Roof Test Cuts

The deck type usually can be determined from underneath you may have to pop a few ceiling panels.

Roof test cuts.

Cutting with a knife saw combination is useful for cutting samples of 4 to 12 square. Core samples consist of cuts through the roof membrane down to the roof deck. The sample provides an absolute test of moisture content and location. Determine the moisture content of a flat roof system.

One or more test cuts can determine the materials and deck type. The core cut also permits the constituents of the roof system and their condition to be determined. A core cut sample provides a sample of these materials and how they are installed. In addition roof test cuts with a roof core cutter help identify any repairs that have been completed that would have an impact on insulation application or coatings such as asphalt based patches which can drastically alter plans.

It is difficult and often impossible to determine the composition of a roof system by visual inspection alone that is without penetrating the membrane. Using a knife to cut through the roof membrane and then an insulation knife or saw to cut through the subsequent layers allows for better examination of the roofing layers. The sample from a core cut test allows us to examine the moisture content of the flat roof system particularly that of the underlying insulation. A roof test cut uses a tool called a core cutter to extract a sample of a building s existing flat roof system.

Sometimes there are multiple layers of roofing systems. Larger samples can be done but takes a considerable amount of time.
