cool or hot

Are shingles easier to lift without damage in cool (40s) or hot weather?

I would say hot weather. The shingle and the glue are both softer when it's hot.

On the other hand, cold weather will tend to "snap" the tiles loose as opposed to the glue peeling away trying to hold together.
Seriously, the best thing is do it at a temp that you will feel most comfortable with. Its hard work. I also suggest a roof shingle removal tool. They run about $25 or so. Available at most home improvement stores.

I should have mentioned I'm trying to lift them temporarily to install step flashing during siding replacement. Using one of these:Name:  image_18374.jpg

step flashing

Any alternative suggestions for what I'm doing?

Replacing sheet T1-11 siding. Old (rotted) siding at a roof to wall juncture is glued to the old continuous steel flashing with roofing cement. The flashing was installed over the siding. I need to remove the siding and the plan was to gracefully and quickly disengage it from the flashing, slide the old flashing out from under the roof shingles, replace with aluminum step flashing, put the T1-11 over the flashing, and re-adhere the shingles to the flashing and each other.

I have a limited window of time to do this in and it's getting complicated lifting the old shingles Shingles threatening to break, and I'm not sure it'll be easier in hot weather.

I'm wondering about NOT replacing the flashing (assuming I can get the remaining old siding off the back of it), putting up a new flashing overlapping the old flashing down only to the level of the shingles (not under the shingles), and sealing the new flashing to the shingles - or at least to the old flashing.

Make any sense, or any other ideas?
