In years past, the recommendation was to always be underground in the event of a severe storm mainly because it was all we had. Today the argument still exists between above ground shelters and below ground shelters for severe storm protection. However, we believe based on professional research opinion that above ground safe rooms are the safest choice to make based on past events where below ground storm shelter occupants were drowned from water collection or asphyxiated from poor ventilation due to home debris stacking up on the door trapping them inside. We are sure that there are companies out there that do a great job addressing these concerns, however, we choose to provide above ground safe rooms to protect your family and ours as well.
