If the shinglesare not considered a health hazard then they do not have to disclose it. Only when there is a solid reason then they have to do so.
Some concrete shingles did contain asbestos. Many shingles never were made with asbestos.

NEVER attempt to remove asbestos yourself. It is fine until it is disturbed and so you should always contact a professional to fully remove it safely. Your council should be able to arrange this for you.

There are two types of asphalt shingles: fibre-glass and paper, though paper are less common due to being a fire hazard. Alternatives include wood, slate and asbestos-cement, though again the latter has proven to be a health hazard and is no longer used.
Roof shingles were invented by early man to improve the livability of shelters. They may have consisted of leaves, thatch, then progressed to slate slabs, split wood, and tile, then evolved into metal, asbestos, and asphalt, and now include concrete and rubber products.
Since three bundles are required to cover 100 sq feet. (based on three tab organic shingles) and each package holds 21 shingles, then the result is 63 shingles, four nails per shingle, or 252 nails. Add about 10% for items such as trim and you shouldn't be far wrong

Hi, do you mean how many bundles of shingles would be required for a 40 x 20 roof?
The dampness of the house may contribute to children's asthma by encouraging the growth of mold. Asbestos does not contribute to asthma. Although several forms of cancer are caused by asbestos, the asbestos fibers must get into the body for that to happen. If the asbestos material in the house is in good physical condition and is not disturbed, then exposure will not occur. This might be the case if the asbestos is in roofing materials, shingles on the outer walls, or in floor tiles. If the asbestos is in insulation on pipes or the heating plant, those materials are more likely to be converted into dust by children playing or by adult uses such as placing hangers on the pipe insulation. In those cases a professional should be brought in to assess the hazard and suggest approaches to eliminating or controlling it.
