Roof Sheet Leak Testing Methods

It is commonly referenced as the standard for flood testing roof systems.

Roof sheet leak testing methods.

This astm testing procedure utilizes a calibrated spray rack with specific water pressures nozzles and distances to wet a wall with water at the rate of five gallons per square foot per hour. The test method described is for tests with constant temperature and humidity across the specimen. This method is useful for detecting leaks on larger roof areas provided the membrane is an electrical insulator. This method utilizes the insulation property in combination with the fact that water is a relatively good electrical conductor.

Electronic leak detection eld is a non destructive diagnostic used to identify water leak entry and areas of trapped water within a flat or low pitched roof construction. Roof leak emergency 1 partially unroll or unfold enough heavy 6 mil polyethylene sheeting to cover the leaking section of roof from eaves. Astm e1105 and aama 501 2 test methods are good overall methods commonly used to test exterior walls sloped glazing and shallow pitched roofs to help identify leak sources. Using electronically charged bristles it is an non intrusive roof leak detection method can identify problematic areas with pinpoint precision.

In the united kingdom the method is called the electrical earth leakage technique. Flood testing to detect leaks and verify the quality of newly installed assemblies has a long history in the roofing industry. 2 place the sandwiched end of the plastic along the eaves. 3 sandwich the top end of the.

According to astm test method e1680 covers the determination of the resistance of exterior metal roof panel systems to air infiltration resulting from either positive or negative air pressure differences. Although often referred to as the wet test this method of roof leak detection can be used with or without the addition of water although the equipment used is different the method is fundamentally the same.
