how to put christmas lights on roof without ladder

To put Christmas lights on the roof without a ladder, you can use a telescoping pole with an attachment that holds the lights in place. This will allow you to reach the roof from the ground without having to climb up. Alternatively, you can use a long-handled pole that has an attachment that grips the lights and allows you to push them up to the roof. You can also use a hook on a rope to pull the lights up to the roof, or you can use a drone to drop the lights on the roof.
