Abstract: In a building having a roof with multiple spaced rafters sitting on side walls, this is apparatus for holding the roof on the side walls both vertically and horizontally during high side wind forces. There are plurality of attachment fixtures carried by respective ones of opposite ends of adjacent rafters along a length of the roof. A plurality of ground anchors are disposed at respective ones of ends of the rafters opposite the opposite ends carrying the plurality of attachment fixtures. Finally, a plurality of straps are connected between respective ones of the plurality of attachment fixtures and the plurality of ground anchors. The straps are releasably attached so that they can be stored and only be attached when a hurricane or the like is likely. The attachment fixtures distribute forces to the whole rafter end and avoid rafter-splitting forces.
