My next door neighbor has a trilevel house and the siding on the top level is deteriorating at the point where it meets the roof of the middle level. What is the correct construction practice for this situation to prevent the problem in the future? Is this a place where flashing is required (from the ground I can't tell if any flashing was used) or was the siding just extended to close to the shingles such that water flowing down the roof would just soak up into the siding?
