A core cut test uses a tool called a core cutter to extract a sample of a building s existing flat roof system.

Other methods of taking core samples include. Core samples may be weighed dried and re weighed to provide a quantitative measure of moisture content. Cutting with an ax knife and or insulation saw or with a reciprocating saw. For instance the crrel cutter saws a 2 diameter hole in the roof.

It is difficult and often impossible to determine the composition of a roof system by visual inspection alone that is without penetrating the membrane. Why do a flat roof core cut test.
