Hail Damage to Galvalume and Galvanized Steel Roofing

Galvalume and galvanized steel roofing cannot be fully evaluated by visual or low-magnification analysis to determine the extent of damage to a roof after a hailstorm.  Hailstone damage must be evaluated using scientific laboratory equipment, such as stereomicroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), optical emission spectroscopy (OES), and on occasion, Fourier Transform Infrared Spectroscopy (FTIR), to accurately determine the extent of damage to the roof in question.

Specific examples of the use of these instruments and techniques when evaluating hail-damaged roofs will be discussed in subsequent blog posts. J.E.I. Metallurgical is currently investigating several damaged roofs across the United States.
