Why do a roofing core cut?
A core cut is a roof sample of all layers of the roofing system down to the roofing deck. It can provide design information, identify any hazardous materials, the presence of wet roofing components and will identify all materials in the composition of the roof and may allow roofer to determine the current age of the system. It also provides the roofing company information on whether any existing layers can be salvaged.
