New roof coming Oct 07

Read info from GAF here:

You will be OK. You can get down into the 40's but 70 to 90 is best to make them pliable.

Thanks both for the link and assurance. I have been very uneasy about this and will sleep better.

Oct is no problem. Some people think they need high temps to seal, but apparently the sealing sticks well enough at low temps that they don't lift and eventually it gets hotter and they can seal even better then.

I imagine there is a fair difference due to the color of the shingle. I know for a fact that black roofs are appreciably hotter than white roofs, but I can't tell you the difference in actual degrees.

A good strong sunny day and a dark roof, they will seal down at 50F no problem. The surface temp of the roof gets WAY bhaigher than air temp on a sunny day.

Torch and not worrry in the same sentance????

Hope those aren't IQ scores for the installers...

I had a cousin-in-law that was a roofer. Yeah, they seem a bit high for their IQ.

My experience over the years with many home remodeling projects is that roofing subs are pretty much the bottom of the barrel- and that is one deep barrel with a lot of extra bottom....

There is a reason "hot roofers" are almost impossible to insure - and a lot of "cold roofers" around here I wouldn't trust with a torch on a roof - sorry you actually had the torch and worry in 2 separate sentances.

Anyway, the sun will warm up the shingles and stick them down on a cold sunny day.

If you need to warm shingles to lay them it's too darn cold to be on the roof anyway - buy I'd use a flameless heat gun

Roof is done. Needed 15 sheets of ply. Currently 83f. I am in a good mood. Allstate claim offered me 250 bucks. F*ck off.
