If your old, bubble-type skylight is cracked or leaking, it might be time to start thinking about replacing your skylights. Older skylights weren't particularly good at weather resistance or energy efficiency.
The good news is that your skylights can easily be replaced with virtually leak free units. Look for skylights that offer a curbed design, which raises them from the roof surface, and be sure to buy the skylight's built-in flashing kits - which are specially designed to deliver a leak free installation. By following these tips, you will be able to easily replace the skylights in your home.
