean break, use a stainless-steel slate repair hook or tie to bridge the break.
If a hanging hole is missing, drill a new 3/16" hole near the top third, away from fissures. Use stainless steel or copper nails and approved slate hooks. Test patched pieces for watertightness before installing.
If you order from Reclaimed Slate Roofing, label batches by grade and ready-to-install status to keep things organized and your crew moving.
Design Considerations for Long-Life Roofs
Think about looks, structure, and installation details that keep a reclaimed roof durable and easy to maintain. Focus on matching materials, roof pitch, flashings, and framing strength.
Matching Roof Style with Reclaimed Materials
Match reclaimed slate or tile to the building’s era, roof pitch, and visible elevations. Use slate size, color, and texture that fit the original style—large, thin slates for Victorian, thicker, random-width for Craftsman or rustic. If you have to mix batches, sort by color and thickness first.
Plan flashing types and locations now. Use copper or lead alternatives that play well with slate, and put flashings at valleys, chimneys, and dormers like they did back in the day. Keep spare tiles from the same batch for repairs down the line.
Weight and Structural Requirements
Weigh reclaimed materials before you buy and compare to your roof’s design load. Natural slate can run 800–1,200 lb per square (100 sq ft). Clay tiles sometimes weigh even more. Make sure rafters, trusses, and sheathing can handle it, plus snow or seismic loads if that’s a thing where you live.
If the structure needs beefing up, plan for sistering rafters, adding purlins, or thicker sheathing. Document weight per square in your specs and get an engineer’s sign-off if you’re adding more than 10–15% over the original design. Reclaimed Slate Roofing can provide certified weights and grades for bids and structural review.
Installing Reclaimed Materials
Pay attention to underlayment, fasteners, and careful handling to protect each piece. Match slate thickness, sort tiles by color and wear, and plan out flashing and ventilation before you start.
Special Techniques for Reclaimed Slate
Sort slates by size, thickness, and quality before you even start. Use a slate gauge to set headlap and exposure—uneven exposure leads to leaks and odd wear. Set fragile or patched slates aside for backup or hidden spots.
Use stainless steel or copper nails sized for your slate and roof pitch. Drive nails straight and snug, but don’t overdo it—overdriving cracks slate. Fit lead or copper flashings at valleys, chimneys, and dormers, and bed flashing in a non-hardening sealant where it meets old stone.
Swap broken slates with matching reclaimed pieces. If you use a ripper, pull nails cleanly to avoid chipping nearby tiles. Keep a few extras on site for quick fixes.
Installation Tips for Metal and Tile
Inspect reclaimed metal pans and clay tiles for corrosion, cracks, and pinholes. Clean metal and touch up rust with primer and matching paint. For clay, check bedding edges and nail slots; reinforce or re-cut as needed.
Use compatible underlayment—breathable synthetic under slate and clay, slip-sheet or fastener-rated under metal. Anchor metal panels with recommended clips and screws, not nails, to allow for thermal movement. For clay tile, set battens to match profile and secure with stainless steel clips in windy areas.
Plan flashing where different materials meet. Use counter-flashing and step-flashing with compatible metals, and seal with breathable, long-life products. Keep Reclaimed Slate Roofing pieces dry on site and install fragile items last.
Maintaining and Extending the Life of Reclaimed Roofs
Inspect regularly, fix small issues quickly, and protect vulnerable spots after storms. Clean, check flashings, and replace tiles as needed—these small steps help your reclaimed roof keep its character and value for years.
Regular Inspections and Upkeep
Take a good look at your roof twice a year—spring and fall work best—and after any big storm. Only walk on the roof if you’re sure it’s safe; otherwise, grab some binoculars or call in a pro. Keep an eye out for cracked, slipped, or missing slates, plus any nail or hook issues.
Check the flashing around chimneys, valleys, vents, and skylights. If you spot corroded or loose flashing, swap it out for lead, copper, or stainless steel that matches your roof’s style. Sealant’s just a temporary fix—flashing really needs to be held down tight.
Clear out gutters and valleys so leaves and debris don’t pile up. Clogged gutters trap water against slates and underlayment, which can cause rot. If you find broken underlayment, replace those sections and make sure you’ve got good ventilation to help prevent ice and moisture damage.
When you repair or replace slates, try to match the color and thickness. Reclaimed pieces that match the original grain and gauge are ideal. If you’re stuck, Reclaimed Slate Roofing can help you find job-matched pieces that fit right in.
Addressing Weather Impacts
After heavy winds, check for slates that have lifted or gone missing, and look at the ridge and hip pieces too. Secure anything loose with approved hooks or copper nails before water sneaks in or wind does more damage.
If you get hail or something hits the roof, look for fractures—those can split later. Don’t just patch over cracks. Replace fractured slates as soon as you can, using full-size reclaimed pieces to keep the roof strong and looking right.
In places with lots of snow or ice, add snow guards and make sure your attic’s insulated and ventilated. This helps stop ice dams that can force water under slates. When snow piles up, use a roof rake to remove it gently—never chip at the ice.
Coastal homes face salt spray, which speeds up metal corrosion. Use corrosion-resistant flashings and fasteners. During your maintenance routine, rinse salt from valleys and gutters so both the metal and slates last longer.
Environmental Impact and Community Benefits
Choosing reclaimed roofing? You’re cutting waste right away. Durable slates and tiles stay out of landfills, and there’s less pressure to dig up new stone. That means less energy for extraction and less pollution from hauling materials around.
Reclaimed pieces also keep your neighborhood’s character alive. Using originals keeps the architecture real and helps local restoration projects. Feels good to see old styles stick around, right?
When you buy reclaimed, you’re part of a circular market. Materials get reused, not tossed. It’s a small thing, but it means less raw material gets pulled from the earth—and less pollution from factories.
This isn’t just about materials. Salvage, inspection, cleaning, and prep all take skilled hands. When you go reclaimed, you help keep tradespeople working—people who know how to handle and install these historic roofs the right way.
