Abstract: It's now accepted that hurricane tie-down straps should be wrapped over the top of rafters/trusses, avoiding the crucial weakening effect of wood splitting around the nails of common side-nailed straps. That “wrap-over” is easy to do during construction but has been difficult and costly to do for existing houses, where the sheathing and roofing is in the way. But now such wrap-over can be an easy retrofit, according to this invention: Without damaging sheathing or roofing, force the sheathing off the rafter/truss just enough to allow a special strap to be pushed through the gap, then proceed much as in new construction. Unique wedge-blade and lever types of devices quickly create just the right gaps.
