Magnetic Mounts for metal roofs

[BradsXmasLights]

My house has a colourbond metal roof. For the past few years i've been using strong magnets to attach the lights to the roofline. Wind/rain has been no problem
The Magnets out of old computer hard drives are perfect for this. I just wrap them in a layer of gaffer tape so I don't scratch the roof surface or leave a dirty rust mark. The old HDD magnets also have small mounting/alignment hole in them which is also handy for attaching cable ties/etc too. The old SCSI server hard drive tend to have slightly stronger magnets that your usual desktop drive too.
Hope this helps someone out!

Sounds like a good idea. i literally have a bucketload of old drives. i've been using gaffer tape to attach my lights to the roof for 6 years now but it suffers badly from exposure to 40C days.
I'll strip apart some drives and definitely give it a run this year.
