Here is a photo of the roof from the inside of the shack. For the storm of sandy I only had half the nails in and didn't get any damage. I was able to nail to the trusses and the top and bottom of 2"x4"s. I added the 2x4s between the trusses to nail to also.
Thanks Linedropper, that helps alot. Now I have ideas as I should be doing the roofing either today or tomorow, inbetween football comercials mind ya, lol.
