The first step is to find out how many rafters are sagging and if anything else is damaged.

Raising sagging roof rafters.

So you should start by inspecting the roof from the under side or attic. Remove the chisel and wet the crack with a wet rag. Drill holes in angle iron. Spread polyurethane glue into the crack with a stiff bristle brush.

If there is any other damage it should also be fixed before moving to the next step. Push up on the plywood until the foam is touching the roof decking s underside. The first and foremost step is to find out how many and from where the rafters are sagging. Sagging rafters may be the result of having framed the roof with lumber of dimensions smaller than current building standards such as using 2x4s or 2x6 s or there may be damage to the framing from insects or rot.

Determine the extent of damage. Place a fascia board up under the roof sheathing and nail it with a hammer across the ends of the rafters to strengthen them. You may find that. Place the plywood and styrofoam side up against the damaged roof decking.

Force open the cracked end of a sagging rafter with a wood chisel. Actuate the intensity of damage.
