Asbestos cement
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.
