I will be building a 35' x 70' wood framed metal structure soon. I plan on sheeting in the roof only this year and the walls next year.
My concern is that I'm building in a very windy area in Kansas and I'm worried about the roof blowing off.
I plan on using hurricane straps, but I was wondering if I also need a way to relieve the air from building up pressure under the roof. Thanks for all and any ideas. -Mark

What is the pitch of the roof? It does sound a bit like tempting disaster.
