I have to do some repairs on a garden shed. I need to take off about 5
rows of shingles and replace
one of the roof boards on the bottom edge.

Now, when I put new shingles on, should I:
1) Re-shingle over the entire roof, meaning that the bottom rows go on
the new wood, and then I cover the remaining shingles as I move up the
roof, which will leave a bump.

or

2) Just re-shingle up to the remaining good shingles, and push the new
ones under the old ones.

Since it's a small roof, the cost and time for shingling are not an
issue. But I don't want to rip up any more old shingles.

TIA,
Jim

strip all repair deck replace all the shingles.

do it once do it right then go relax..........

Just reshingle what you have to remove as you state. Why completely
reoof unless necessary?

On a small shed you should be able to manage a complete tear-off. That
is how to do the job right especially since the shed is small.

It can be done, but it won't be easy or likely pretty. When you have
removed enough to fix what is broken, try to slip #30 felt under the
old (easier if the old is #30), tack it down, start from the bottom as
if doing a new roof, work up to the old, slipping under between the
felt and shingles, you may have to gently wonder-bar a few nails out of
the old or cut them off with side cutters, you will have to drive nails
from the top to lock down the final course, and tar the heads (hint:
tree pruning spray)

You could TRY sliding new shingles under the edge of the old ones,
but if they're anywhere near the end of their life, they'll
just crumble and you'll end up replacing them anyway.

best reason so it all matches.

say the existing shingles are 1/2 thru their life......

in not too many years you will be replacing shingles that arent that
old.

go to sell your home and it will be a big hassle.
