Failures of basic building functions can range from defects in single components, such as windows, to extensive deficiencies in an entire exterior wall system. Building deficiencies such as water infiltration, excessive building movement, or premature component failures have become more common as buildings have become more complex. Exponent has performed comprehensive and multidisciplinary programs investigating and testing both exterior and interior building components. Standard, specialized, or custom-designed inspection, laboratory testing, and analysis programs complement our expertise. Moisture penetration Failures of roof systems occur more frequently than failures of any other aspect of building enclosures.
Exponent has extensive experience investigating roof failures on both flat and sloped surfaces.
In addition, our expertise with roof systems includes knowledge of material performance and the interaction between the roof and other building systems. Such testing can be used to determine the quantity of air and water infiltration. Testing has also been used to measure the thermal performance of building components. Exponent's architects, engineers, and scientists also have extensive backgrounds in the areas of wood research, design, and construction. We have experience investigating failures of virtually all aspects of wood construction.
