In doing some other work, I have managed to damage one tab of the shingles in the middle of a porch roof. It really ought to be replaced. These are standard 3-tab fiberglass shingles.
Question: is there some way to extract that damaged piece and replace it, or must I rip up a “V”-shaped section up to the top of the field of shingles? The porch roof below this damage is not “finished” — it is painted beadboard, not plaster of drywall, but I really don;t want it to leak even though the damage would not be severe if it did.
Thanks

You should be able to gently pry up that shingle by bending up the two above it. In summer when they are warm it is easier to do without damaging them, so you are in luck there. If you can't get the nails pried out, you can get a special tool that goes under the heads from above and you hammer down on a "step" in the tool and it yanks the nails down and out (getting the new nails in is another story). Just be careful not to break off or tear the shingles above during this operation. If nailing the replacement is too difficult, you could probably get away with using tar to stick it in place. The tar (adhesive strip) on the shingles above will also get heated by the sun and help hold the new shingle in place.
i do it all the time... (use to anyway on the shopping center i just sold) i'd walk the roof and replace damaged shingles... it was at least 15yrs old but still looked good... but it covered 25,000sf and i wasn't up to put'n on a new roof... so everytime i was on the roof i'd walk it looking for nail pops and broken shingles... with about 15 3 tab shingles every 6mo or so i could keep the roof looking good and sound...
the tool that was mentioned is an almost must have slips under and hooks the nail and rips it out... if it's hot out you can get under it to renail... but most of the time if i could get 2 nails in and some tar under it i was happy (tar in a caulking gun is what i'd use with a piece of plastic tube to extend the tip out 8"...) BUT 9 out of 10 times i'd be replacing 1 tab...yep i'd cut and replace one tab at a time... i'd get 3 repairs out of one shingle... alot faster and if done with care and a couple beads of caulking gun tar... i could make 20-30 repairs in about 90 minutes...

Bob,
Best done on a mild, cloudy day. The sealing strip between the shingles is much easier to "pop" apart if the roof is cool. Ideally, it will be cool enough to allow the sealing strip to separate, but warm enough so that the shingle is somewhat flexible.

And/or... just drag a hose up there to cool the shingles.
Yep, been known to do that although if the sun is out, it takes a whole bunch of water.
Thanks everyone for your encouragement and ideas.
