how to attach xmas lights to roof

Well, son, that's a great question! First, you need to make sure your roof is clear of any snow or ice, and that the surface is clean and dry. Next, measure the length of lights you need to cover your roof, and cut the string of lights to size. Finally, use a staple gun to attach the lights to your roof, being careful not to damage the shingles or other roofing material. You may need to use an extension cord to reach the areas that are hard to reach. If you have any questions, don't hesitate to ask!
