What Is ASTM D7349 Roofing Fastener Seal Capability?
ASTM D7349 is a standardized test method used to evaluate the sealing performance of roofing and waterproofing materials around fasteners.
This technique provides a consistent, reliable method for assessing water penetration resistance at fastener locations, which are crucial points for potential leaks in waterproofing and roofing systems. Additionally, ASTM D7349 is intended to be used as a standardised performance evaluation technique in product specifications developed by ASTM or other consensus bodies.

Our ASTM D7349 Testing Procedure
Test Assembly Preparation
Roofing or waterproofing material is fastened to the substrate using a standard fastener.
1Water Column Setup & Conditioning
Assembly is placed on a water-filled container and conditioned at 4 ± 2 °C.
2Exposure Period & Removal
The specimen remains underwater for 72 hours, then is carefully removed.
3Inspection & Pass/Fail Evaluation
All areas are inspected for water presence, and results are classified as pass or fail.

ASTM D7349 Roofing Fastener Seal Capability FAQs
ASTM D7349 determines the capability of an asphalt-based roofing or waterproofing material to seal around a fastener penetration and prevent liquid water from passing through the material under specified test conditions.
The method is intended for asphalt-based roofing and waterproofing materials that are penetrated by fasteners during installation. It can be used for product specifications and comparative evaluation of sealing performance.
Fastener penetrations can create potential pathways for water migration. Testing helps determine whether the material can limit water movement at the interface between the fastener and the roofing or waterproofing material, supporting evaluation of water-tightness in installed systems.
No. ASTM D7349 is a qualitative test method. It evaluates whether liquid water transmission occurs at the fastener penetration under the defined test conditions rather than providing a numerical water-transmission rate.
Yes. The standard does not prohibit testing materials after conditioning intended to simulate environmental stresses and strains. This can be useful when evaluating whether fastener-sealing capability is maintained after specified conditioning procedures.
