- Hurricane Prep for roof
I'm thinking about adding roof tie downs to my house. My house already has the standard tie downs as required by code. I'm not sure if what I want to do will help, so let me describe. I have 1 foot eaves all the around my house, and I want to use lag bolts to attach anchors to the eaves approximately every 10 feet. I then will place 5 foot augers in the ground and when a hurricane approaches, attach the auger and the anchor on the house together together with chain or heavy duty straps. Now the questions are: Will this help hold down the roof more than the standard hurricane straps? If the hurricane is severe enough, will the augers and/or straps hold? How much lifting force can a hurricane place on a roof with a 1 foot overhang?
I found a group called the Institute for Building and Home Safety -- started by insurance folks to cut down on losses and injuries. They had a booklet you could print off with adobe on how to retrofit your home to prepare for a hurricane. Haven't really reviewed it personally, but there were other items that might be helpful too. Their main site is www.ibhs.ord -- The publication is about 1/2 way down on this page: http://www.ibhs.org/html/publications/Default.htm
Also, you might want to check out www.strongties.com -- they make tie down systems and they may have some specifics you'd find helpful.
