Please help Paint Peeling

the paint on the ceiling of my front porch is peeling pretty bad..
I don't want to just repaint it if the same is going to happen again.
the ceiling itself looks to be drywall or some type of sheet rock, what can I do to make the new paint stick better and is their a particular paint I should use....
the entire ceiling has a gray colored mildew on it and comes back pretty quick when cleaned off could this be the problem..
here is a pic of the Peeling Paint Problem

Looks like you may have a roof leak in there. Is there any way you can look in to check the inside. I don't think anything will stick till you dry it out somehow.

I see no evidence in the picture of a roof leak, or any water stains. It looks to me like the builder didn't prime the sheetrock (typical). Scrape as much off as possible, and prime it with a high quality exterior latex primer. Then paint it.

Question

i'm so curious about this, i just have to ask.....

sheetrock being used outside??? really? this is ok? i would never have imagined that you could use sheetrock for the ceiling on an exterior porch! i thought for sure the answer here would be "sheetrock can't be used outside, therefore you must rip it out & replace it with xxxxx (plywood, etc)". isn't this sheetrock just absorbing all the moisture from the elements and that's why the paint is failing?

just wondering........

Annette, I see it all the time, very common.

okay, but was it "intended" for outdoor use? it's just chalk with paper on both sides, isn't it? isn't that practically like a sponge?

i've never seen it, or maybe just didn't know it wasn't wood of some sort. wouldn't wood or beadboard or something be better?

Being that its made to be a porch roof, it is not exposed to the direct sun or rain. All newer houses (past 20 yrs. or so) have this. At least here in my little part of the world they do.

so, with proper priming & painting, sheetrock on an exterior porch ceiling will last? what about in really windy storms? the rain gets blown everywhere! and what about when you want to clean your porch in the spring with a good hosing down? to clean all the spiderwebs & crud that accumulates? can you get painted drywall wet at all?

wow, i'm still in shock..........boy, it's true - they really don't "make 'em like they used to", do they?! what did they used to use in the "good ol' days"? wood? is a sheet of drywall really that much cheaper than a sheet of plywood?

(i'm really not trying to be argumentative - this is all very educational! my co-worker who's building a house right now, is freaking out at this news!!!)

Bear in mind I don't do many exteriors anymore, so its not in my face all the time. I'm pretty sure its either fire-rated or "greenboard" drywall.

Yep, prep/prime is the key. A good finish coat wouldn't hurt either.
they really don't "make 'em like they used to",
Nope.
what did they used to use in the "good ol' days"? wood?
Yes, wood or plaster. Alot of older homes I've worked on had a type of 2" tongue in groove on the exterior porch ceilings. I always assumed it was to allow expansion & contraction (breathing) with the change of seasons.
is a sheet of drywall really that much cheaper than a sheet of plywood?
Yes, especially in the wake of recent hurricanes. I had several commercial remodels that had to be postponed due to either shortage of plywood, or the customer didn't want to pay the high materials price and opted to wait until they dropped again. And I'm sure the GC's like to save a buck anywhere they can.
