I was sitting in traffic today, and I was imagining what I would do with different buildings along the road. I came up to a bank and it hit me... there were no gutters and the shingles just hung off the edge. How do you clip the lights to these? Just go straight on the shingle with the tab facing the pitch of the roof? The part hanging off the edge? Are the clips strong enough to hold that? ALSO, I take it your clips go on each light so to keep them straight... I wasn't sure about this for a minute, remember I have never done this, and then common sense kicked in. I have so much going on right now that I can't keep things straight some times. SO, for future reference... sorry in advance for any DUH! questions.
