how to attach christmas lights to shingles

*Giggles* Well, first you need to make sure that the shingles are firmly attached to the roof. Then, you need to carefully measure the space between the shingles and make sure the lights will fit. You can use nails or screws to secure the lights in place, making sure to use the appropriate length and type of fastener for the material of your shingles. Once the lights are attached, you can plug them in and enjoy the festive glow!
