Roof To Wall Connection

They transmit the vertical dead load and live load to the bearing walls.

Roof to wall connection.

Individual connections and connections within full scale roof systems were tested to quantify potential system effects. An affidavit of compliance with roof to wall connection shall be provided to the roofing inspection at the time of the first roofing inspection. In older wood frame construction the connection of roof trusses or rafters to walls is 2 or 3 sixteen penny 16d nails driven at angles toe nailed through the rafter or truss into the top plate of the wall. There are qualifications that these houses need to meet and if your home meets these standards you may be eligible for assistance with important work on your roof to wall connections.

It is also used when the wall below provides a ledge with sufficient bearing area for the roof to bear on directly. They function as diaphragms transmitting lateral wind and seismic loading through the walls to the foundation. Although the forces occur at the same placed on hip roofs the roof structure is such that it is the very corner truss or rafter called the jack that needs to well connected. In an older masonry house the truss rafter may be toe nailed to a wood plate that is bolted to the tie beam at the top of wall.

Hand driven and pneumatic fasteners were included in the test program. Roof to wall connections only a licensed general building or residential contractor shall install the roof to wall connections retrofits. This affidavit shall be completed by the contractor. A direct bearing connection is used in instances where the wall below does not continue beyond the roof level i e no parapet.

For example roof replacement is required for detached single family homes with a value of 300 000 or more that fall in the wind borne debris region that covers nearly half of the state s southern tip. Floor and roof systems for use with loadbearing structural concrete masonry walls serve three primary functions. One way to gain access is to take up roof decking at the eaves as shown in figure 2. Consequently for gable end roofs the most important roof to wall connections are those within 6 to 8 feet of the outside corners.

The direct bearing connection is the simplest and most common connection in the home building industry. If the roof wall connection isn t accessible from inside the attic and the inspection indicates that you have to add hardware you will need more than just a peephole.
