Always check with your local building department for specific code requirements so that you . has a map for Minimum Ground Snow Loads located at: states that Snow loads shall be determined The building mean roof height, h, must be <= 60 ft. In that case, you would designate the building is a Simple Diaphragm Building (if that is in fact true) and then the circle will change to green and you will be able to select that option since all criteria have been met. Always consult with your local building department to ensure your structure will meet the wind / snow load requirements for your area. In addition, you can estimate/verify your snow loads by Using SNOTEL in "Snow Loads for Structural Design in Montana", Use our Roof Snow Load Calculator to determine your design roof snow loads. These wind load requirements are not just for residences and buildings, they also apply to towers, signs, pavilions and covered walkways. This is required in a lot of design or building codes and can often be the governing load case in areas with high winds. Homes can and do withstand strong hurricanes, if they are designed and reinforced for the wind hazard risk of the area. This includes regularly inspecting and maintaining the structure to ensure that it is in good condition and can withstand any future potential earthquake loads. of notable changes to the wind load provisions.
