I don't know what type of soil you have but my dad in Florida used mobile home auger stakes to secure his workshop and "Florida room". These stakes are 5 feet long, 1/2 diameter steel. The top has a loop that you put a 2x4 in as a lever. You then cork screw into the ground. He used three on each side, threw cable over the roof and a come along hand winch to tighten them down. He lost some shingles thats about it <img src="/forums/images/graemlins/cheers.gif" alt="" />
