Flintkote Roofing Shingles

Product Description

Flintkote Company was one of the most prominent building materials manufacturers in the United States throughout much of the twentieth century, producing a wide range of construction products that were distributed nationally across residential, commercial, and industrial markets. Among its extensive product line, Flintkote manufactured roofing shingles that were widely used on homes, commercial buildings, and industrial facilities throughout the country.

Flintkote’s roofing shingles were considered a standard-grade product during the decades when asbestos was a commonly accepted additive in roofing materials. The company marketed these shingles as durable, fire-resistant, and weather-proof — properties that were largely attributed to the incorporation of asbestos fibers into the shingle matrix. Flintkote distributed its roofing products through building supply chains, roofing contractors, and wholesale distributors, meaning the shingles reached an enormous geographic footprint over the years they were produced.

The company’s broader product portfolio also included ceiling tiles, cement pipe, floor tiles, joint compound, pipe insulation, and other roofing products — all categories in which asbestos was a common raw material during the mid-twentieth century. This wide-ranging use of asbestos across Flintkote’s product lines became a central issue in subsequent litigation as the health consequences of asbestos exposure became scientifically and legally established.

Flintkote eventually faced significant financial pressure from mounting asbestos liability claims and entered bankruptcy proceedings. The company’s asbestos-related legal history has been extensively documented in civil litigation across multiple jurisdictions in the United States.

Asbestos Content

Roofing shingles manufactured during the period when asbestos was an industry-standard additive commonly incorporated chrysotile asbestos, and in some product lines, amphibole asbestos types such as amosite or tremolite. Asbestos fibers were blended into the base mat or felt underlayer of the shingles and were also mixed into the asphalt or binding compounds used in the manufacturing process. The fibers served a structural function, reinforcing the shingle against cracking, improving fire resistance, and extending weathering performance — characteristics that made asbestos highly valued by manufacturers during this era.

Plaintiffs in litigation involving Flintkote alleged that the company’s roofing shingles contained asbestos as a deliberate material component and that this asbestos content posed a significant health hazard to workers who handled, cut, installed, or removed these products. Litigation records document claims that Flintkote was aware of the hazardous nature of asbestos fibers over a period of years yet continued to manufacture and distribute products containing asbestos without providing adequate warnings to workers or end users.

The presence of asbestos in roofing shingles is regulated under current federal law. The U.S. Environmental Protection Agency’s Asbestos Hazard Emergency Response Act (AHERA) and related regulations establish standards for identifying, managing, and abating asbestos-containing building materials, including roofing products. OSHA’s asbestos standards for construction work (29 CFR 1926.1101) specifically address roofing materials as a category of asbestos-containing material (ACM) that requires protective measures during handling and removal.

How Workers Were Exposed

Industrial workers and tradespeople encountered Flintkote roofing shingles at multiple stages of the product’s lifecycle, from manufacturing through installation and eventual removal or demolition.

Manufacturing Workers employed at Flintkote facilities where roofing shingles were produced were exposed to raw asbestos fiber during mixing, pressing, and finishing operations. These workers often labored in environments where airborne asbestos dust was generated in quantity, and litigation records document allegations that adequate respiratory protection and engineering controls were not consistently provided.

Roofing Contractors and Installers handled shingles directly during installation on new construction projects. Cutting shingles to fit roof dimensions — using saws, snips, or scoring tools — generated asbestos dust that became airborne in the immediate work area. Workers performing this type of work on a repeated, daily basis over the course of a career would have accumulated significant cumulative exposure.

Demolition and Removal Workers faced potentially higher exposure risks when removing old roofing shingles from structures undergoing renovation or demolition. Aged and weathered asbestos-containing shingles can become friable — meaning they crumble easily — releasing asbestos fibers into the air more readily than intact shingles. Plaintiffs alleged that workers engaged in teardown and re-roofing work on structures covered with Flintkote shingles were exposed to harmful concentrations of airborne asbestos fibers without adequate warnings or protective equipment.

General Industrial Workers who worked in or around facilities where Flintkote shingles were stored, transported, or used in construction may also have experienced secondary or bystander exposure. Litigation records document claims from workers in a variety of industrial settings where roofing work was performed as part of larger construction or maintenance projects.

The diseases associated with occupational asbestos exposure include mesothelioma, lung cancer, asbestosis, and other asbestos-related conditions. These diseases typically have a long latency period — often twenty to fifty years between initial exposure and diagnosis — meaning that workers exposed to Flintkote roofing shingles decades ago may only now be receiving diagnoses.

Documented Trust Fund / Legal Options

Flintkote’s asbestos liability history is classified under Tier 2 — Litigated, meaning that claims against the company are pursued through the civil court system rather than through a pre-established asbestos bankruptcy trust fund that is currently accepting claims. Litigation records document extensive civil litigation against Flintkote across multiple state and federal jurisdictions, with plaintiffs alleging that the company’s asbestos-containing products, including roofing shingles, caused serious and fatal diseases.

Individuals diagnosed with mesothelioma, lung cancer, asbestosis, or other asbestos-related diseases who have a documented history of exposure to Flintkote roofing shingles may have legal standing to pursue claims. Litigation records document that plaintiffs have alleged product liability, failure to warn, and negligence as grounds for recovery against Flintkote and related corporate entities.

Steps for Affected Workers and Families:

• Document exposure history — Employment records, union records, co-worker affidavits, and contractor records that establish contact with Flintkote roofing shingles are essential to supporting a claim.
• Obtain medical records — A confirmed diagnosis from a qualified physician, including pathology reports and imaging studies, is a foundational requirement for any asbestos claim.
• Consult an asbestos attorney — Given the complexity of Flintkote’s corporate and litigation history, an attorney with specific experience in asbestos product liability can evaluate the appropriate legal avenue, jurisdiction, and strategy for each individual claim.
• Investigate related product exposure — Because Flintkote manufactured a broad range of asbestos-containing products across multiple categories, exposed workers may have claims related to other Flintkote products in addition to roofing shingles.

Statutes of limitations govern the time period within which asbestos claims must be filed, and these deadlines vary by state and by date of diagnosis. Affected individuals and their families are encouraged to seek legal consultation promptly following a diagnosis to preserve all available legal options.
