Does the corrugated roofing blow off with high winds?

Corrugated metal roofing is *quite good* vs windload IF INSTALLED CORRECTLY. That means having proper-sized properly-spaced purlins; having all the wood parts of the structure strongly tied together; using proper-length rubber-gasketed roofing SCREWS, put in at the proper spacing not skipping ribs; and (this is often the cause of roof failure) do NOT have more unsupported overhang than the mfr specifies you can, usually on the order of a couple inches max for metal roofing or a fraction of an inch for plastic roofing.

The plastic stuff is ok up to a point -- the cheaper pvc stuff (Palruf etc) is not recommended for as high loads as the polycarbonate (Suntuf etc) is. You need to screw every rib in high-wind areas, and you MUST use the foam or wood filler strips that go under them, since to prevent leaks and rot you have to screw plastic through the tops of the ribs and it will compress and collapse if you do not have that filler strip under each line of screws. IT does not crack when screwed in because you are predrilling all the holes slightly larger than the screws to allow fo thermal movement. (Well actually it does not crack even if you do *not* predrill, as I have done occasionally on little scraps, but DO NOT DO THIS for your roof as it voids the warranty and is likely to cause buckling under hot or cold conditions)

Good luck, have fun,

Whoa, I think I better print all this out! Thank you so much for helping me. I would never have figured this out on my own unless it was "the hard way"

You are all GREAT!
 
I have a metal roof on my coop and I put one on the duck house this past weekend. We have some pretty strong winds and never had a problem with the roof coming loose. The nails and screws that are made for metal roofs have a rubber washer already on them, and in my opinion one is as secure as the other. The only advantage with the screw is if you need to take it off it's easier to unscrew a screw than pull out a ribbed nail.
 
Thanks everyone. I was really struggling with if the corrugated would work for me and I am feeling comfortable with it now. I appreciate all the input and advice
 
I used screws instead of nails on all parts of my coops/runs, even for attaching the hardware cloth. An electric drill/screwdriver is the only power tool I'll use, because it's pretty hard to hurt yourself with one of those, unlike a hammer and nails. I think screws make the construction more secure, too, and I know it's much easer to take things apart when you realize you've goofed as compared with things you've nailed together. Don't ask me how I know that last part.
 
We put the plastic PVC roofing on our tractors. As you can see in the photo, not many trees and we are on top of a hill. Our winds are about 60 mph here at least once a month, sometimes more often. We are called "Little Chicago" around here because of our high winds.
Though in this photo the tractor is on it's side, you can see how the roof is put on. We put roofing screws with the little gaskets all around the frame and there are 3 boards through the middle to support it when it rains and we attach to that as well but each piece of panel only has 2 screws per board.

I also put it around my smaller tractors for wind protection. There isn't anything except wire between the frame and panels. I have never had a piece to blow off.

HAAAA you probably know the last part the same way I know the last part! The hard way!!

Nadine, with winds like that doesn't it pick up your tractor and send it to OZ? I tarped 3/4 of a dog kennel for wind protection and with the winds last week I found it wedged up onto the "real" coop and bent all over like tinfoil. I guess I just have to keep learning the hard way!

Thank you for the visuals, that is really helpful.
 
We get high winds (up to 75 mph gusts) and we're windy on a regular basis (think Chicago, but in the southern california desert. If it's not 45+ mph, then it doesn't faze many in this community). We have corrugated plastic over part of the run and corrugated metal for the roof. We have never had a problem...ever. The plastic sheets are attached to the top of the metal fencing via tie wire and arched braces (it's a redneck setup to give them a dry place outside). The metal corrugated roof is attached with roofing screws that have the rubber o-rings to prevent leaks. We do have plywood underneath (we live in the desert so condensation is not issue here); however, it can be attached to braces without using plywood.
