How do I pull roofing nails out of rolled roofing without tearing it up so I can lift it up and slide flashing up under it?
Need tips ideas and suggestions.

Wedge a little screw driver (or use the end of a crow bar that has the nail puller on it) under the head. You should be able to get the head high enough to get the hammer under it. Be gentle and you shouldn't tear it. By putting flashing under it, a little tear wouldn't hurt much.
