It's quite simple! First, you'll need to get a sturdy ladder and some extension cords. Once you're up on the roof, carefully attach the cords to the lights and then plug them into the nearest outlet. Make sure to test the lights before you climb down to make sure everything is working properly. Finally, make sure to secure the cords so that they don't fall off or get tangled. With that, you should be all set for a festive winter display!
