The trusses needed to be lifted to their original height and cut flush with the inside face of the cmu wall with the rotted sections removed. Connect the trusses to walls.

In reality you can do more harm than good by altering a truss and completely changing the stress and tension points on the truss. Trusses form the roof line on buildings and provide support for the lumber that holds shingles or other form of roof cover. Someone notched 4 of the studs 2 on each gable truss 1 deep and about 10 long to fit a hvac supply duct. Repairing a roof truss often requires replacing or reinforcing wood in its construction.

Reinforcing the roof s critical corner sections is a major step in unitizing a house and it can be a substantial structural improvement figure 3. Simply take 2 diagonal pieces and place them between the trusses. The cost of repairs depends on the amount of structural damage and materials required to repair it. Selection of roof trusses architectural style types of roofing material methods of support of column framing and relative economy are the principal factors influencing a choice among the three basic types of trusses.

They work through a combination of tension and compression to ensure that the timber chords and web sizes can be kept to a minimum and keep costs down. Roof trusses offer a quick and efficient alternative to a conventional timber roof but they re quite delicate when not in their fully braced vertical position.
