ABSTRACT
We were asked to investigate the roof on a “cooler” building (where the ambient interior temperature is kept at or below 4 °C [40 °F]) that contained food for distribution to local super markets. During the winter months, the tenants complained of almost constant leakage through the roof and sporadic leakage (during or shortly after rainstorms) the rest of the year. Leakage is a very serious problem for this food distributor, since the Board of Health could force them to cease operations until the leakage was halted.
