The short answer: A metal roofing maker says to use magnets: magnetic clips, magnetic hooks or lights with magnets built in. Do not screw into the panels (holes can leak) and do not use adhesive (it can remove paint and void warranties). Metal roofs can be slippery, so have a spotter or hire a pro.

Safety first. Use only lights and cords rated for outdoor use, plug them into a GFCI-protected outlet, keep ladders and light strands at least 10 feet from overhead power lines, and have a helper. Hire a licensed electrician for any wiring or new outlet. See our safety guide. This reminder is ours; the sourced details are on that page.

What a metal roofing maker says

McElroy Metal, a metal roofing company, gives this advice on its blog.

Use magnets. Magnetic clips, magnetic hooks, or lights with magnets already built in. It says magnets grip the roof without scuffing or scratching the panels.
No screws. "Holes = leaks," it says.
No adhesive. It says adhesive can remove paint and void warranties.
Snow guards. If you get snow, it recommends a snow guard system, to prevent rooftop avalanches that could injure people or damage lights.
Slippery. It says metal roofs can be slippery and recommends a spotter on the ladder. If you do not feel safe, have a pro hang the lights while you supervise.
Power. Check that outlets and cords support the lights, and use outdoor-rated cords.

Our notes

Magnets only stick to steel and other magnetic metal. We did not find a source on this, so test a magnet on your panel first.
We did not find an independent source on magnet strength, wind or snow load. Check clips after storms.
Check your roof maker's warranty before you attach anything.

Read the ladder rules first. For steep or high roofs, see hire an installer or DIY. Roofs with shingles or no gutters: without gutters.

Need clips or a hanging pole?

Clips made for the job are gentler on your gutters and cords than nails or staples. Match the clip to your gutter, shingle or trim.
