2 INTRODUCTION Inspection Procedures oinitial Inspection Report Visual Inspection Physical Sampling (Core and Slit Samples)

3 ROOF INSPECTION PROCEDURES Occurs upon project completion Includes visual observation and physical sampling

4 PROJECT INFORMATION The following documents are to submitted with request for inspection 1. Project specific specifications 2. SPF and Coating product manufacturer s installation requirements

5 ROOF INSPECTION The objective of the roof inspection is to determine the individual applicator s ability to apply SPF as required by the individual project specifications and/or manufacturers requirements.

6 PROJECT INFORMATION

7 ROOF SKETCH The Roof Sketch shall include the following: Initial Diagram Visual Findings Physical Sampling

8 INITIAL ROOF DIAGRAM Initial diagram of roof oarrow indicating DUE NORTH oarrows indicating slope odetails : edges, expansion joints, etc. openetrations : drains, pipes, HVAC equip, skylights, etc. otake photos and note on drawing w/arrow.

30 PONDING

31 COATING VISUAL INSPECTION COATING COATING BLISTERS POOR COATING ADHESION COATING CRACKS COATING RUNS PINHOLES

32 POOR COATING ADHESION

33 PINHOLES

34 POOR ACRYLIC COATING ADHESION

35 THIN COATING/EXPOSED FOAM

36 PHYSICAL SAMPLING involves destructive investigation and is necessary to ensure that the spray polyurethane foam roofing system has been applied according to the project and/or manufacturer s specification.

37 PHYSICAL SAMPLING CORE SAMPLES MIN 2 PER ROOF UP TO 10,000 SQ. FT. AND 1 CORE FOR EACH 10,000 SQUARE FEET OVER 10,000 SQ. FT. USE APPROPRIATE CORING DEVICE 2 DIAMETER MINIMUM

38

39 CORE SAMPLES CORE SAMPLES MEASURE TOTAL FOAM THICKNESS EXAMINE FOR: NUMBER OF LIFTS THICKNESS OF LIFTS ADHESION SUBSTRATE TO FOAM FOAM TO FOAM FOAM TO COATING COATING TO COATING

40 CORE SAMPLES OTHER OBSERVATIONS SOFT/SPONGY FOAM MOISTURE UV DEGRADATION BETWEEN LIFTS DIFFERENCE IN COLOR OF LIFTS COATING OR OTHER MATERIALS

44 CORE TESTING Cores will be measured and weighed to determine the unit weight in accordance with ASTM D1621. Unit weight will be reported in pounds per cubic foot (pcf) Cores will be measured and tested in compression in accordance with ASTM D1622. The compressive strength of the cores will be reported in pounds per square inch (psi)

45 MEASURE CORE

46 WEIGH CORE SAMPLE

47 COMPRESSIVE STRENGTH TESTING

48 CORE TEST RESULTS

49 SLIT SAMPLES SLIT SAMPLES OBTAIN SAMPLES FROM THE FOLLOWING: FIELD OF THE ROOF PASS LINES PARAPET WALL/ROOF EDGE (AT LEAST ONE SAMPLE) DEFECTS MINIMUM 3 PER 10,000 SQ. FT. SIZE 1/2 WIDE 2-3 LENGTH 3/4 DEPTH

50 SLIT SAMPLE EXAMINE SLITS IMMEDIATELY FOR COATING THICKNESS IF COATING IS THIN: TAKE ADDITIONAL SLITS IN A 5 RADIUS IN ALL 4 DIRECTIONS IF STILL THIN, ADDITIONAL SLITS IN A 10 RADIUS OR UNTIL ADEQUATE COATING THICKNESS IS FOUND MEASURE TOTAL FOAM DEPTH

51

52 2 TO 3 ¾" SLIT SAMPLE

53 MEASURE FOAM THICKNESS

54 OPTICAL COMPARATOR AND SLIT

55 SLIT AT BLISTER DEGRADATION OF FOAM
