Polaris experts have a vast amount of experience evaluating building materials for durability and performance-related issues. This includes structural materials such as steel, concrete, wood, and masonry, among others; as well as various fenestrations, cladding/finishes, and roofing materials. Polaris experts are well-versed in the material science associated with the behavior of these materials; and have a strong technical understanding of the material specifications and design/construction guidelines associated with these materials. With this knowledge and know-how, Polaris experts can identify material deficiencies, and distinguish between manufacturing defects, construction defects and/or design defects.
Polaris was engaged to evaluate a low-slope, single-ply membrane commercial roof for hail damage. As part of this project, Polaris performed a joint evaluation with the insured’s representatives. The roof membrane was visually evaluated for evidence of hail impact, including hail-related fractures.
With input from the insured’s representatives, roof membrane sample locations were identified and extracted from the roof for further evaluation, including laboratory testing. These roof membrane samples were packaged and shipped to Polaris’s laboratory. Polaris visually observed each of the roof samples under 10x magnification, performed light table evaluations, and conducted water column tests in accordance with ASTM D5635.
Based on Polaris’s onsite evaluation, no visible fractures were observed in the membrane. Additionally, based on Polaris’s laboratory testing, no tears or fractures were present in the extracted samples and the samples passed the water column tests. Polaris therefore concluded that the single-ply membrane at the subject roof had not been functionally compromised by hailstone impact.
