This one probably more to the vets. I have a client I picked up this year, 287' c-9 mounted on the roof. The trick, its a diner, 50's retro look, highly polished aluminum flashing for mounting point. The owner was against para-pit clips and shingle tabs, so I went with hot glue. Now the kicker, we get this freak 14" snow storm last week, followed by another 6-8" two days later. Well long story short, the snow slides down the roof a bit - couple feet, and wacks off about a dozen and a half or so lights. By Monday all the snow we have here should be long gone Not that I am going to do anything different other than re-glue them at this point, but for next year, should I stand firm on the para-pit slips, or take my chances again with the hot glue??
