ABSTRACT
As Peter Green reported in the February 1987 of Architectural Record: “Roofing may be one of the least rewarding aspects of an Architects design program, but it deserves undivided attention or else it can become the most conspicuous of the program’s shortcomings. (Unfortunately, buildings are often remembered in the industry, not for their design awards, but for their roofing litigation.)”
Water has long been our enemy. Alec Tiranti, in his Ten Books on Architecture quoted Leon Basta Alberti (1695):
For Rain is always prepared to do Mischief and wherever there is the least crack, never fails to get in and do some hurt or other. By its Subtlety it penetrates and makes its way, by its Humidity rot and destroys, by its Continuances loosens and unknits all the Nerves of the Building and in the End ruins and lays waste.
