What are the main problems with using metal?

Answer 1

Some consumers may be turned off by the sound of rain falling on a metal roof while others would consider it an added benefit. New technologies make noise reduction possible with metal roofing. Sound proofing techniques include structural barrier between the roof and the attic and the application of insulation and plywood to eliminate excess noise. Therefore noise should not be considered a barrier in choosing a metal roof.

Denting can be another concern with metal roofing, but only extremely large hail or flying debris is likely to cause denting, and even then it rarely jeopardizes the integrity of the roof or causes leaking. It should be noted that aluminum and copper products are more prone to denting than harder metals such as steel.

Answer 2

The disadvantage of metals with very high densities is that there are harder to change and harder to be manipulated. The other disadvantage means that the high density gives the metal extra weight.

Answer 3

Some metals are naturally found in the Earth but can contribute to poisoning. Mercury and lead are heavy metals that can be harmful to human health when exposed over long periods of time.
