Roofing Products Asbestos Exposure

Roofing Products and Historical Asbestos Use

Historical asbestos-containing roofing materials were used on commercial, industrial, military and residential buildings. Asbestos could be incorporated into products intended to resist weather, heat, flame and physical wear.

Potential asbestos content varied widely by manufacturer and product type. Some materials contained asbestos fibers throughout the product, while others used asbestos in backing, reinforcement, coatings or mastics.

Roof repairs can also create a layered exposure history because new products may be installed over older materials instead of replacing the entire system.

Types of Asbestos-Containing Roofing Products

Depending on product and year, historical asbestos-containing roofing materials may have included:

• roofing felt and saturated felt products;
• asbestos-cement roofing sheets or panels;
• asbestos-containing shingles;
• roofing mastics and adhesives;
• roof coatings and sealants;
• flashing compounds and patching materials;
• built-up roofing components;
• roof underlayment or backing materials;
• corrugated asbestos-cement roof panels; and
• specialty heat- or fire-resistant roof products.

Historical roofing felt should be distinguished from other felt products because formulation and use differed by product line. Likewise, roofing mastics should be identified separately from flooring adhesives even when the products look similar.

How Asbestos Exposure Could Occur

A potential exposure pathway requires asbestos-containing roofing material and work that disturbs it. Intact, non-friable products may release fewer fibers than materials that are cut, drilled, ground, broken, torn or heavily weathered.

Potential disturbance could occur during tasks such as:

• cutting asbestos-cement roofing sheets;
• drilling holes for fasteners or roof equipment;
• breaking or removing old shingles;
• tearing off roofing felt;
• scraping hardened roofing mastic or coatings;
• grinding or sanding roof surfaces;
• removing flashing or patching compounds;
• demolishing roof decks or roof assemblies;
• handling broken roofing debris; and
• dry sweeping or blowing dust from roof surfaces.

Actual exposure depends on asbestos content, product condition, friability, weathering, work method, frequency, duration, proximity, ventilation and controls.

Workers and Job Sites That May Have Encountered Asbestos Roofing

Workers who manufactured, installed, repaired, removed or worked near historical asbestos-containing roofing materials may have encountered airborne fibers. A job title alone does not establish exposure; the exact product and task matter.

Potentially relevant occupations may include roofers, construction laborers, carpenters, sheet-metal workers, maintenance workers, demolition crews, building engineers, industrial workers and military construction personnel.

Possible settings include factories, warehouses, power plants, schools, hospitals, offices, military facilities, apartment buildings, houses and other structures with older roof systems.

Nearby workers may also be relevant when roof cutting, tear-off, repair or demolition generated dust in shared work areas or on lower levels where debris was handled.

Repair, Removal and Demolition Risks

Roof tear-off

Tearing off old roofing can disturb multiple layers at once. Felt, mastics, shingles, coatings and underlayment may all require separate identification.

Cutting and drilling

Asbestos-cement sheets or panels may release fibers when sawed, drilled or broken. Fastener removal and installation of vents, flashing or rooftop equipment can also disturb older materials.

Mastic and coating removal

Roofing mastics and coatings can remain bonded to flashing, decking or other surfaces. Scraping, grinding or mechanical removal may disturb asbestos-containing residue if present.

Weathered roofing

Heat, sunlight, water intrusion and age can degrade roofing materials. Damaged surfaces may break more easily during repair or removal.

Demolition and debris handling

Roof demolition can produce broken panels, shingles, felt and adhesive debris. Dropping, crushing, loading or sweeping this material can create additional disturbance.

Evidence That May Identify Historical Roofing Products

Exposure reconstruction is strongest when evidence identifies the exact roofing product, manufacturer, building, installation or removal period and work performed.

Useful evidence may include:

• manufacturer names, brand names and product numbers;
• roofing bundles, cartons, rolls, buckets or labels;
• historic roofing catalogs and technical literature;
• architectural specifications and roof schedules;
• purchase orders, invoices and supplier records;
• roofing contractor and repair records;
• maintenance and reroofing documentation;
• demolition and abatement records;
• historic photographs showing roofing products in place;
• asbestos surveys and bulk-sample laboratory reports;
• employer, union or military records documenting assignments;
• coworker or supervisor statements identifying products and tasks; and
• qualified laboratory analysis of surviving roofing material when appropriate.

Testing should distinguish felt, shingles, cement panels, mastic, coatings and other roof layers whenever those components can be separately identified.

Medical and pathology records may document an asbestos-related diagnosis but do not establish which historical roofing product was an exposure source.

Secondhand Exposure and Health Risks

If work with asbestos-containing roofing materials generated fibers that accumulated on clothing, shoes, tools or belongings, asbestos could potentially have been carried away from the job site. This is a possible secondhand exposure pathway, but family relationship alone does not establish exposure.

Asbestos exposure is associated with mesothelioma, asbestos-related lung cancer, asbestosis and other asbestos-related disease. Working around older roofing products does not diagnose disease and does not establish individual medical causation.

Anyone concerned about historical occupational asbestos exposure should discuss their work history and health with a qualified healthcare professional.

Legal and Compensation Considerations

Depending on the evidence and circumstances, legal options may be available to a person diagnosed with an asbestos-related disease after documented exposure to a specific asbestos-containing roofing product.

A legal review may consider the manufacturer, product line, building or job site, installation or removal period, roofing tasks performed, frequency and duration of exposure, diagnosis, jurisdiction and applicable filing deadlines.

Identifying a manufacturer, supplier, contractor or property owner does not automatically establish legal responsibility. Liability is case-specific and depends on product evidence, exposure evidence and governing law.

Some matters may involve asbestos trust funds, but each trust has its own product, exposure and medical documentation requirements. Eligibility is not automatic, and compensation is not guaranteed.

Exposure that occurred decades ago does not by itself determine whether a claim is timely. Statutes of limitation and other deadlines vary by jurisdiction and circumstances and should be reviewed individually.

Roofing Products Asbestos Exposure FAQs

Did old roofing products contain asbestos?

Some historical roofing products contained asbestos, while many did not. Product type, manufacturer and installation period matter.

Could roofing felt contain asbestos?

Yes. Certain historical roofing felt products contained asbestos. Product-specific evidence is needed.

Could roofing shingles contain asbestos?

Some historical roofing shingles and cement roofing products contained asbestos, while others did not.

Can roofing mastic contain asbestos?

Some historical roofing mastics and sealants contained asbestos. Color or appearance alone cannot confirm asbestos content.

Can cutting asbestos-cement roofing release fibers?

Potentially. Sawing, drilling, grinding or breaking asbestos-cement products can release fibers.

Can old roofing be identified as asbestos by appearance?

No. Age, texture and color alone are not reliable proof. Product records or qualified laboratory analysis may be needed.

What evidence can identify historical asbestos roofing?

Useful evidence can include labels, catalogs, specifications, invoices, contractor records, photographs, asbestos surveys, laboratory reports and coworker testimony.

Does working around old roofing automatically qualify someone for compensation?

No. Legal eligibility depends on product identification, asbestos-content evidence, exposure history, diagnosis, jurisdiction and other case-specific facts. Compensation is not guaranteed.
