    I am not a builder.
    I am good with building if I can get help on how to approach things.
    I am looking for advice on an easy way to secure a roof to the frame of my run.
    It will be a 8'x10' roof with Corrugated Tuftek Paneling that will be attached to a 6'x9' Frame.
    One long side of run sits at 7' and slopes down to 6' (over the 6' distance).
    Tips? Pictures? Any advice?
    I know how to build the roof, just not sure the easiest way to attach it... (notching, metal braces etc)
    Thanks,
    Steve

    Go here www.lowes.com and in the search box type hurricane strap or rafter tie and there is your answer any of these will work and they are numerous of others you can use it is according to what they have in stock. Another option is cutting what is called is a birds mouth in the 2x4 rafter that your putting in but those arent for the faint of heart but the straps is the easiest.

    If you are looking to attach the roof frame to the walls - yes -Huricane strap. They are $0.20 each or so. Just nail or screw to the wall fram & then to the top frame.

    If you are looking to attach the corrugated roof panels directly to the wall frame buy the roofing nails with the rubber gasket. You should get at least 1 inch nails - probably 2inch. Then just nail them on.

    Hope this helps.

    You live in snow country; make real REAL sure you have built a snow-load-worthy beam-and-rafter system to support the roof, and that the run posts (size, spacing and solidity) are sufficient unto the task.

    If the roof will be 8x10, the frame needs to be 8x10 too -- you cannot have more than about 1/2" of overhang of that plastic roofing beyond the sides of the wooden support structure, or 1" beyond the top/bottom edge of the wooden support. Larger amounts of unsupported plastic will tend to cause the whole thing to blow off in the wind.

    Get the mfr's installation sheet (available online, or as a pamphlet where the roofing panels are sold) and follow it TO THE LETTER.

    Good luck, have fun,

    Pat

    The framing for the roof will be 8'x10' which will be secured to a frame that is 6'x9'.
    I want an overhang of @ 6" on the sides (short ends) and +/- 1' overhang on the long side.
    So, the roofing will have 'eaves' for rain run-off, but the paneling will not overhang the roofing frame itself.

    It sounds like a simple shed roof. JBowen9 is right. Hurricane straps will work well. Don't need to notch any roof rafters. Hurricane straps will nail to your walls and to the roof rafters. Generally you would slop your top plate (horizontal board at the top of the wall) on both walls to match the 6' and 7' heights then attach the roof rafters with hurricane straps. We did something similar for our coop, you can check out our "my page" for photos.

    Also, great advice from patandchickens on the roofing.

    Sounds like it's going to be a great coop. Be sure to take pics so we can see it! Have fun. [​IMG]

    The tops of my walls will not be sloped to match the angle - although I am pretty sure that is not necessary. I will take some pix and post what I am facing. I know it should be easy, I have just never done it. Not sure what kind of straps to buy, and exactly how they will connect. Top of 6' and 7' walls will be flat 2'x4's... Love to see some pix of how Hurricane straps connect in my case...

    enggass, try this... these are computer drawings of different types of hurricane strap applications from strongtie (the manufacturer). From what you said you may want to notch the rafters where they are going to attach to the top plates of your wall.

    http://www.strongtie.com/products/connectors/h.asp#gallery2

    go to the very top of the page and you'll see the strap I was recommending. these can be purchased at either Home Depot or Lowes.

    Thanks a lot. Currently I only have a single 2x4 at the top of my walls, not 2. I know it is customary to have 2, but this is just a run, not a 'building'. Do I have to run another in order to use one of these ties? or can I make it work as is with just one?

    Nope, I don't see any great reason. A double top plate is primarily used when you have to butt boards together. The second board keeps them from pulling apart or moving. It shouldn't hurt anything for the hurricane straps to hang down below the plate. Cosmetics would be the greatest issue on this.

    Also, if you do notch your rafters make as small a notch as possible. I assume you are using 2x4's and you don't want to take any more meat out of the board than you have to. A simple framing square will help you draw out the notch and then use a saw you feel comfortable with to cut it. If you believe you need it, 2x6's are not that much more expensive for the size of coop your building and you'd be able to make a deeper notch.

    Hope this isn't too much info.
