How do I install C7 and C9 lights strings on a flat roof?

There are several ways to install lights on a flat roof - staples, tape, etc - but you might consider using these commercial grade clips tailored for use with traditional C7 and C9 Christmas light cord cords and bulbs. (If you are installing on a metal roof, you should also take a look at our magnetic clips.)

These clips are not for use with plug-and-play LED light strings or mini lights since they hole the light strands by snugging in around the area where the screw-in bulb meets the socket. Other styles of lights are too small to be held effectively.

These clips can be secured with your small nails or screws or adhesive silicone.

Customers for these clips include commercial installers, hospitals, malls and old-time theaters.

Made of high grade polycarbonate, this material is our most durable clip fabrication but like all manufactured clips is not designed for long term installation and carries a 90-day seasonal use warranty.


Please test your lights when you receive them! Everyone is happier when we resolve issues quickly.
