Testing+Evaluation Services

Roof Investigation

We provide, in conformance with applicable listed standards, testing of existing building components and materials, including:

• Roof Moisture Survey using Infrared Thermography and Electrical Impedance scanning (incorporating elements of ASTM C1153 and ASTM D7954).
• Roof Membrane Integrity Mapping and Leak Detection using a DC pinhole detector (ASTM D7877).
•Deck Contour Mapping to determine “pitch to drain” using a laser level system.
• Withdrawal Resistance Verification of roof fasteners (ANSI/SPRI FX-1).

Roof cuts and gravimetric testing are required for full ASTM C1153 and ASTM D7954 compliance. Contour mapping requires roof cuts to reach deck. Roof repair may be required after withdrawal resistance verification testing.
