The Durable Slate Company

What The Durable Slate Company does

The Durable Slate Company, founded in 1986 in Columbus, Ohio, is a privately held specialty roofing contractor focused on the installation, repair, restoration, and maintenance of historic roofs using natural materials — slate, clay tile, and copper. The company serves a diversified client base including individual property owners, churches and religious institutions, government buildings (e.g., Maryland State House, Baltimore City Hall, Norwegian Embassy), educational institutions (Carroll College, St. John's College, Peabody Institute), healthcare facilities (Walter Reed), museums (Walters Art Museum), and commercial customers such as Ivy Hotel. Its service portfolio spans slate roofing, tile roofing, copper roofing, copper gutters, ornamental metal fabrication, reclaimed slate sourcing, maintenance/repair, and expert consulting, supported by a paid apprenticeship program and one of the largest reclaimed slate inventories in the United States.

Operationally, the company runs from multiple U.S. branch offices — Columbus, Cleveland, and Cincinnati in Ohio, plus a Mid-Atlantic regional branch in Savage, Maryland (with extended coverage across the Baltimore–Washington corridor and adjacent states) — and claims availability for international projects. Its core technology is traditional craft executed through skilled tradespeople, augmented by an inventory of reclaimed slate sourced from Vermont Slate Valley, Virginia Buckingham, Southeastern Canada, Wales, and select European quarries that enables matching of original materials on historic structures. The company operates a sister entity, Durable Restoration Company, which handles complementary restoration services such as window repair and water intrusion mitigation.

The revenue model is project-based professional services: customers request estimates through a toll-free number or website, receive free on-site estimates within a defined coverage area (Ohio, Indiana, Michigan, Pennsylvania, Kentucky, West Virginia, Virginia, Washington D.C., Maryland), and pay via quote-based pricing with logistics fees applied for work outside the core service territory. The go-to-market motion is enterprise field sales supported by phone outreach, a website with multiple calls-to-action, and profiles on Google, Yelp, and Facebook. Notable awards include the NRCA Gold Circle Award and an IFD Award, and the company holds an A+ Better Business Bureau rating.

Broad incumbents

• Greenwood Industries: Sheet metal and roofing contractor with a long history in architectural metal and standing-seam roofing; closely comparable to The Durable Slate Company's copper roofing and ornamental metal capabilities, though broader in scope and not historic-specialty focused.
• CentiMark Corporation: National commercial roofing services company offering roof replacement, repair, and maintenance; comparable in service mix and customer base but at substantially larger scale and without the historic-slate specialization.
• Flynn Group: North American roofing and insulation contractor serving commercial customers across Canada and the U.S.; comparable as a roofing services incumbent with similar install/repair/maintenance revenue streams, though oriented to modern systems rather than historic materials.
• Tecta America: National commercial roofing company serving commercial and industrial facilities with installation, repair, and maintenance; comparable in service mix and enterprise customer base but lacks Durable's specialty slate/copper/tile focus.
• Bone Dry Roofing: Midwest-focused residential and commercial roofing chain with regional branches; comparable as a multi-branch regional roofing contractor but concentrated on mainstream residential materials rather than historic specialty roofing.
• Baker Roofing Company: Southeast U.S. residential and commercial roofing contractor of comparable size and tenure; shares the multi-branch regional service model and full-service install/repair/restoration offering, though not focused on historic materials.

Others

• Wiss, Janney, Elstner Associates (WJE): Architectural and engineering consultancy specializing in building preservation and restoration; adjacent to Durable's historic roofing work through shared clients in heritage preservation, although WJE delivers engineering/consulting services rather than installation.

• North Country Slate: U.S. distributor of natural slate roofing products; an upstream supplier and product peer relevant to Durable's slate roofing supply chain, for both new installation and reclaimed slate sourcing.
• Revere Copper Products: Manufacturer of copper sheet, plate, and architectural copper products for roofing and gutter applications; upstream material supplier to Durable's copper roofing services and a key node in the same specialty materials ecosystem.
