ASTM E907 and FM 1-52 field uplift testing are methods used to evaluate the wind uplift resistance of installed commercial roofing systems. These tests help determine how well an adhered roof membrane and its supporting assembly can withstand negative pressure similar to the forces created by strong winds and storms.
For commercial buildings in wind- and hurricane-prone areas such as Florida, field uplift testing can provide valuable information about the actual performance of a roof after installation. ASTM E907-25 is currently the active ASTM standard for field testing uplift resistance of adhered membrane roofing systems.
How Does Field Uplift Testing Work?
During a typical field uplift test, a test chamber is positioned over a section of the installed roof. A controlled negative pressure is created inside the chamber to simulate wind-induced uplift. The test evaluates the roof assembly’s response as the applied pressure increases.
The test can identify failures involving the membrane, adhesive, substrate, insulation, or other components of an adhered roofing assembly. ASTM E907 specifically applies to adhered roof membranes installed over different types of substrates, including assemblies with adhered or mechanically fastened cover boards, rigid insulation, or base plies.
The objective is not simply to determine whether the membrane itself is strong. It helps evaluate the performance of the installed roofing assembly and identify where failure may occur.
What Is ASTM E907?
ASTM E907, formally titled Standard Test Method for Field Testing Uplift Resistance of Adhered Membrane Roofing Systems, is an ASTM International test method for evaluating uplift resistance in the field.
The current edition is ASTM E907-25, which was approved in late 2025. The updated standard replaced the older versions and remains the active ASTM field test method.
ASTM E907 can be used on newly installed roofs and, in appropriate circumstances, to help assess existing roofing systems. For new construction, ASTM recommends conducting the test relatively soon after installation so that aging, weathering, or service conditions do not influence the results.
What Is FM 1-52?
FM 1-52, associated with FM Global’s Property Loss Prevention Data Sheets, is titled Field Verification of Roof Wind Uplift Resistance. It provides procedures for verifying roof wind uplift resistance in the field.
FM 1-52 includes field uplift testing procedures, including bonded uplift and negative-pressure testing. In its negative-pressure approach, a test chamber is placed over a roof section and controlled uplift pressure is applied.
However, roofing professionals should be aware that ASTM E907 has been updated. Industry guidance published in 2026 recommends using ASTM E907-25 rather than older ASTM E907 editions, and questions have been raised regarding the continued use of FM 1-52’s deflection-based criteria.
Why Is Field Uplift Testing Important?
Field uplift testing can be useful when a building owner, project specification, consultant, insurer, or authority requires verification of roof wind resistance.
It can help:
- Evaluate the installed roof assembly’s uplift resistance
- Identify potential adhesion or substrate failures
- Verify installation quality in specific test areas
- Investigate existing roofs after severe wind events
- Provide field performance information beyond laboratory testing
It is particularly relevant for commercial roofing in Florida, where hurricane-force winds make wind uplift resistance an important consideration.
ASTM E907 vs. FM 1-52: Which Should Be Used?
Although ASTM E907 and FM 1-52 have historically been used for similar field uplift evaluations, they are not identical standards. Project requirements, roofing specifications, insurance requirements, and applicable authorities should determine which procedure is required.
For current projects, roofing professionals should verify the applicable edition and testing requirements rather than automatically relying on older references to ASTM E907 or FM 1-52. ASTM E907-25 is the current active ASTM standard for field testing uplift resistance of adhered membrane roofing systems.
In summary, ASTM E907 / FM 1-52 field uplift testing is a controlled roof test designed to evaluate how an installed roofing assembly responds to wind-like uplift forces. Properly performed testing can provide useful information about roof adhesion, assembly performance, and potential failure points—helping commercial property owners make more informed roofing decisions.
