A blow torch will dry the area and warm it, which helps with adhesion.
Just make sure the flame doesn't go down any gaps and set fire to
something inside the roof.

Hot air blower or even the wife's hair drier might be safer....

I've usually found hot air blowers to be fairly useless out of doors.

Helps if there is no wind:-)

Mine is reckoned to push out 1kW so soon blisters paint.

My 50mm gas burner is rated at 86kW :-)
