The garage doors in your area need that rating. If you can find outswing doors that can provide that rating you're golden but since there isn't as much call for those doors I rather doubt that any company would spend the funds needed to do the test to gain the rating. You can be creative with the base door as you see in images below. There are companies out there that have rated doors with decorative elements. They duplicate the appearance of out swinging doors. I paid $1,300 for a standard double rated door. When I asked the cost to add the windows at the top it jumped to $2k to meet the rating. All these below will be considerably more than that. http://precisiondoormiami.com/hurricane-approved-garage-doors

is there an easy or less expensive way to level my sloping concrete slab to convert my carport to a enclosed garage. my slab is in great condition but if we put in a garage door on it there will be a 5 inch gap n one side. it was built like this in the 50's to allow water to drain out. Our contractor wants to charge us $15K just to dig up the old concrete, re-pour and level. That's before we even start enclosing the structure. This seems exorbitant to me just because our garage door will have large gap. I'm not sure why we need to did up the bulk of the carport floor. we know we will have o ut in a trench drain outside the entrance to the carport to keep water form getting and regrade. Help!!!!!

@Seabornman can I ask why it couldn't be converted? I see them converted into garages all the time in this area (NC). I understand foundation and support might be more of an issue with an addition above it, but I have not seen many completely demolished.

Be sure the concrete man understands you want the floor finished smooth…then after stain… add a clear coat sealer for a pretty durable…shiny finish..it is also necessary to make striations in the concrete to prevent cracks as it settles…also keeping in mind the added weight may require more support than a regular floor …even if you have a slab foundation it will be wise to add re- bar into the slab to prevent big cracks…the green is my favorite of any of the choices…over time added liquid wax will keep it shiny if needed….my favorite floors ever in our home
