— One of the fundamental purposes of a home is to shelter its residents from wind and rain. But a $1.8 million house overlooking Sarasota Bay that Zirkelbach Construction built for Govin and Padmini Rajan in 2002 has never done that completely. From day one, the roof has leaked, and it has continued leaking ever since -- all over, and into the top floor of their three-story, contemporary dwelling. The constant dripping has caused more than $1 million in damage to the pinkish-brown granite floors the Rajans had imported from their native India.
