Standard Test Method for Determining Water Migration Resistance Through Roof Membranes
Also Known As:
The ASTM D7281-07 (R2013) standard provides a means of evaluating the resistance of roof membranes, seams, and laps to water migration from standing water on the roof. The standard evaluates the performance of roof membranes in their initial state as well as after simulated deterioration caused by the ultraviolet energy from the sun.
This test method specifically applies to various types of roof membranes, including built-up roof membranes, modified bitumen, and single ply roof membranes. It aims to determine the potential for water leakage through the roof membranes when subjected to a standing head of water and pressurized with air from the underside.
By conducting this test, manufacturers, contractors, and building owners can assess the effectiveness of different roof membrane materials and constructions in preventing water migration, which is essential for ensuring the durability and performance of roofing systems. Compliance with this standard can help in selecting suitable roof membranes for specific applications and in maintaining the integrity of roofs.
