An accurate assessment of the waterproofing of new and existing roofs can save building owners hundreds of millions of dollars annually. The challenge for roofing specifiers is to choose the most effective waterproofing assessment techniques from the outside in.

The fact is that there is no single, simple method to accurately evaluate the ingress of water from the outer roof membrane into the interior of the building. This has led to confusion among specifiers about which method is most suitable for a particular type of roof and what information each test provides.

This dilemma has led the Roofing Industry Committee on Weather Issues (RICOWI) to review existing water detection techniques to identify the following:

• working methods;

• possibilities of the tests;

• test compatibility with different components; and

• advantages and shortcomings of each test procedure.

RICOWI’s Moisture Control and Green Committee led this research as the group focuses on moisture control issues and identifies specific performance metrics for roofs. The committee’s membership includes manufacturers, property owners and academics to ensure a diverse representation of the roofing community.
