A Method to Detect and Locate Roof Leaks Using Conductive Tapes

Apr 12, 2010

Undetected roof leaks and the subsequent deterioration are considered the greatest cause of premature roof failure. This paper describes a method whereby a leak locating grid of conductors is placed on the top of a roof membrane to detect and localize leaks to within an area defined by the grid spacing.

The method is particularly useful for roof designs that incorporate a waterproofing membrane under a green roof, wear-course or topping slab where direct inspection of the roof membrane is difficult or impossible. A top-of-membrane grid system can provide an accurate and cost effective method to monitor and maintain a wide range of covered roof types and sizes. The initial mock-up testing as well as examples of subsequent field installations is provided.
