Asbestos-cement roofing & siding history:

This article gives a history of the production & use of asbestos cement roofing & siding products. We include research articles as well as patent citations that help trace the use of asbestos cement in and on buildings from the late 1800's to the present.

In the cement asbestos siding article series listed below, we provide photographs and descriptive text of asbestos insulation and other asbestos-containing products to permit identification of definite, probable, or possible asbestos materials in buildings.

History & Age of Use of Asbestos-Cement Siding & Roof Shingles

Hatschek machine for cement asbestos  shingle or sheet production at  InspectApedia.com The Rosato text cited below and our research article and patent search on asbestos cement shingles and siding give insight into the history of and development of cement-asbestos shingles, siding, and cement board used on and in buildings. Cementious siding and roofing such as fiber-cement siding, lap siding, and fiber cement roof shingles containing asbestos may then have appeared on homes constructed between 1906 and 1980 in North America and continuing later in some other countries.

At CEMENT ASBESTOS PRODUCT MANUFACTURE we provide a more-detailed history of the development and use of asbestos in building and other products. There we describe the Hatschek Machine for Production of Asbestos Sheet Goods.
Excerpt:

It was not until 1907 that the invention by an Austrian engineer, Ludwid Hatschek, made possible the manufacture of pre -formed asbestos-cement products. The Hatschek machine, a wet transfer roller, was used to produce the initial asbestos-cement sheets, while two other manufacturing processes included the Mazza process for pipes, and the Magnani semi-dry process for corrugated sheets. - Woods (2000)

We learn further from patent citations that asbestos-cement products were in use in the U.S. before 1910, as inventions often cite improvements to existing designs and that an explosion of patents and products making use of asbestos-cement ensued between 1907 and 1940. The improved fire-resistance of cement asbestos roofing led to its recommendation in the U.S. by the National Board of Fire Underwriters in 1920. (National Board of Fire Underwriters 1920).

A similar-looking product, composite siding made of asphalt-impregnated fiberboard was also used for lap siding and wall shingles but is not an asbestos-cement product. See SIDING TYPES, INSTALLATION, DEFECTS for a guide to siding products of various types.

Question: when was asbestos cement siding first used?

Corrugated asbestos cement building siding in New York City (C) Daniel Friedman2016/09/08 Gary said:

In what year did they start to use asbestos in cement siding ?

This question was posted originally at ASBESTOS DISPOSAL REGULATIONS

Our photograph at left illustrates that corrugated asbestos cement (or on newer buildings corrugated fiber cement) panels are also used as siding, not just as a roofing product. This building was observed in New York City and based on its age, we suspect that the material shown is asbestos cement corrugated siding, not a newer fiber cement product.

Reply:

Gary, a reasonable guess for the start of widespread use of asbestos cement siding in the U.S. would be 1920, but patent disclosures and other research make clear that such products were in development and use one or two decades earlier.

The earliest use of asbestos in modern building products that I found was discussed in a Scientific American article published in 1876 and cited below. Asbestos researchers note that human interest in the properties and uses of asbestos is more than 2000 years old.

The following citations giving a history of the use of asbestos-cement in building products are arranged chronographically, rather than alphabetically - Ed.

Really? What's the likely level of hazard from cement-asbestos roofing or siding? The risk of high levels of airborne asbestos from cementious products is probably very low unless the workers are using power equipment like sanders and saws or power washers on these substances.
