Heavy-duty pipe staging equipped with steel cradles supported a grid of aluminum I-beams used to lift the rafters off the wall.
Shoring jacks at the base and adjustment screws at each cradle allowed the roof to be raised carefully and remain level.
Six steel tie rods connect the horizontal glulam beam at the exterior wall top plate to the floor diaphragm beneath the balcony.
Heavy steel H-brackets installed between the second-story floor joists receive the interior ends of the tie rods.
The two-part brackets have sliding adjustment slots to allow for variation in the width of the joist bays.
Because the weight of the roof was being carried by scaffolding, nylon ratchet straps hooked to the steel brackets were sufficient for pulling in the leaning wall.
Hurricane clips tie the rafters to the floor joists at the front of the house; shown here is a section of the attic behind a knee wall.
