A couple of weeks ago, I asked a question about how to operate a
chalkline in relation to putting new three-tab asphalt shingles on a
shed roof.
Got some great answers and my son and I went to work. Unfortunately, it
was much more work than I anticipated, and being a "40-something" mom
with an 18-year-old not too enthusiastic son as a co-worker, just
getting the bundles of shingles on the roof just about killed both of
us.
So, work has progressed quite slowly. However, the end is in sight. We
are at the top! We measured so as to adjust the last few rows of
shingles so that they end right at the top.
Perfect! Well, maybe not. This is a shed roof, basically a slanted
piece of plywood built on an angle with none of those fancy valleys,
ridges and other parts of a roof that we know nothing about. So, other
than cutting off parts of the three tabs at the end of each row, it has
been pretty simple.
Except, what do we do now. My son pointed out, just as we prepared to
start the last row, that half the shingle will be grey, the bottom half
with the tabs will be white and the "black tarry strip across the
shingle will also be exposed. And where do we nail it?
I did buy a piece of drip edge that will come up over the top of
shingle and I suppose we could nail right at the top, slop roof cement
where the shingle and drip edge will meet and go from there....will
that work.
But, hey, I'm a woman, it is still going to look ugly with the
half-half color and tar at the top, and with using the chalkline and
all throughout, we have otherwise a very "perfect" looking job. Of
course it took us some 12 hours so far for 8 bundles...
Any suggestions?

Congrats! Sounds perfect, so far. And whilst the son undoubtedly
complained to high heaven (it's in the job description of teenagers,
after all! :) ), down the road he'll be bragging and inside right now
he's as full of himself as can be...

Drip edge goes at the bottom, not the top, so don't use that here.
If there isn't a ridge vent (that is, if the two pieces of roofing meet
at the roof ridge), then lay the last rows at the peak w/ the proper
setback and, if necessary, trim to the peak.
Then, to finish, take the shingles and, starting at the end of the
house into the prevailing wind, turn them ninety degrees and lay them
over the ridge where there's an equal amount on each side. Use two
nails on each and a dab of roof cement under the top edge of the first
one. When you're done, you'll have a nice, single-color ridge w/ no
tabs showing.
If you will look at some other houses, you should be able to see how
this works.
If, on the other hand, there is/was a roof vent, post back and someone
can lead you through that as well.
Again, sounds like you made a good job of it!

Sorry, just realized what I wrote--start at the end away from the
prevailing wind so each course is covering the previous _INTO_ the
wind.
If you're in an area that doesn't have such strong winds routinely as
here, this isn't particularly important, but here we have lots of
(mostly south or southwest) winds for days at a time. So, if start at
the east or north end of a roof, the ridge shingles are then laid
"into" the wind....

You cut the tabs off a row of shingles, and nail them up individually.
(Actually, you usually cut the shingles right above the tar line, but
whatever works.) Yes, some spots of roofing cement here and there may be
needed, if a tab lands where there is no sticky spot. You cap the thing off
with premade ridge vent, or cap shingles, or (most people) with a bunch of
shingles cut in thirds, with the tops tapered so the next shingle hides them
At the end, you nail down a cut tab to cover the last light spot, and seal
the nails with some tar, and sprinkle some of the same granules you scraped
off an extra shingle into the tar spots to hide them. (Thy actually sell the
granules at the roofing store for big spots, but most people only need a
tiny bit.)
If none of this makes sense, google for 'basic roofiug', or go find a DIY
book, to see pictures. It ain't hard, just filthy and nasty.
aem sends...

previous posters must have missed that this is a shed roof, no ridge,
so no ridge vent and no ridge cap. go ahead and put drip edge on.
when you get to the top, cut the top of the shingles off and just use
the bottom half with the colored granules on it. if it works out that
you need just, say, and inch of colored shingle, then you will have to
make a judgement call about what looks best; the little strip or a bit
or black showing or an oddball row. nails will have to be exposed when
fastening this last row, but cover the nail heads with a small dab of
roofing cement (available in caulk tubes--one small tube will do it) if
you'd like. (bet you it doesn't leak even if you omit the tar).
