We use both—clips first, staples only when necessary. Our standard approach is to install lights with professional, high-quality plastic clips wherever possible. Clips are non-damaging, secure, and designed for long-term outdoor use. For peaks, corners, or other spots where clips cannot hold securely, we use tiny staples sparingly for added safety and stability. We also carry specialized magnetic clips for metal roofs or metal structures, so we can safely attach lights without drilling or permanent fasteners when a magnetic solution is appropriate. If you already have clips you prefer, we’re happy to use them to install your lights. If you don’t have clips or want us to supply them, just let us know and we’ll provide the correct type for your roof and lights. If you’d like, tell us your roof type (asphalt shingle, metal, tile, flat, etc.) and the type of lights you’re using, and we’ll recommend the best clip option.
