This comes from a friend who gave me a list of topics that I had not come up with just yet... SO, staple or clip? First things first... what is meant by this? Attaching lights? Using staples rather than clips such as the all-in-one? I take it since I haven't heard anyone talk about staples, other than one thread where they talked about using anchors? to attach lights to the roof, that clips are the way to go. SO, if this is the case, which I believe it is... I also know that there are many different kinds of clips. Anyone care to go through the main ones and explain what the purposes are of each and how they work (how they attach to the shingle)? My guess... all in one... this clip has a place to "clip" in your lights to the clip for all types and strands. It is put on the shingle sort of in the same way as a paper clip with paper? One side goes on top and the other is on bottom? The bottom one has pressure put on it naturally by the shingle to keep it from falling off? I would think that the strand isn't that heavy to begin with so this is usually not an issue. I have seen clips that appeared to be done by removing the bulb, placing the clip over the socket(?) and then adding the bulb? I say this because by the pictures I don't see how the lights could fit through the hole provided. What other clips are there and what little tricks have you found to put them in tuff spots?
