   Ditto with Stephen (and he's a pro roofer) I would add that if they are concerning you now, you could take some roof cement and seal them down, you could take a heat gun up there and soften them up a little, see if that helps, just don't hold it in one spot too close too long!

   Put new shingles on a new roof a couple of weeks ago when the temp. was about 40 degrees Farenheit. I used Owens-Corning Oakridge 30 year fiberglass ( http://www.owens-corning.com/owens/around/roofing/shingles/SelectedStyle.asp?Shingle_Line=Oakridge+30 ). There are about 10 shingles that have curled edges. They are mostly in a row so I think they came out of the bundle that way (although I didn't notice it at the time). Temps here went into the low 60's last week. I thought that would be enough to get them to lay down, but they didn't. The question is: Can fiberglass shingles take a permanent set or do I just have to wait for summer?

   *Jerry, I can't say if your shingles will eventually lay down flat or not with out seeing them. In my area(NE Ohio) 60* at this time of year would not be enough to seal them down. Generally I find for complete seal down I need temps in the 70's with full DIRECT sun. Even an air temp in the 70's right now would not help much cause the sun is to low on the horizon to be considered DIRECT. If they do eventually lay flat it probably won't be till much later in the spring. If the bend is severe enough the mat inside the shingle is probably damaged and I doubt the shingles will lay flat even in the 90's. The edges of the shingle were probably damaged somewhere in transit from the factory to your roof top. The best thing would be to replace those 10 or so shingles.Good Luck,Stephen
