This series discusses forensic use of infrared thermography to detect construction defects. We started off discussing 10 Ways to Use Infrared Imaging to Detect Construction Defects. Here is the first of those ten:
Ice Damming is when snow or ice collects at upper roof sections, melts and flows to cold eave sections and then re-freezes. It damages both the inside and outside of buildings and can become a safety issue.
Many construction companies use "cold roof design" to prevent or reduce ice dams. A cold roof design provides consistent cross-flow ventilation, resulting in temperature equilibrium. By maintaining a roof temperature that is closure to the outside ambient air temperature, ice damming is significantly reduced because "hot spots" are reduced.
Infrared thermography evaluates deficient conditions in cold roof construction. Measuring changes in temperature can indicate where repairs needs to be made or where construction has been faulty, perhaps due to missing metal rim plates or defects in the ice and water protection membrane of the roof.
