Original Air Date: Week of January 17, 2008

General contractor Tom Silva helps a homeowner replace a skylight that is leaking water down into the kitchen below. Then Tom, along with host Kevin O'Connor, plumbing and heating expert Richard Trethewey, and landscaping contractor Roger Cook ask, "What is it?" Afterward, electrician Peg Preble shows Kevin how to troubleshoot and repair a faulty 3-way light switch.

How to Replace a Leaky Skylight

Tom helped a homeowner with a skylight that was leaking water down into the kitchen below. Up on the roof, Tom determined that the skylight had been flashed correctly, but that the gasket between the glass and wooden frame had deteriorated and failed. Rather than try to repair the unit, Tom decided to replace it. They started by removing the asphalt roof shingles surrounding the old skylight. With the shingles removed, Tom used a utility knife to cut through the flexible flashing, unscrewed the brackets holding the skylight to the roof decking, and pulled the skylight free. Next, Tom installed the "trim kit" around the opening and set the new skylight in place, being careful to center it precisely on the opening. Tom then secured the unit with ring-shank nails. To make the new skylight watertight, Tom Installed the metal flashing kit, which included a top and bottom piece and step flashing for the sides. Before installing the step-flashing, Tom installed self-adhering flexible flashing up the sides of the skylight for extra protection. Finally, the remaining roof shingles were reinstalled and the installation was complete.

How to Repair a 3-way Light Switch

Kevin and electrician Peg Preble troubleshoot and replace a faulty 3-way light-switch. Peg begins by explaining how a 3-way switch system works. To fix the problem, Peg first removes one of the switches. To test it, she uses a "continuity tester" and confirms that the switch is broken and needs to be replaced. She replaces it, being careful to attach the wires to the same terminals as before, and the repair was complete.

Continuity testers and replacement light-switches are available at most hardware stores and home centers.
