Does the corrugated roofing blow off with high winds?

    Good Morning,

    I would like to use the corrugated roofing material but am worried about our high winds we get here sporadically. Last week it was 46 MPH for a couple of hours. That can do alot of damage.
    Do you just nail it down and does it get ruined (bending) by wind?

    Thanks!

    You need a good frame structure, a wood frame is fine and the metal screws designed for metal roofs. I would always go with screws over nails. During Katrina, we had over 100 big trees down from wind but the metal roof was fine, except for the holes in it from trees falling. It will not lift up or blow away when secured properly.

    We also always use sheet metal screws. The nails will pull out with the high wind. [​IMG]

    We get lots of high wind here in Ok. [​IMG]

    Oh thanks! I was talking to my Dad and he said nails. I never thought of screws!! Do I need to silicone around the screws and I am guessing that I put the roofing over plywood?
    Guess you can tell I am not a carpenter huh? I can do this...I can do this...Chickies need more room.

    Use gasketed screws. They will not leak or let go.

    Thanks for the help, guess I am going to Home Depot.

    One more question if anyone has time. Has anyone used the plastic looking corrugated? It looks nice but I was thinking it would crack when it was screwed in.

    We used vinyl PalRuf, the clear variety, though you can get it in various opaque colors too. No cracks. Be sure you use the proper screws with a rubber gasket and that you gently secure each one- you can test for leakage with a container of water, too. We spaced our supports 1 foot apart even though the instructions suggested 2 feet- we're in such a windy location that is seemed to be worth the effort and expense.

    If you scroll 3/4 down this page you'll see our hurricane hangers on the run, a template made to baffle wind and yes, use screws, preferably the kind with rubber washers. We've been through some devastating winds and one hurricane...

    How about washers along with screws for extra support with the wind

    The roofing screws have a rubber gasket that molds around the hole, I would not use a washer as it will probably cause leaks.

    I would not put the metal directly on plywood. It can cause condensation. I's suggest something like this photo. Put the long beams that run along the slope on end (rafters), then put the cross beams (purlins) (I'd suggest 2x4's) to attach the metal to. For my metal roof, I have 2' spacing on the purlins and it worked well during a very high wind. If you use the plastic, I'd suggest talking to the people at Home Depot(since that is where you are going) or check with the manufacturer for suggested spacing. I also favor the screws with the rubber on them to attach the metal or plastic. Again, check with the people at Home Depot for recommended length and style.

    A failure I had was not the metal coming lose from the purlins but the purlins coming lose from the rafters. The metal and purlins actually stayed together as panels and one panel flew over 200 feet. The previous owners used 2-1/2" smooth nails to attach the purlins to the rafters. When I rebuilt it, I used 3-1/2" ribbed nails.
