Forensic Investigations

Destructive Testing
Destructive testing involves taking a core (test cut) sample of the existing roof system. Extracted test cuts are used to determine the construction and moisture content of the existing roofing system.

Water or Flood Testing
During a leak investigation, water tests are commonly used to test the roof with controlled water sources in order to find the location of the leak source.

Visual Inspection
A professional roof technician performs an inspection of the entire roof system including the top membrane, flashings, metal edges, wall copings, gutters and any problem areas you have.

Laser Survey
Laser surveys may be conducted to asses the slope of the roof to aid in identifying what may be causing the existing ponding conditions

Electronic Leak Detection
Electronic Leak Detection (ELD) provides a way to identify and pinpoint a leak or breach in the waterproof membrane. The ability to identify a leak and where the leak is originating prior to the overburden or re-roof can save thousands of dollars in damage prevention and construction costs.

Infrared Moisture Survey
Infrared moisture surveys provide a way to identify specific areas of wet insulation and moisture that is present in the existing roof system. A leak into a waterproof membrane often enters into the roof system and saturates the insulation and underlying layers.

Capacitance Testing
Electric capacitance testing is used to determine if a specific roof area is wet or dry. These are commonly used on leak investigations for small isolated areas. Limitations include EPDM and aluminum coated roofs. Deck scanners can be utilized for larger projects.
