Asbestos roofs are secured in the same manner as non-asbestos roofs that use similar materials.
Asbestos was used as roofs for houses because it is fire-resistant, durable, and has good insulating properties. However, it was later discovered that exposure to asbestos fibers can lead to serious health issues such as lung cancer and mesothelioma, leading to its ban in many countries.
There is no requirement that asbestos-containing materials be painted white. Tops of roofs, whether made of asbestos or not, are often painted white because that helps reflect the sunlight and reduce the heat loading on the building interior.

Asbestos, when cut and broken, releases tiny, tiny fibers that float around like dust. When inhaled, they damage the lungs in a way that can develop into cancer.
Installing asbestos flooring involves less disturbance to the asbestos-containing product than does removal of asbestos felt roofing. Consequently the flooring installer probably has less exposure to airborne asbestos fiber than does the roofing remover, and therefore less risk of developing cancer.However, if a similar comparison is made between the flooring remover and the roofing remover, the greater risk falls to the flooring remover.

Asbestos exteriors on houses is usually in the form of asbestos cement or similar hard materials. The asbestos fibers in such materials is "encapsulated" and cannot be released into the environment unless the material is crushed or turned to dust in some other way, as, for example, by drilling or saw cutting. The only way asbestos can be harmful is if it gets into the body. The only way asbestos from asbestos concrete can get into the body is if it is released by turning the concrete material into some form of dust. Therefore, as long as you do not drill, cut, sand or otherwise break it up the material it is not a hazard. There is also the issue of what happens as the weather erodes the material. Tests on asbestos-concrete barn roofs in France some 20 years ago showed that the weathering process not only degrades the concrete, but also destroys the fibrous nature of the asbestos component. So no particular hazard there.
An asbestos square is a square of a material that contains asbestos in it.
Asbestos was chosen as a component in structural materials because of its relative abundance, its stability to chemical attack, and its ability to remain unchanged over a wide range of environmental conditions. Its fibrous shape also made it useful as a material to strengthen otherwise brittle materials like cement and tile. The very things that cause it to be a problem in the human body - its fibrous nature, and its immunity to chemical attack, were characteristics that made it useful as a building material.
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
There is no international symbol for asbestos.
High speed winds blowing over roofs of buildings can cause damage such as roof shingles or tiles being torn off, structural damage if the roof is not properly secured, and potential water leaks if the roof is compromised. It is important for buildings to be properly designed and maintained to withstand high wind events.
