Roof-Wall Connection

The roof wall connection refers to how the roof framing (i.e. trusses) are anchored to the wall to resist the upward force that strong winds can sometimes exert on the roof. Following are the typcial types of connections that will require

	Single/Double Wraps - This refers to steel straps that wrap over the top of the truss and attach to the wall on one side of the truss only.
	Clips - This refers to steel straps that attach to the side of the truss. This option also applies if the trusses on your house are bolted to the top plate of the wall.
	Toe Nail - This refers to nails or screws driven at an angle through the truss into the top plate of the wall.
	Monolithic - This refers to two structural elements (i.e. roof and wall) that are not connected through any fasteners, but are built in a manner that they are joined monolithically. This kind of connection is more common for reinforced concrete roof decks where the roof is directly tied into masonry or concrete walls.
