  2. CONSTRUcTIONCOMPLIANCE TESTINGStorm related roof damage assessmentsforensic investigationslitigation support

  3. Fm Global 1 – 52 Field uplift testsastm E 907 field testing uplift resistance of adhered membrane roofing systemsASTM E 1105 Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls

  4. NEGATIVE PRESSURE TESTING SIMULATING WIND UPLIFT PRESSURE TO VERIFY RESISTANCE OF LOW-SLOPE MEMBRANE ROOFS FM GLOBAL 1-52 ASTM E 907

  5. WIND WIND ACTS A FLUID FLOWING OVER AND AROUND STANTIONARY OBJECTS

  6. WIND ~ 25 psf WIND CAUSES A POSITIVE PRESSURE ON THE WINDWARD SIDE OF THE OBJECT AND CAN CAUSE A NEGATIVE (UPWARD) PRESSURE ON THE ROOF 25 psf

  7. WIND

  8. After the storm

  9. BUR - DELAMINATION Poor Adhesion Between Insulation and Cover Board Poor Adhesion Between Cover Board and Membrane Poor Adhesion Between Deck and Insulation

  10. Bur - DELAMINATION Poor Adhesion Between Cover Board and Membrane

  11. TPO - DELAMINATION Poor Adhesion Between Insulation and Membrane

  12. TPO - DELAMINATION

  13. BUR - fastener failure

  14. Before the storm… negative pressure testingCONSTRUCTION COMPLIANCE and risk assessment

  15. NEGATIVE PRESSURE TESTING

  16. NEGATIVE PRESSURE TESTING 5’ SQ Chamber Imposes an Uplift Force on the Membrane Pressure is Incrementally Increased to the Design Test Pressure Deflection of the Membrane is Measured and Compared to Performance Criteria

  17. NEGATIVE PRESSURE TESTING Fastener holding adequately at test pressure

  18. Application • Acceptance of new (including re-roofed and re-covered) above-deck roofing assemblies by FM Global…in regions that are both prone to hurricanes, typhoons or tropical cyclones and where design wind speeds are at least 100 mph (FM 1-52). • Field verification of adhesion of low-slope roof for the issuance of a certificate of insurability. For example WPI-8 for the Texas Department of Insurance (TDI). Negative pressure test

  19. Application • Risk Assessment – as part of the evaluation of a property this test could be used to determine probable loss at incremental pressure (Hurricane Strengths). Negative pressure test
