Small -- 4x6 +- wooden "eyebrow" or overhang on back porch (S. exposure).
Have to replace old worn cover (what we used to call "tar paper".
Any difference between individual shingles and sheet, in terms of wear?
I assume ease of replacement better with indiv. shingles, but cost of installation higher?
Your wisdom appreciated.

Probably what they call "rolled roofing" around here. It is a cheap roofing material, basically a giant rolled-up shingle, a heavy asphalt backer with fine aggregate embedded. Not as durable as shingles, but certainly more durable than 30lb felt.
If you're talking rolled roofing, individual shingles are much more durable.
I would want this eyebrow or whatever the hell it is to have a roof that matches the rest of the house.

Shingles and sheet of what? Hard to believe that the roof just
has tar paper on it now. What's on the rest of the house? You
would think the porch would have the same roofing, unless the
porch roof is too low pitch and has rolled roofing, ie hot tar
type which is usually used on flat roofs. What is the pitch?
I doubt there is much difference in the cost of doing a porch
roof either way. But if it has enough pitch for shingles to be
used, then rolled roofing is going to look like hell.

Roll roofing over an adhesive vapor barrier like used along drip edges.

OK, here is pic to show angle of "eyebrow" roof on back porch.
Hope this will help recommend shingles vs ??
Also: must shingles be underlaid with ? specific name of product?
Thanks for the photo. I was surprised because when I read "eyebrow" in your
original post I was thinking of the curved type of eyebrow roof structure.
If you go to Google Images at http://www.images.google.com and do a search
for ---> eyebrow roof <--- you'll see what I mean.
So, what you have is an overhang over a porch with a flat pitched roof. And
the pitch is enough that you have a choice of using individual shingles or
roll roofing or other options.
It would probably help if you posted a photo of the existing roof so people
could see what is there now, how it connects to the house, etc. And, if the
photo (or another photo) could show another part of the roof for the rest of
the house, people could get an idea of whether to try to match that style
etc. With a better photo or two of the actual roof, people here could also
let you know if you need drip edge etc. I know a little about that, but not
as much as others here.
Are you thinking of doing this yourself or having someone else do it? That
could make a difference also in terms or which roofing materials you may
want to use.
Yes, you're right. I'm not exactly sure how they do that.
It looks like he may have a stucco finish on the back wall. If so, and if
good flashing is already there going under the stucco, then maybe the new
roof can go under the existing flashing (by lifting it a little?) and then
use roof cement -- I don't know; I'm just guessing.
Or, maybe channel out some of the existing stucco along the roof line (with
an angle grinder), try to run the new flashing under that and over the new
roof, and then roof cement? -- again, just guessing.

That's the general idea. I haven't done flashing with stucco or roll
roofing, so can't help there. But it's a prime candidate for a screw up
if you have a "handyman" doing a roofing job. On the other hand, might be
hard to find a roofer that wants to do a small job like that.

Don't need felt; don't use nails; make sure new flashing is waterproof;
Guys, you're in my Will (all $4.50 worth <g>) for catching angles that wouldn't have occurred to me! Let's hear it for AHR!
So I'll get rolled roofing (no more outmoded terms like "tar paper") and find a roofer that can squeeze me in.
Of course, we don't know what adding a second layer will do the junction of
the overhang and the house. At a minimum, it will probably need to be
flashed, at worse it will not work with the the house siding. Hard to say
without a picture of the top surface and the wall.

This was about whether to use shingles or sheet. Recommendation so far was for shingles. Need to put something underneath? Name of product?

Pitch is OK for shingles. What the pic doesn't show is what's on
the rest of the roof? Why doesn't that section have the same shingles
or roof as the rest of the house? That would be normal.
As far as shingles, the application is as follows:
15# or 30# felt
if you're in an area subject to snow, freezing weather, code
usually requires water barrier material from the eaves up to
2ft past the heated wall for that section instead of felt
drip edge along eaves and rakes
flashing where the roof meets the house

Here's pic showing how overhang attaches to back of house. No prob. with (what little) rain we get; it just runs off. Note that rain vent from (flat) roof does not discharge onto overhang.
Thanks for cold weather info, but not applicable here; this is So.Calif coastal.
Also, there's not a question of aesthetics -- matching the overhang to roof. Roof is flat tar paper (except in front; peak w/Spanish tiles).
Is this enough info to decide whether felt and shingles or felt and roll?
ISTR that shingles was preferred, though more expensive (?)
I'm not doing the work myself. Looking for skilled handyman. If not found, will have to bite the bullet and hope to catch a roofer between big jobs.
Thanks to all for input.

From the pic, I still can't see how it matches the rest of the
roofing, building, etc. And what you keep calling "tar paper"
is most likely rolled roofing, which is what is used on many flat
or very low pitch roofs.
So, up to you what to use. Normally, I wouldn't use a handyman
for any roofing project. One mistake and you have leaks. But if
you do, the critical area is where the roof meets the building,
which needs to be flashed correctly. And if you go with a handyman,
shingles are going to be the likely choice, I don't think many
handymen are going to do rolled roofing.
Either will work. It's up to you to decide if shingles will look
better and then there are the color choices, 3 tab or architectural,
etc. You can see what they look like at HD, Lowes, building supply
houses, neighbors houses, etc.

I'd shingle it, and I'd put roofing felt under the shingles. Roofing
felt is what is usually called "tar paper"
Heavy "tar paper" with a stone finish is called "roll roofing" which
would be your other option. With the pitch and size you have there, a
bundle of shingles should just about do the job Roll roofing doesn't
make as good a job without a lot of extra work/care.
