The Goetsch-Winkler house in Okemos, Michigan, one of Frank Lloyd Wright’s most successful Usonian designs was in need of roof repairs. Built in 1939, it was experimental in its construction, and it has undergone several repairs – the first in 1957. There were three areas of concern; however, only the first two were addressed due to the modest budget. First, the framing for the south-west facing studio windows was considerably out of plumb. Second, the tar and gravel roof showed cracks and some leakage and considerable sag was noticed in the cantilevered roof over the carport. Third, the brick foundation for the garden wall showed deflection and some cracks.
