Yup. Wherever two 2 xs meet, I install a plate PLUS HUGE J-bolts into the slab, thru the plate, capped by a steel "u" shaped member that ties two adjacent wall studs to the plate. Roofing ply is screwed and glued to the rafters as well.
Wide: The straps, properly screwed in, can reduce separation due to shaking such as you might get in a moderate tremblor. Nails suck for anything but compressive loading where there is no movement.
BTW...Tile roofs....
Terry:
I wonder about their use in hurricane prone areas. They have a tendency to get blown loose and make excellent projectiles for the wind to play with. Also, if used on a trussed roof that has been constructed with "gang" nails, (plates with teeth that only go in about 3/4 inch for the rest of you guys), when there is fire, the gang nails lose their grip and the roof collapses under the extreme load of the tile. Ask a fire department if they like tile roofs.
