Dean Sharp opens the second hour with a “haunted” light switch mystery, explaining why intermittent contact—not the switch or ceiling fan—is likely the culprit, and how an electrician can track down the problem. A follow-up caller offers a theory, but Dean rules out a three-way switch issue before moving on to a fence problem in windy Lancaster, diagnosing rotted, improperly treated posts as the root cause. The call-in streak continues, wrapping with advice on how to tell when it’s time to refinish a roof and the key indicators that determine the right timing for the job.
