The exterior cedar siding on my house rests on an approx. 1 inch ledge. The joint between the two isn't calked. The inspector who inspected our house before I bought it said this was a good thing because any moisture accumulating behind the cedar would drain. I just hired a painter to repaint the house and he said this joint should be calked. This house in Ohio is 36 years old and is in good shape. Who is right?
