Tarco Specialty Products, Inc.

Tarco Specialty Products, Inc. ("Tarco") is a privately held U.S. roofing-materials manufacturer headquartered at One Information Way, Suite 225, Little Rock, Arkansas. It is not publicly traded and no parent company is disclosed in the sources reviewed. The company traces its underlayment production to 1978, and third-party data provider Crustdata lists roughly 42 employees, which is consistent with a mid-sized, privately owned manufacturer; no revenue figure is publicly verified. It also operates under the Tarco Roofing brand (tarcoroofing.com).

Operations. Tarco describes itself as one of the largest independently owned manufacturers of residential and commercial roofing and building-envelope products in North America. Its product lines include asphalt-saturated organic felts and fiberglass felts, organic base sheets, mineral-surfaced roll roofing, and the LeakBarrier-branded family of premium underlayments — EasyLay synthetic underlayments, EasyBase and EasyStick Plus self-adhering SBS base/cap membranes, Ice & Water Armor, EasyTorch APP torch-applied membranes, EasyNailBase, and ValleyFlash, along with asphalt and butyl tapes and door-and-window tape. It holds Miami-Dade, Florida Building Code, ICC, TDI and UL approvals for many of these products. Manufacturing is located in North Little Rock, Arkansas; Greencastle, Pennsylvania; and Belton, Texas.

Litigation posture. Tarco is an operating company, not an assertion entity. In the tracked data it appears once, solely as a defendant (0 plaintiff cases, 1 defendant case), the classic profile of a manufacturer targeted by a non-practicing licensor.

Notable case. Kirsch Research & Development, LLC v. Tarco Specialty Products, Inc., No. 6:20-cv-00318-ADA (W.D. Tex., Waco Division), filed April 24, 2020. Plaintiff Kirsch asserted roofing-underlayment patents (U.S. 6,308,482 and 8,765,251) in a coordinated campaign against multiple building-products companies, including GAF, Owens Corning, IKO, Atlas Roofing, CertainTeed and BlueLinx. Kirsch's U.S. 6,308,482 was invalidated by the PTAB in IPR2021-00192 at GAF's request, a decision the Federal Circuit affirmed in May 2024. The ultimate disposition of the Tarco action is not reflected in the tracked case data.
